Golf carts typically require deep-cycle batteries designed for sustained power delivery. Most carts use 6V, 8V, or 12V lead-acid batteries wired in series for 36V, 48V, or 72V systems. Modern upgrades favor lithium-ion (LiFePO4) batteries due to higher energy density, 2,000–5,000 cycles, and 30–50% weight savings. Key specs include voltage compatibility, Ah capacity (100–250Ah), and discharge rates (1C–3C).

What defines a golf cart battery system?
Golf cart batteries are defined by their voltage configuration and cycle durability. Series-wired 6V/8V lead-acid packs dominated older models, while newer lithium systems use modular 12V/24V LiFePO4 cells. For example, a 48V system requires four 12V lithium batteries or eight 6V lead-acid units. Pro Tip: Always match battery voltage to your cart’s motor controller—mismatches cause overheating or reduced torque.

Traditional flooded lead-acid (FLA) batteries offer 180–200 cycles at 50% depth of discharge (DoD), while lithium variants handle 80–90% DoD for 5x longer lifespan. Consider runtime needs: a 48V 100Ah lithium pack provides ~40 miles per charge versus 25 miles with lead-acid. But what if your cart has hydraulic brakes? Lithium’s instant current delivery improves stopping responsiveness. A 72V lithium system might even replace gas-powered carts for hilly terrains—just ensure the motor’s KV rating aligns with the voltage bump.
Lead-acid vs. lithium: Which is better for golf carts?
Lithium batteries outperform lead-acid in weight (70lbs vs. 180lbs), lifespan (10 vs. 3 years), and charge speed (2h vs. 8h). However, upfront lithium costs are 2–3x higher. Here’s a cost-per-cycle breakdown:

| Metric | Lead-Acid | Lithium |
|---|---|---|
| Cycle Life | 500 | 3,500 |
| Cost per Cycle | $0.18 | $0.04 |
| Weight (48V 100Ah) | 290 lbs | 110 lbs |
Practically speaking, lithium’s 30-minute fast-charge capability eliminates midday golf course waits. Imagine your cart feeling lighter—like swapping cinderblocks for a laptop bag. Still, budget-conscious users might tolerate lead-acid’s maintenance (watering, equalizing) for low-usage scenarios. But is it worth the labor? Lithium’s sealed design operates at any angle—perfect for rough terrain.
48V 100Ah LiFePO4 Golf Cart Battery
What factors determine golf cart battery capacity?
Battery capacity hinges on terrain, passenger load, and average trip length. A 48V 100Ah lithium battery delivers ~5kWh, sufficient for 40 miles on flat roads. Hilly courses demand 150Ah+ or higher discharge rates (2C). Pro Tip: Multiply your cart’s wattage by 1.2 to account for auxiliary loads like headlights or USB ports.
Consider voltage sag: lead-acid drops to 80% efficiency under heavy loads, while lithium holds 95%. If your cart struggles uphill, a high-current 160Ah lithium pack (like this model) maintains voltage stability. For example, a 4-passenger cart climbing 15% grades needs at least 200Ah lead-acid or 120Ah lithium. Always check the BMS (Battery Management System)—it prevents over-discharge below 20%, which is fatal to lead-acid cells.
How does temperature affect golf cart batteries?
Lithium batteries operate in -4°F to 140°F but lose 15–20% capacity below 32°F. Lead-acid suffers worse—50% capacity loss at 0°F. Hot climates (95°F+) accelerate lead-acid sulfation, reducing lifespan by 40%. Pro Tip: Store lithium packs at 50% charge in extreme heat to minimize electrolyte stress.
Ever left your cart unplugged in winter? Lithium’s low self-discharge (2% monthly) beats lead-acid’s 5–10%. For Arizona golfers, thermal runaway risks are higher with damaged lead-acid vents. Conversely, lithium’s solid-state LiFePO4 chemistry resists thermal events—even during fast charging. A built-in BMS with temperature cutoff (like Redway’s design) adds another safety layer.
| Condition | Lead-Acid | Lithium |
|---|---|---|
| 32°F Performance | 50% Capacity | 85% |
| 100°F Lifespan | 2 Years | 8–10 Years |
| Self-Discharge/Month | 5–10% | 1–3% |

FAQs
LiFePO4 lasts 3,000–5,000 cycles (8–10 years) vs. 500–800 for lead-acid. Properly maintained, they retain 80% capacity after a decade.
Can I convert my 36V cart to 48V lithium?
Yes, but upgrade the motor controller and wiring. A 48V system boosts torque by 33%—ideal for hilly terrain. Always consult a technician first.
