A golf battery is a deep-cycle battery designed to power electric golf carts, providing steady current over long periods for propulsion, accessories, and inclines. Typically 6V, 8V, or 12V units wired in series (36V/48V systems), they use lead-acid or lithium-ion chemistries for reliability and torque. Pro Tip: Lithium batteries last 3x longer than lead-acid with no maintenance.

Advanced EV vs ICON Golf Cart Comparison

What powers electric golf carts?

Golf cart batteries supply continuous low-speed torque for motors, prioritizing cycle life over peak power. Lead-acid (FLA/AGM) offers affordability but requires watering, while lithium (LiFePO4) packs reduce weight by 40% and charge faster.

Electric golf carts rely on 36V or 48V battery banks—six 6V batteries for 36V systems. Lithium-ion variants like LiFePO4 deliver 2,000+ cycles versus 500-800 for lead-acid. Why does chemistry matter? Thermal stability impacts safety during summer heat. For example, a 48V 100Ah LiFePO4 provides 4.8kWh—enough for 35-45 miles per charge. Pro Tip: Use torque-specific motor controllers to prevent voltage sag on hills.

How do you maintain golf cart batteries?

Maintenance involves checking water levels (lead-acid), cleaning terminals, and avoiding full discharges. Lithium batteries need no watering but require balancers for cell equilibrium.

For lead-acid: Refill with distilled water post-charging to prevent sulfation. Terminals corrode if not cleaned monthly—use baking soda paste. But what happens if you neglect maintenance? Voltage imbalances drain functional cells. A 48V system might drop to 42V under load, reducing speed by 25%. Pro Tip: Equalize lead-acid batteries monthly to reset cell voltages. Lithium packs need SOC kept between 20%-80% for longevity. Example: A $1,200 lithium pack saves $600 in replacement lead-acid costs over 5 years.

What’s the optimal charging practice?

Charge after each use, avoiding deep discharges below 50%. Use smart chargers with temperature compensation to prevent overvoltage.

Lead-acid requires full 100% charges to prevent sulfation; partial charging slashes lifespan by 30%. Lithium prefers partial charges—stop at 90% for daily use. Imagine charging like refilling a gas tank: Lead-acid needs a full refill, while lithium thrives on frequent top-offs. Pro Tip: Store carts at 50-70% charge if unused for weeks.

What factors affect battery lifespan?

Cycle depth, temperature extremes, and charging habits dictate longevity. Lead-acid lasts 4-5 years; lithium lasts 10+ with care.

Discharging lead-acid below 50% DoD (depth of discharge) halves cycle life. Lithium handles 80% DoD gracefully. Why does heat matter? Above 30°C (86°F), lead-acid loses 25% capacity annually. Store carts in shaded areas—direct sun raises internal temps by 20°F. Example: Arizona users report 3-year lead-acid lifespan vs 6 years in mild climates. Pro Tip: Install battery fans for carts used in hot regions.

How Long Can a Golf Cart Sit Unused?

When to replace golf cart batteries?

Replace when runtime drops 30% or charge time spikes. Lead-acid shows swollen cases; lithium exhibits BMS errors.

Test voltage under load: A 48V bank below 46V at 50% SOC needs replacement. For lead-acid, 12V batteries reading under 10.5V post-charge are faulty. Think of it like tires—bald treads mean replacement time. Pro Tip: Load test batteries annually—voltage drops below 1.8V per cell under load indicate failure.

Can golf batteries power other devices?

Yes—they’re used in solar storage, wheelchairs, and marine applications needing deep-cycle endurance. Voltage must match the device’s specs.

Golf cart batteries work for low-RPM, high-torque systems. A 48V LiFePO4 pack could power a small boat trolling motor for 8 hours. But does mixing applications affect warranties? Most manufacturers void warranties if used outside golf carts. Pro Tip: Add an inverter for 120V AC devices but stay within 80% of max discharge rate.

FAQs

Lithium batteries consist of four core components: a cathode (typically lithium metal oxides), anode (graphite or silicon alloys), electrolyte (lithium salts in organic solvents), and a separator. These elements enable ion movement between electrodes during charge/discharge cycles. Advanced variants like NMC or LiFePO4 optimize energy density and safety for applications ranging from smartphones to electric vehicles (EVs).

ICON EV Golf Cart Costco Membership Offer

What materials form the cathode in lithium batteries?

