The 2GC-110 Golf Electric Vehicle Battery refers to a specialized 72V lithium-ion battery system designed for golf carts and utility vehicles. With a 110Ah capacity, it provides extended runtime and high discharge rates for demanding applications. These batteries typically use LiFePO4 chemistry for enhanced thermal stability and cycle life, achieving 2000+ cycles at 80% depth of discharge. Charging terminates at 84V (±1%) via CC-CV protocols to prevent overcharging, while integrated BMS protects against overcurrent and cell imbalance. Pro Tip: Always verify charger compatibility—mismatched voltage can trigger BMS shutdowns within 3-5 charge cycles.

What voltage range defines the 2GC-110 battery?
The 2GC-110 operates at a nominal 72V DC with 24 series LiFePO4 cells (3.2V/cell). Its working range spans 60V (20% SOC) to 84V (full charge). For example, golf carts using this battery maintain torque consistency even below 65V. Pro Tip: Monitor voltage sag during acceleration—sudden drops below 62V indicate aging cells needing replacement.

How does capacity affect golf cart performance?
The 110Ah rating enables 6-8 hours of continuous operation on hilly courses. Compared to standard 80Ah lead-acid equivalents, it reduces weight by 40% (from 540kg to 324kg) while doubling energy density. Real-world testing shows 22% faster hill climbs and 35% less voltage drop during sudden acceleration. Transitional phrase: Beyond raw power, the reduced weight…
| Parameter | 2GC-110 | Lead-Acid Equivalent |
|---|---|---|
| Cycle Life | 2000+ | 400 |
| Weight | 324kg | 540kg |
What thermal protections are implemented?
Multi-stage safeguards include PTC resettable fuses and ceramic-coated separators activating at 75°C. The aluminum casing provides IP67 waterproofing and dissipates heat 18% faster than steel enclosures. During desert testing, internal temperatures stayed below 55°C at 45°C ambient. Pro Tip: Avoid mounting near brake rotors—localized heat sources above 80°C accelerate electrolyte breakdown.

How does charging differ from standard EV batteries?
Utilizes modular balancing during charging—individual cell groups balance every 3 cycles via 500mA bleed resistors. Chargers deliver 30A standard (0.27C rate), completing full charges in 4.2 hours. Transitional phrase: Unlike automotive fast-charging systems…
| Charger Type | 2GC-110 | Automotive EV |
|---|---|---|
| Max Current | 30A | 150A+ |
| Balance Frequency | Every 3 cycles | Continuous |
What maintenance is required annually?
Requires torque checks on M8 terminal bolts every 500 cycles (14-17 N·m spec). Storage at 50% SOC with monthly 30-minute balance charges prevents cell drift. Transitional phrase: While maintenance is minimal compared to lead-acid…

FAQs
Only in 72V systems—check terminal polarity and tray dimensions. Most golf carts require upgraded 400A main circuit breakers for lithium’s lower internal resistance.
What’s the winter performance at -20°C?
Capacity drops to 78% of rated Ah without heating pads. Our optional self-warming version uses 150W silicon heaters, maintaining 85% capacity down to -30°C.
