Upgrade from Trojan: Lithium Golf Cart Battery Replacements for Bulk Buyers
Upgrading from Trojan lead-acid to lithium batteries offers bulk buyers a 70% reduction in weight, 3x longer cycle life (2,000–5,000 cycles), and 95% usable capacity versus 50% in lead-acid. Lithium iron phosphate (LiFePO4) cells provide maintenance-free operation, faster charging (1–3 hours), and 30% higher energy density. Redway’s direct replacement kits ensure compatibility with Club Car, EZGO, and Yamaha carts, reducing downtime during fleet transitions.

Why should bulk buyers switch from Trojan to lithium?
Lithium batteries eliminate sulfate degradation and water refills while delivering consistent voltage. Fleet operators save $2,100–$3,800 per cart over 5 years through reduced replacement frequency and downtime. Redway’s 72V 105Ah LiFePO4 pack weighs 64 lbs vs. Trojan T-875’s 140 lbs, enabling longer single-charge shifts. Pro Tip: Always verify motor controller compatibility—lithium’s flat discharge curve may require voltage calibration.
How to choose the right lithium battery for fleet carts?
Match Trojan’s footprint with IP67-rated LiFePO4 packs using marine-grade aluminum housings. Prioritize 100A continuous discharge for hilly terrains. Redway’s RLFP-72V-120A offers 120Ah capacity with built-in Bluetooth BMS monitoring 20+ parameters. For extreme cold (-20°C), select packs with self-heating cells. Remember, lithium’s 2V higher resting voltage may require charger adjustments to avoid undercharging.
What’s the cost difference over 10 years?
Lithium’s upfront cost is 2.5x higher but yields 65% lower TCO. For 50 carts, Trojan T-875s cost $72,500 initially versus $125,000 for lithium. However, factoring in 3x lead-acid replacements and labor, lithium saves $58K+ by year 10. Fast charging also reduces energy waste—lithium achieves 99% charge efficiency versus 80% in lead-acid.
| Cost Factor | Trojan Lead-Acid | LiFePO4 |
|---|---|---|
| 10-Year Replacement Cycles | 3 | 0 |
| Labor Hours/Cart/Year | 8 | 0.5 |
| Avg. Energy Cost/Mile | $0.12 | $0.07 |
Are lithium batteries compatible with older golf carts?
Most 2000+ models with 48V–72V systems support drop-in lithium upgrades if the BMS includes pre-charge circuits. For EZGO TXT series, confirm solenoid compatibility—lithium’s low internal resistance may require HD contactors. Redway provides plug-and-play adapters for 1994–2023 Club Car DS/Precedent. Surprisingly, lithium works better with older resistorspeed controllers than new PM motors due to stable voltage delivery.
What warranty terms matter for bulk purchases?
Demand prorated 7–10 year warranties covering 80% capacity retention. Redway offers 120-month coverage with free cell matching services. For fleets, negotiate cycle-based warranties (e.g., 4,000 cycles/8 years). Avoid suppliers without thermal abuse testing certs—UL1973 and UN38.3 are non-negotiable. Always audit 3rd party test reports—reputable brands share detailed cycle data across DoD ranges.
| Warranty Aspect | Typical Lead-Acid | Premium Lithium |
|---|---|---|
| Coverage Period | 1 Year | 7–10 Years |
| Depth of Discharge | 50% | 100% |
| Capacity Threshold | N/A | 80% |
How do lithium batteries perform in extreme temperatures?
LiFePO4 operates from -20°C to 60°C with active thermal management. At -10°C, capacity drops to 85% but recovers fully when warmed. Redway’s Arctic Series uses ceramic heaters maintaining 5°C minimum cell temp. In contrast, lead-acid loses 40% capacity below freezing and risks plate cracking. Pro Tip: Store lithium at 50% SoC in prolonged storage to minimize calendar aging.

FAQs
No—lithium requires CC-CV chargers with voltage accuracy ±0.5%. Trojan’s lead-acid chargers overcharge lithium to 90% SoC, causing cell imbalance. Redway’s 15A/30A smart chargers include temperature compensation.
Do lithium batteries need special disposal?
LiFePO4 is non-toxic and 98% recyclable. Redway partners with certified e-waste centers for free bulk recycling—unlike lead-acid’s $15–$25/cart hazmat fees.
How fast can you ship 100+ units?
Pre-built 72V packs ship globally in 5–7 days. Custom voltages/connectors require 14-day lead time. All bulk orders include spare mounting hardware and CANbus cables.
What’s the minimum order quantity?
MOQ is 10 units for custom BMS programming. Standard kits ship single units. For 50+ orders, request factory-direct pricing with volume discounts up to 22%.
Are your batteries DOT/IATA certified?
Yes—all Redway lithium packs meet Class 9 hazardous materials transport requirements. We handle FAA paperwork for air freight, unlike most lead-acid suppliers.
