Which Capacity Is Right for You? Capacity Energy Range Best For 51V 105Ah 5.38 kWh 25–35 mi Daily driving, golf, errands ✅ Most popular 51V 168Ah 8.60 kWh Up to 50 mi Heavy loads, hills, all-day use 51V 210Ah 10.75 kWh Up to 65 mi Maximum range, commercial/fleet use Frequently Asked Questions Does this include a charger? Yes — the bundle includes a CH5618 58.4V 18A LiFePO4 Smart Charger, cable set, AC power connector, and SOC gauge. Everything you need for a complete installation. Will this work without reprogramming my controller? In most cases, yes. Factory 48V controllers are generally compatible with 51.2V lithium. If your vehicle uses a Curtis or GE controller with custom programming, verify settings against the 51.2V nominal voltage. How long will this battery last? LiFePO4 cells are rated for 5,000+ cycles. At typical golf cart usage, that translates to 10+ years of service life — backed by our 10-year warranty. Does it work in cold weather? Yes. The built-in heater activates automatically when charging below 32°F, protecting the cells. This is standard — not a paid upgrade like many competitors charge $200–$400 for. What does the Bluetooth BMS monitor? Real-time cell voltages, pack temperature, state of charge, cycle count, and fault codes — all from the Fleet Lithium app on your phone. Range estimates depend on terrain, payload, speed, temperature, and driving habits.