The cathode is built from lithium metal oxides like LiCoO₂ (LCO), LiMn₂O₄ (LMO), or LiNiMnCoO₂ (NMC). These compounds host lithium ions during discharge and determine capacity/voltage. High-nickel NMC variants (e.g., NMC811) now dominate EV batteries for their 200–220 Wh/kg energy density and thermal stability up to 210°C.

Cathode materials define a battery’s voltage and energy storage capacity. For instance, LiCoO₂ operates at 3.6V but suffers from cobalt’s cost and toxicity. Meanwhile, LiFePO₄ (LFP) offers lower voltage (3.2V) but superior cycle life (3,000+ cycles) and thermal safety. Pro Tip: Avoid exposing cathodes to moisture—hydrolysis reactions can form toxic HF gas. A Tesla Model 3’s 82kWh NMC battery contains ~12kg of nickel and 1.5kg of cobalt. Comparatively, CATL’s LFP cells use iron-phosphate, slashing costs by 30% but reducing energy density by 15%.

Why is graphite used for lithium battery anodes?

Graphite anodes intercalate lithium ions efficiently, providing stable 372 mAh/g capacity. Their layered structure minimizes expansion (<4%) during charging. Alternatives like silicon (4,200 mAh/g) suffer from 300% volume swings, requiring nano-engineering for practical use.

Beyond its structural reliability, graphite’s low cost and conductive properties make it the anode default. During charging, lithium ions nest between graphene layers without breaking bonds—like books sliding onto a shelf. However, dendrite growth on aged anodes can pierce separators, causing shorts. Pro Tip: Keep lithium batteries between 20–80% charge to slow anode degradation. For example, Sony’s 18650 cells pair graphite with silicon oxide coatings to boost capacity by 10% while limiting swelling. Future trends include silicon-graphite hybrids targeting 450 Wh/kg by 2030.

How do electrolytes function in lithium batteries?

Electrolytes facilitate ion transfer via lithium salts (LiPF₆) dissolved in organic carbonates. They conduct ions while insulating electrons, sustaining cell voltages up to 4.2V. Solid-state variants (e.g., sulfide glass) promise greater safety but face challenges with ionic conductivity at room temperature.

Electrolytes must balance ion mobility and stability. Traditional liquid electrolytes use ethylene carbonate/dimethyl carbonate solvents, but they’re flammable above 35°C. Additives like vinylene carbonate form protective SEI layers on anodes, preventing solvent decomposition. Practically speaking, a punctured iPhone battery ignites because oxygen reacts exothermically with the electrolyte. Solid-state designs, like Toyota’s prototype sulfide-based cells, eliminate flammability but require precise pressure to maintain electrode contact. What’s the trade-off? Solid electrolytes currently operate 40% slower than liquids at 20°C.

What role does the separator play?

The separator prevents electrical shorts by physically isolating the cathode and anode. Made from porous polyethylene/polypropylene films, it allows ion flow while blocking electron transfer. Advanced ceramic-coated separators shut down at 130°C by melting pores closed, averting thermal runaway.

A separator’s porosity (typically 40%) and thickness (16–25µm) balance ion flow and mechanical strength. For example, Tesla’s batteries use trilayer separators that stiffen under heat, reducing rupture risks. But what happens if the separator fails? Dendrites can bridge electrodes, triggering rapid self-discharge and heat buildup—the infamous “runaway” scenario in Samsung’s Galaxy Note 7. Pro Tip: Store lithium batteries at 50% charge in cool, dry environments to minimize separator stress. Innovations like Asahi Kasei’s HIOP layer integrate shutdown features and higher puncture resistance for EV packs.

Maryland’s Golf Cart Laws by County

How are lithium batteries recycled?

Recycling involves hydrometallurgy (acid leaching) or pyrometallurgy (smelting) to recover cobalt, nickel, and lithium. Direct cathode recycling retains material structures, cutting reprocessing costs by 40%. Only 5% of lithium batteries are recycled today due to logistical and technical hurdles.

