What Are The Best Lithium Or Lead-Acid Golf Batteries?
Lithium iron phosphate (LiFePO4) batteries outperform lead-acid in golf carts due to 4× longer lifespan (up to 10 years), 50% weight reduction, and zero maintenance. Top options like LiTime 48V 100Ah and GLCE ENERGY 51.2V 105Ah deliver 40–47 miles per charge with 600A peak discharge. Lead-acid remains viable only for budget setups requiring low upfront costs, despite shorter 3–5 year lifespans and frequent watering needs.
Why choose LiFePO4 over lead-acid for golf carts?
LiFePO4 dominates with 15,000-cycle durability versus 500–1,000 cycles for lead-acid. Pro Tip: LiTime’s app-controlled BMS prevents over-discharge during steep climbs, extending pack life by 20% compared to basic lithium models.
Golf cart batteries face daily deep discharges that rapidly degrade lead-acid cells. A 51.2V 105Ah LiFePO4 pack provides 5.38kWh usable energy—double the capacity of lead-acid equivalents in half the weight. For example, GLCE ENERGY’s IP65-rated design eliminates acid spills during off-road use. Transitioning to lithium? Ensure your charger supports 51.2V±0.5V precision—mismatched voltages cause premature BMS shutdowns.
| Metric | LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 4,000–15,000 | 500–1,200 |
| Weight (48V 100Ah) | 50–60 lbs | 130–150 lbs |
| Peak Discharge | 600A | 300A |
What voltage/capacity suits most golf carts?
48V systems (51.2V lithium) balance power/range for 4-seaters. Sizes from 80Ah (25-mile range) to 150Ah (60+ miles) match usage patterns.

Standard 48V lithium packs replace 8×6V lead-acid batteries with 25% more usable capacity. A 100Ah LiTime unit supports 200A continuous draw—ideal for hilly courses drawing 150–180A during acceleration. For heavy loads (e.g., hunting carts with extra gear), opt for 105–150Ah models. Pro Tip: Calculate needed runtime: (Ah × 0.85 DoD) ÷ Avg current draw = hours. Example: 100Ah battery at 30A averages 2.8 hours (≈42 miles at 15mph).
How do lithium batteries enhance cart performance?
Voltage stability under load prevents speed drops—lithium maintains 51V at 200A vs. lead-acid’s 44V sag. This translates to 18–22% faster hill climbs.
Internal resistance under 25mΩ in LiFePO4 vs. 80mΩ+ in lead-acid reduces energy waste as heat. During 10-second 500A bursts (common when towing), lithium loses 8% efficiency versus 35% in flooded batteries. Upgraded controllers can leverage this: Club Car’s Navitas 600A kit paired with GLCE’s 51.2V 105Ah battery achieves 30mph versus stock 19mph. But remember—speed upgrades require upgraded brakes!
| Parameter | LiFePO4 | AGM |
|---|---|---|
| Charge Efficiency | 99% | 85% |
| Self-Discharge/Month | 3% | 15% |
| Operating Temp | -4°F to 140°F | 32°F to 113°F |

FAQs
Yes—lithium’s smaller size fits existing trays. Ensure the charger port matches your lithium’s voltage (e.g., 51.2V requires a 58.4V charger).
Do lithium batteries work in freezing temps?
Yes with heated models. Redway’s -40°F-rated packs use internal warmers drawing <8% capacity when active.
How long do lithium golf batteries last?
8–12 years with 80% capacity retention—charge after each use and avoid storing below 20% SOC.
