Trojan Lithium-Ion batteries are high-performance energy solutions designed primarily for golf carts and electric vehicles. Utilizing LiFePO4 chemistry, they offer 45–60 miles per charge, 4-hour rapid charging, and 2–3 times longer lifespan than lead-acid alternatives. Their 48V GC2 models integrate UL/SAE-certified safety systems with rugged durability for off-road applications, while eliminating watering and acid leaks. Pro Tip: Always pair Trojan lithium packs with OEM-approved chargers to maintain warranty compliance.

What makes Trojan lithium batteries safer than lead-acid?
Trojan lithium batteries employ LiFePO4 chemistry with inherent thermal stability, reducing fire risks. They include multi-layer BMS protection against overcharge (≤84V cutoff) and cell imbalances. Unlike lead-acid systems, they produce no corrosive fumes during operation.

Beyond chemistry, Trojan’s design integrates Maxguard® separators and impact-resistant casings tested under SAE J2928 vibration standards. A real-world example: Their batteries withstand 1,500+ charge cycles at 80% depth-of-discharge (DoD) without capacity fade—triple lead-acid’s tolerance. Pro Tip: Avoid exposing terminals to metal tools; accidental short-circuits trigger BMS lockouts requiring professional reset.
How do Trojan lithium batteries extend vehicle range?
Higher energy density (38–40 Wh/kg) allows Trojan LiFePO4 packs to store 2× more usable energy than lead-acid equivalents. With 95% discharge capability vs. 50% for flooded batteries, they unlock full capacity without sulfation damage.

Practically speaking, a 48V 30Ah Trojan GC2 lithium system delivers 1.44kWh net energy—enough for 60 miles in standard golf carts. Comparatively, lead-acid setups require 8× 6V 225Ah batteries weighing 540 lbs to achieve similar range. The table below highlights efficiency gains:
| Metric | Trojan Lithium | Lead-Acid |
|---|---|---|
| Weight | 111 lbs | 540 lbs |
| Charge Cycles | 2,000+ | 600–800 |
Are Trojan lithium batteries compatible with all golf carts?
Trojan’s 48V GC2 series directly replaces 8×6V lead-acid configurations in Club Car, EZGO, and Yamaha models. However, EZGO RXV carts require three lithium batteries instead of two due to unique voltage regulation.
Why does compatibility vary? Some controllers interpret lithium’s flat voltage curve as “low charge,” triggering erroneous alerts. Trojan includes CANbus adapters in premium kits to resolve this. For older carts (pre-2010), consult Trojan’s compatibility portal—analog throttle systems may need voltage dividers. Pro Tip: Always verify pack voltage matches cart specifications; 48V systems demand ±2% voltage tolerance.
What maintenance do Trojan lithium batteries require?
Zero routine maintenance—no watering, terminal cleaning, or equalization charges needed. Built-in HydroLink™ monitoring tracks cell health automatically, with Bluetooth-enabled models offering real-time diagnostics via mobile apps.
But what about long-term storage? Store batteries at 50–60% charge in dry, 15–25°C environments. Unlike lead-acid types, lithium doesn’t sulfate when idle. A case study: Trojan lithium packs retained 97% capacity after 12 months of storage, versus 40% degradation in unmaintained lead-acid units. Warning: Avoid discharging below 10%—deep cycles below 42V accelerate aging.

FAQs
Yes—their low internal resistance (<25mΩ) sustains 300A peaks, delivering 20% more torque than lead-acid on 15° slopes. Ensure motor controllers support lithium’s current output.
Do Trojan batteries work in cold climates?
Operational from -20°C to 60°C, but charging below 0°C requires heated storage compartments to prevent lithium plating damage.
How does warranty coverage work?
12-month full replacement, prorated up to 10 years. Proof of professional installation and OEM charger use is mandatory for claims.