Pyrometallurgy smashes batteries into a molten bath at 1,400°C, recovering alloyed metals but losing lithium as slag. Hydrometallurgy dissolves components in sulfuric acid, achieving 95% cobalt recovery—Umicore’s process powers this method. However, volatile lithium prices often make recycling uneconomical. For perspective, recovering 1kg of lithium costs $5 but sells for $15, whereas cobalt’s $33/kg value drives most programs. Pro Tip: Always tape battery terminals before disposal to prevent residual charge fires. Redwood Materials’ closed-loop system recycles 95% of battery metals for reuse in Panasonic’s Gigafactory cells.

FAQs

How Long Can a Golf Cart Sit Unused?

Golf cart batteries are deep-cycle units engineered for sustained depth of discharge (DoD) up to 80%, while car batteries provide short, high bursts for engine cranking. Golf carts typically use six 8V lead-acid batteries (48V total) versus cars’ single 12V starter battery. They’re built with thicker plates for 500–1,000 cycles versus 30–50 shallow cycles in automotive units. Lithium golf cart batteries now offer 2,000+ cycles with 100% DoD.

Yamaha G2 Golf Cart Timeless Classic

What defines a golf cart battery’s discharge cycle?

Golf cart batteries prioritize deep discharge capacity over cranking amps, using reinforced lead plates to withstand 50–80% DoD daily. Car batteries use thinner plates optimized for brief 2–5% discharges. For example, a Trojan T-105 flooded battery delivers 115Ah at 20h rate vs. a car battery’s 650 CCA (Cold Cranking Amps). Pro Tip: Never discharge golf cart batteries below 50% DoD—it halves their lifespan.

Deep-cycle batteries use paste-type positive plates that resist active material shedding during deep discharges. In contrast, car batteries employ grid-style plates for maximum surface area to deliver quick energy bursts. But what happens when you demand extended runtime from a starter battery? The thin plates warp, causing internal short circuits. Transitionally, golf cart systems often integrate battery monitors to maintain 50–80% state of charge (SoC), whereas cars rely on alternators to keep batteries near 100% SoC.

Why are voltage configurations different?

Golf carts require higher system voltages (36V/48V) for torque efficiency, achieved by linking six 6V or eight 6V batteries. Cars use standalone 12V for lower current in thin wiring. A 48V golf cart battery bank draws ~100A under load versus a car’s 300–600A cranking spikes. Practically speaking, this impacts cable sizing—golf cart battery interconnects are 6 AWG versus cars’ 2 AWG jumper cables.

Higher voltage reduces resistive losses over long cable runs common in EVs. For instance, a 48V system moving 2kW requires 41.7A, while a 12V system needs 166.7A—quadrupling copper costs. However, most automotive accessories (radios, lights) operate at 12V, requiring golf carts to add voltage reducers. Pro Tip: When upgrading to lithium, opt for 51.2V LiFePO4 packs—they’re drop-in replacements for 48V lead-acid systems without voltage reducers.

Legal Age to Drive a Golf Cart in Michigan

How does chemistry differ between the types?

Flooded lead-acid (FLA) dominates golf carts for its cost-effective deep cycling, while AGM (Absorbent Glass Mat) car batteries handle vibration better. Lithium golf cart batteries (LiFePO4) now offer 2,000+ cycles but cost 3x upfront. Case in point: A 48V 100Ah lithium pack stores 5.12kWh versus 4.8kWh in lead-acid but weighs 70 lbs less.

Lead-acid chemistry relies on sulfuric acid electrolyte for ion transfer. In deep-cycle FLA batteries, the electrolyte reservoir allows periodic watering to counter hydrogen gas loss. Automotive AGM batteries immobilize the electrolyte, making them spill-proof but less tolerant of deep discharges. Lithium iron phosphate (LiFePO4) operates via lithium-ion intercalation, providing flat discharge curves—meaning your golf cart won’t slow down as the battery depletes. Transitionally, while lithium has superior specs, many golf cart owners still prefer FLA for its $1,200 vs. $3,500 price point.

What about charging protocols?

Golf cart chargers apply multi-stage charging (bulk/absorption/float) over 8–10 hours for lead-acid health. Car alternators use single-stage charging at higher voltages (14.4V), which overcharges golf cart batteries. For example, a 48V lead-acid system needs 59.2V absorption voltage, while a car alternator would push 14.4V per 12V battery (57.6V total), risking undercharging.

Lithium golf cart batteries simplify charging with built-in BMS units that communicate with smart chargers. These adjust voltage curves dynamically—LiFePO4 absorbs at 58.4V (3.65V/cell) versus lead-acid’s 59.2V. But can you use a car charger in a pinch? Only with lithium packs featuring auto-voltage detection, and even then, limit it to 80% charge to avoid cell imbalance.

