What Is A Trojan Golf Cart Battery?
Trojan golf cart batteries are specialized energy storage units designed for electric golf carts, engineered to deliver sustained power and extended runtime. These batteries typically use lead-acid or lithium-ion chemistries, with Trojan’s OnePack Lithium series offering lightweight solutions (300+ lbs lighter than lead-acid) and high energy density. They provide reliable performance for steep terrain and long-distance use, such as the record-setting Pikes Peak ascent. Proper maintenance, including regular voltage checks (e.g., 48V systems monitored via 10–100V meters) and balanced charging, ensures longevity. Lithium variants reduce maintenance costs and improve handling due to reduced weight.
What defines a Trojan golf cart battery’s core technology?
Trojan batteries prioritize deep-cycle capabilities for repetitive discharge-recharge cycles. Lead-acid versions use thick plates for durability, while lithium-ion models (like OnePack) employ advanced BMS for thermal stability. Pro Tip: Always use a voltage meter (e.g., 12–84V DC) to monitor state of charge—critical for preventing sulfation in lead-acid units.
Trojan’s lead-acid batteries rely on robust plate design to withstand deep discharges, often achieving 1,000+ cycles at 50% depth of discharge (DoD). In contrast, their lithium-ion batteries, such as the OnePack, utilize LiFePO4 cells with 3,000–5,000 cycles at 80% DoD. For example, a 48V lithium Trojan system can power a golf cart for 35–50 miles per charge, outperforming lead-acid by 30%. Transitionally, lithium options eliminate acid leaks and water refills, streamlining maintenance. But why choose lead-acid? Initial cost: lithium packs cost 2–3x more upfront but save long-term via reduced replacements.
| Feature | Lead-Acid | Lithium-Ion |
|---|---|---|
| Cycle Life | 1,000 cycles | 3,000+ cycles |
| Weight | ~60 lbs per battery | ~30 lbs per battery |
| Maintenance | Monthly watering | None |
How do Trojan lithium batteries enhance golf cart performance?
Lithium-ion Trojan batteries reduce weight by 50% versus lead-acid, improving acceleration and hill-climbing. Their flat discharge curve maintains consistent speed even at low charge. Pro Tip: Pair with a compatible charger (e.g., 48V 20A) to avoid BMS tripping from voltage mismatches.
By shedding hundreds of pounds, Trojan’s lithium packs lower center of gravity, enhancing stability on slopes. A 48V 100Ah lithium battery delivers ~4.8kWh, enabling 4–6 hours of continuous use. Practically speaking, this means fewer mid-round slowdowns. For instance, a lithium-powered cart ascended Pikes Peak’s 14,115-foot summit without performance drops—a feat unachievable with lead-acid. Transitionally, lithium’s faster charging (4 hours vs. 8+ for lead-acid) minimizes downtime. However, can existing lead-acid carts upgrade to lithium? Yes, but controllers must support lithium’s voltage profile to prevent MOSFET damage.

FAQs
No. Mixing chemistries creates imbalance, leading to overcharging or undercharging. Stick to one type per system.
Do Trojan lithium batteries require cooling systems?
Not typically. Built-in BMS manages temperatures up to 113°F (45°C), but avoid direct sunlight exposure during charging.
