The 36V GC2 lithium-ion battery is engineered for powering low-speed electric vehicles like golf carts and mobility scooters, providing high-capacity energy storage with integrated battery management systems (BMS) for enhanced safety. It uses lithium iron phosphate (LiFePO4) chemistry for stable performance in frequent start-stop cycles, delivering 36V nominal voltage and capacities up to 105Ah. Designed to replace legacy lead-acid batteries, it offers 2,000+ cycles at 80% depth of discharge (DoD), making it ideal for applications requiring sustained runtime and durability.

What distinguishes the GC2 36V battery from standard lithium batteries?
The GC2 36V battery features built-in BMS protection, LiFePO4 chemistry, and high-cycle durability tailored for low-speed EVs. Unlike generic lithium packs, it prioritizes thermal stability and load surge tolerance in stop-and-go operations.

This battery’s design centers on golf cart requirements—imagine climbing a 15° hill repeatedly without voltage sag. Its BMS monitors cell balance, temperature, and current, shutting down during overloads (e.g., >100A continuous). Pro Tip: Always check the BMS communication protocol compatibility with your vehicle’s controller—mismatches can trigger false faults. Compared to standard NMC batteries, LiFePO4 in the GC2 offers 3x cycle life but slightly lower energy density. For example, a 36V 105Ah GC2 pack provides 3.78kWh, powering an average golf cart for 30–40 km per charge. But why prioritize cycle life over energy density here? Frequent partial discharges in carts demand longevity, not maximum range.
| Feature | GC2 36V | Standard 36V Li-ion |
|---|---|---|
| Cycle Life (80% DoD) | 2,000+ | 500–800 |
| Peak Current | 150A (5s) | 100A (3s) |
Why is LiFePO4 preferred for GC2 36V batteries?
LiFePO4 provides thermal runaway resistance, flat discharge curves, and safer failure modes compared to NMC/LCO cells, crucial for passenger-carrying EVs. Its 3.2V nominal cell voltage allows 12S configurations to hit 38.4V fully charged—within golf cart motor tolerances.

In real-world terms, LiFePO4 maintains 90% capacity after 1,500 cycles vs. NMC’s 60%—critical when replacing batteries costs $1,500+ per vehicle. Charging is simpler too: a GC2 battery accepts 2A–20A inputs without cell imbalance issues common in NMC packs. Practically speaking, carts often operate in 0°C–45°C environments where LiFePO4 excels, whereas NMC struggles below -10°C. Pro Tip: Use temperature-compensated charging—reduce voltage by 3mV/°C when ambient exceeds 25°C. Ever wonder why golf cart makers avoid ultra-high-energy cells? Safety trumps density when transporting people at 25 km/h.
How does the GC2 36V battery handle frequent partial discharges?
The GC2 employs adaptive BMS algorithms and low self-discharge LiFePO4 to manage shallow cycling. Partial discharges under 50% DoD minimally degrade capacity, unlike lead-acid batteries suffering sulfation.
Consider a golf cart used for 10 short trips daily: the GC2 might cycle 20% DoD each time, accumulating 1,000+ cycles annually. Lead-acid would fail within 18 months, while the GC2 lasts 5+ years. The BMS also prevents damage from micro-cycles—tiny charge/discharge pulses during idle periods. For example, a parked cart with activated GPS tracking drains 0.5Ah daily; the BMS disconnects loads at 20% SOC to preserve cell health. But what if users forget to recharge for weeks? LiFePO4’s 3% monthly self-discharge vs. lead-acid’s 15% makes the GC2 far more forgiving.
| Parameter | GC2 36V | Lead-Acid 36V |
|---|---|---|
| DoD Tolerance | 80% recommended | 50% max |
| Idle Self-Discharge | 3%/month | 15%/month |

FAQs
Yes, but verify the tray dimensions—GC2 units are 30% smaller than three 12V lead-acid batteries. Rewiring may be needed to bypass voltage converters.
Is the GC2 compatible with regenerative braking systems?
Only if the BMS supports bidirectional current. Our GC2 Pro models include 50A regen acceptance; standard units limit charging to 20A.