What’s the difference between 36V and 48V golf cart batteries?

36V systems (six 6V batteries) dominated pre-2000 carts but now lag in performance. 48V configurations provide 33% more power efficiency and torque, crucial for hilly terrains. Pro Tip: Upgrading to 48V? Replace the motor controller – older units can’t handle increased voltage spikes.

36V systems cap at ~2.5kW output, limiting speed to 12–15 mph. Modern 48V packs deliver 4–6kW, enabling 19–24 mph with better hill-climbing. For example, a Yamaha Drive2 equipped with 48V/210Ah batteries achieves 35 miles on rolling courses versus 22 miles with 36V. Transitionally, while 36V suffices for flat courses, lithium upgrades now make 48V the baseline. Warning: Mixing old 6V and new 8V batteries creates imbalances – replace all simultaneously.

Lead-acid vs lithium: Which battery type dominates golf carts?

Lead-acid (LA) still holds 70% market share due to lower upfront costs ($900–$1,200 vs $2,500+ for lithium). However, lithium batteries offer 3x cycle life – 2,000 vs 600 cycles – and charge 3x faster. Pro Tip: Lithium’s 100% depth of discharge capability effectively doubles usable capacity versus LA’s 50% limit.

A 48V 100Ah lithium pack weighs ~110 lbs versus 600+ lbs for equivalent LA, reducing tire wear. Golf course operators report 40% energy cost savings with lithium despite higher initial investment. For instance, Club Car’s Onward LiT models now use 48V/105Ah lithium, achieving 60 miles per charge. Beyond weight savings, lithium maintains voltage stability under load – crucial for maintaining 19 mph uphill. But why haven’t lithium carts dominated? High retrofit costs and outdated charger infrastructure slow adoption.

How do I calculate golf cart battery capacity needs?

Use Ah = (Watt-hours/day) / (System Voltage × DoD). For a 48V cart driven 20 miles daily: 20 miles × 40 Wh/mile = 800 Wh. LA batteries at 50% DoD: 800/(48×0.5)=33.3Ah minimum. Lithium allows 100% DoD: 800/48=16.7Ah. Pro Tip: Add 20% buffer – real-world terrain varies.

Assume a 48V cart with 4kW motor: Peak current draws hit 83A (4000W/48V). Batteries must sustain 1C rates – a 100Ah pack handles this comfortably. For weekend golfers: 50Ah LA suffices for 18 holes (≈12 miles). Transitionally, while formulas help, terrain matters – hilly courses need 25% more capacity. Ever see carts stranded on steep fairways? Undersized batteries sag voltage, triggering premature low-voltage cutoffs.

How often should you water golf cart batteries?

Flooded lead-acid batteries require watering every 4–6 weeks during active use. Maintain levels ¼” above plates—overfilling risks acid spills, underfilling accelerates sulfation. Lithium-ion and AGM batteries are maintenance-free. Pro Tip: Water only after full charging to prevent overflow from electrolyte expansion.

Deep Dive: Lead-acid batteries lose 5–15% electrolyte monthly through gassing during charging. Use a hydrometer to measure specific gravity (1.225–1.265 indicates healthy cells). For example, a golf course fleet topping batteries monthly saw 18% longer lifespan versus quarterly watering. Always wear gloves—battery acid causes skin burns. Transitional Tip: Beyond watering, equalize charges every 3 months to balance cell voltages. Table below compares watering needs:

What’s the optimal charging routine for longevity?

Charge after every use, even partial discharges. Lead-acid must reach 100% SoC weekly to prevent sulfation. Lithium-ion prefers 30–90% cycles. Avoid trickle charging—modern chargers auto-shutoff. Pro Tip: Let batteries cool 30 mins post-use before charging to reduce thermal stress.

Deep Dive: Charging generates heat—lead-acid tolerates up to 50°C, lithium-ion 45°C. A 48V lead-acid system needs 59–63V input; 72V lithium requires 84V CC-CV charging. For example, a resort extended battery life 22% by installing timer-controlled charging during off-peak hours. Transitional Note: Temperature matters—charging below 0°C causes lithium plating. Use insulated battery blankets in cold climates. Consider this charging comparison:

How to prevent terminal corrosion effectively?

