E-Z-GO golf carts typically use 48V lithium-ion batteries, though some models may employ 36V or 51.2V LiFePO4 systems. These batteries offer capacities ranging from 30Ah to 150Ah, optimized for deep-cycle performance and extended range. Key brands like JRE POWER and EXCAR provide variants with 6000+ cycle lifespans, integrated temperature protection, and customizations for EZGO club car compatibility. Charging voltages align with 48V (51.2V max) configurations for optimal energy delivery.
48V 100Ah LiFePO4 Golf Cart Battery
What voltage systems are common in E-Z-GO golf carts?
48V and 36V lithium batteries dominate modern E-Z-GO models. The 48V architecture balances power and range, while 36V systems suit lightweight applications. Advanced packs like 51.2V LiFePO4 ensure stable discharge curves even under hill climbs.

Most E-Z-GO carts manufactured post-2015 use 48V systems, which deliver 20% more torque than 36V counterparts. A 51.2V LiFePO4 battery, for example, maintains 48V nominal voltage but peaks at 51.2V when fully charged. Pro Tip: When replacing lead-acid batteries, match lithium pack voltages precisely—using a 36V lithium pack in a 48V cart risks permanent motor damage. Why does voltage matter? Higher voltages reduce current draw for equivalent power, minimizing heat buildup in wiring.
Which lithium chemistry works best for E-Z-GO carts?
LiFePO4 (LFP) dominates due to its thermal stability and 6000+ cycle lifespan. Unlike NMC batteries, LFP cells withstand golf cart vibration without performance drops.

LiFePO4’s flat discharge curve (3.2V per cell) ensures consistent speed during 18-hole rounds. A 48V 100Ah LFP pack provides 5.12kWh—enough for 30-45 miles per charge. Comparatively, lead-acid alternatives weigh 3× more and degrade after 500 cycles. For winter operation, LFP retains 85% capacity at -20°C versus NMC’s 50% drop. Pro Tip: Install battery heaters if operating below freezing—LFP charging below 0°C causes irreversible lithium plating.
| Chemistry | Cycle Life | Cold Performance |
|---|---|---|
| LiFePO4 | 6000+ | Moderate |
| NMC | 2000 | Poor |
How do capacity choices affect performance?
100Ah–150Ah batteries balance runtime and cost. Lower capacities (30Ah) work for short-range utility carts, while 150Ah units support all-day resort operations.
A 48V 105Ah battery delivers 5.3kWh—sufficient for 40 miles at 15mph. However, doubling capacity to 150Ah adds 50kg and requires chassis reinforcement. For hilly courses, prioritize high-current cells with 3C discharge rates. Did you know? Undersized batteries force frequent deep discharges, slashing lifespan by 40%. Always size packs for 20% daily depth-of-discharge (DoD) buffer.
| Capacity | Range | Ideal Use |
|---|---|---|
| 100Ah | 30mi | Personal carts |
| 150Ah | 45mi | Commercial fleets |

What customization options exist for E-Z-GO batteries?
Manufacturers offer BMS programming, Bluetooth monitoring, and form-factor adaptations. Custom cases ensure drop-in replacements for OEM lead-acid trays.
Advanced packs integrate CAN bus communication for real-time SOC tracking via mobile apps. Some models support dual-voltage outputs—e.g., 48V for propulsion plus 12V for accessories. Always request IP65-rated enclosures for dust/water resistance—essential for golf course maintenance vehicles. Pro Tip: Order batteries with threaded terminals instead of slip-on connectors—they withstand vibration 3× better.

FAQs
Yes, if voltage matches. Use adaptor plates for tray compatibility and update chargers to lithium-specific profiles to prevent overvoltage.
How long do lithium batteries last in E-Z-GO?
8–10 years with proper maintenance. Store at 50% SOC during offseason and avoid full discharges below 20%.
