Golf carts perform optimally with lithium-ion batteries, specifically LiFePO4 (Lithium Iron Phosphate), offering 2,000–5,000 cycles, 50% weight reduction over lead-acid, and stable 36V/48V/72V configurations. These batteries support fast charging (1–3 hours) and include built-in BMS for voltage/thermal protection. For hilly terrains, 48V 100Ah+ systems with 200A+ discharge currents are ideal.

What voltages suit different golf cart models?
36V, 48V, and 72V systems match cart size/load: 36V for light 2–4 seaters, 48V for moderate hills, and 72V for heavy-duty commercial use. For example, a 48V LiFePO4 pack often replaces 4x12V lead-acid batteries, saving 100+ lbs while boosting range by 25%.

Golf cart voltage needs depend on motor power and terrain. A 36V system (6x6V batteries) suits flat courses with 3–5 kW motors, while 48V (6x8V or 4x12V) handles 6–8 kW motors and moderate inclines. Pro Tip: Always check the motor’s voltage range—overvolting a 36V motor with 48V risks winding damage. For heavy loads, 72V systems (6x12V) paired with 10+ kW motors are optimal. Transitioning to lithium? A 48V 100Ah LiFePO4 pack delivers 5.12 kWh, enabling 35–50 miles per charge. For example, Club Car’s Onward LITHIUM model uses 48V for 100+ holes per charge. Beyond capacity, prioritize continuous discharge current—150A–300A ensures hill-climbing without voltage sag.
| Voltage | Lead-Acid Weight | LiFePO4 Weight |
|---|---|---|
| 36V | 290–340 lbs | 70–90 lbs |
| 48V | 380–480 lbs | 110–130 lbs |
| 72V | 580–720 lbs | 180–210 lbs |
Why choose LiFePO4 over lead-acid batteries?
LiFePO4 offers 4x longer lifespan, 80% depth of discharge, and 2–3x faster charging. Unlike lead-acid, lithium doesn’t sulfate, maintaining 90% capacity after 2,000 cycles. For instance, Trojan T-105 lead-acid lasts 500 cycles, while Redway’s 48V 100Ah LiFePO4 exceeds 3,000 cycles.

LiFePO4’s advantages start with energy density—120–160 Wh/kg versus 30–50 Wh/kg for lead-acid. Practically speaking, a 100Ah lithium pack occupies 60% less space, freeing up storage for accessories. Thermal stability is another key factor: LiFePO4 operates safely at -20°C to 60°C, whereas lead-acid loses 50% capacity below 0°C. But what about cost? Though lithium has 2x upfront cost, its 8–10-year lifespan beats lead-acid’s 2–3 years. For example, replacing $1,200 lead-acid batteries three times equals $3,600 vs. $2,500 for lithium. Pro Tip: Use lithium’s weight savings to increase payload—reducing 200 lbs improves acceleration by 15–20%.

FAQs
Yes, but verify voltage compatibility and charger specs. Redway’s drop-in 48V kits include adapters and BMS, avoiding controller modifications.
How often should I charge my LiFePO4 golf cart battery?
Charge after 80% discharge. Partial charges (20–80%) are safe and extend lifespan—unlike lead-acid, lithium doesn’t need full cycles.