Apply anti-corrosion spray or petroleum jelly post-cleaning. Remove oxide buildup with a wire brush and baking soda paste. Tighten connections to 8–10 Nm torque—loose terminals arc and overheat. Pro Tip: Use felt washers soaked in corrosion inhibitor around terminals.

Deep Dive: Corrosion starts when sulfuric acid fumes react with lead terminals. A study showed unprotected terminals lose 40% conductivity within 6 months. For instance, a maintenance team reduced corrosion-related failures by 65% after quarterly terminal treatments. Transitional Tip: Beyond cleaning, inspect cables for fraying—high resistance in damaged wires forces batteries to work harder. Ever seen a corroded battery catch fire? It’s rare but possible when sparks ignite hydrogen gas.

Does storage temperature impact battery lifespan?

Yes—store at 15–25°C (59–77°F). Lead-acid self-discharges 5% monthly at 20°C vs 20% at 40°C. Lithium-ion loses capacity if stored at 100% SoC in heat. Pro Tip: For winter storage, charge lead-acid to 100% and lithium-ion to 60% before disconnecting.

Deep Dive: High temps accelerate chemical reactions—for every 10°C above 25°C, lead-acid lifespan drops 50%. Lithium-ion stored at 40°C and 100% SoC loses 35% capacity yearly versus 4% at 25°C/60% SoC. For example, a dealership reduced warranty claims by storing demo carts in climate-controlled rooms. Transitional Note: Think batteries are safe in garages? Not if temps swing from freezing to 38°C seasonally—invest in thermal covers.

When should you replace golf cart batteries?

Replace lead-acid when capacity falls below 60% (usually 4–6 years). Lithium-ion packs last 8–12 years but check BMS health annually. Warning signs: slow acceleration, reduced range, swollen cases. Pro Tip: Capacity-test batteries yearly—load testers reveal weak cells before failure.

Deep Dive: A 48V lead-acid pack with 220Ah new capacity needs replacement at 132Ah. Voltage drop under load below 46V often signals failure. For instance, a retirement community avoids breakdowns by replacing all batteries at 5 years regardless of condition. Transitional Tip: What’s worse than a dead battery? Three old ones and one new—replace entire banks together to prevent imbalance.

Can you mix old and new batteries?

Never mix old and new batteries—mismatched internal resistances cause overcharging/undercharging. Replace all batteries in the bank simultaneously. Pro Tip: Label batteries with install dates—rotate positions if one fails prematurely to equalize wear.

Deep Dive: Mixing a new 250Ah battery with a 180Ah used one forces the weaker unit into reverse charging. A golf club ruined a $1,200 bank by adding one new battery to a 2-year-old set—result: thermal runaway in three months. Transitional Note: Think you’re saving money? The average cost of premature replacements due to mixing exceeds full set replacement by 70%.

Maryland’s Golf Cart Laws by County

The ideal voltage for golf cart batteries balances performance and efficiency, typically 36V, 48V, or 72V. Modern lithium-ion (LiFePO4) systems at 48V dominate due to superior energy density, 20–30% longer range, and faster charging than lead-acid. Voltage selection hinges on terrain, payload, and motor specs—hilly courses demand higher voltage for torque. Always match the battery to the controller’s voltage rating.

Maryland’s Golf Cart Laws by County

What factors determine the ideal voltage for a golf cart?

Key factors include terrain gradient, passenger load, and motor efficiency. Steep hills demand higher voltage (48V/72V) to sustain torque, while flat courses work with 36V. Battery chemistry (LiFePO4 vs. lead-acid) also impacts voltage stability under load. Pro Tip: Use a 48V LiFePO4 pack if your cart carries 4+ passengers regularly.

Golf carts face dynamic power needs—climbing a 15% incline at 10 mph requires 30–50% more current than flat terrain. A 48V system reduces amperage draw by 25% compared to 36V, minimizing heat buildup in cables. For example, a 48V 100Ah LiFePO4 battery delivers 5.12kWh, powering a 3.5kW motor for 90 minutes. Mechanical brakes? They’re voltage-agnostic, but regenerative braking works best with lithium packs. Transitionally, higher voltage doesn’t always mean better performance—oversized systems add weight. Always verify motor windings support the target voltage; mismatches cause efficiency drops or overheating.

How does 48V compare to 36V systems?

48V systems provide 20% more torque and 15% longer range than 36V. They operate at lower current, reducing energy loss as heat. Lithium 48V packs also charge 2x faster than lead-acid. Pro Tip: Upgrade to 48V if retrofitting older carts—modern controllers handle regenerative braking better.

A 36V lead-acid pack (6x6V batteries) weighs 300–400 lbs, while a 48V LiFePO4 equivalent cuts weight by 60%. This directly improves hill-climbing efficiency. For instance, a 48V cart on a 10% slope uses 55A vs. 70A for a 36V system, preserving battery lifespan. But what if your course is flat? 36V suffices for speeds under 15 mph. Transitionally, 48V’s downside is cost—initial setup is 30% pricier but pays off in 2–3 years via lower maintenance. Check your charger’s compatibility: 48V requires 58.4V (LiFePO4) or 57.6V (lead-acid) charging voltage.

When is a 72V battery system necessary?

72V systems suit heavy-duty carts with payloads over 1,000 lbs or speeds exceeding 25 mph. They’re common in commercial resorts or modified carts with lifted suspensions. Pro Tip: 72V’s higher RPM risks motor bearing wear—install a temperature sensor.

With 72V, controllers and motors must handle 84V (charged LiFePO4). A 72V 120Ah pack stores 8.64kWh, enabling 60–80 mile ranges. But practically speaking, most golf carts don’t need this voltage—it’s overkill for standard 4-seaters. However, for towing or extended off-road use, 72V’s reduced current minimizes voltage sag. For example, a 72V cart climbing a 20% slope at 12 mph draws 100A vs. 150A at 48V. Transitionally, wiring upgrades are mandatory—thicker gauge cables handle the increased power. Always pair 72V batteries with UL-listed chargers to prevent BMS faults.

What are the pros and cons of lithium vs. lead-acid?

Lithium batteries offer 2x lifespan and 50% weight savings but cost 3x upfront. Lead-acid remains cheaper for low-use scenarios. Pro Tip: Lithium’s flat discharge curve maintains speed consistency, unlike lead-acid’s voltage drop.

LiFePO4 cells deliver 2,000–5,000 cycles vs. 300–500 for lead-acid. A 48V 100Ah lithium pack weighs 55 lbs, while lead-acid equivalents exceed 150 lbs. But what about cold weather? Lithium performs better below 32°F, retaining 85% capacity vs. 50% for lead-acid. However, lithium requires a BMS—a $100–$300 added cost. Transitionally, for daily-use carts, lithium’s ROI is clear. For example, a golf course saving $200/year on maintenance breaks even in 5 years. Yet, lead-acid still dominates budget retrofits.

How does voltage affect golf cart performance?

Voltage directly influences speed and torque. Higher voltage increases motor RPM (speed) and reduces current draw for the same power. Pro Tip: Upgrading from 36V to 48V can boost hill-climbing ability by 30% without motor changes.

Ohm’s Law (Power = Voltage × Current) explains this: a 48V system at 50A delivers 2.4kW, whereas 36V needs 66.7A for the same power. Higher current heats cables and drains batteries faster. For example, a 48V cart accelerates faster from 0–15 mph than 36V, crucial for uphill starts. But voltage alone isn’t everything—controller programming matters. Transitionally, mismatched voltage and motor KV ratings cause inefficiency. Always test voltage under load—a “72V” battery sagging to 68V under strain negates benefits.

How Long Can a Golf Cart Sit Unused?

Can you upgrade a golf cart’s battery voltage?

Yes, but it requires controller and motor compatibility checks. Swapping 36V to 48V often works with existing motors, but 72V usually needs component upgrades. Pro Tip: After voltage upgrades, recalibrate the speedometer—the cart may exceed factory limits.

Upgrading from 36V to 48V involves adding two more 6V lead-acid batteries or reconfiguring lithium modules. However, the motor’s insulation must handle higher voltage—36V motors on 48V risk overheating. For example, a 36V motor rated for 48V (if compatible) gains 33% more RPM. Practically speaking, lithium conversions simplify upgrades—modular packs allow voltage adjustments. But don’t overlook the charger: a 48V system needs a 54.6V (lead-acid) or 58.4V (LiFePO4) charger. Transitionally, consult wiring diagrams—double-check solenoid and FNR switch ratings.
