No. LiFePO4 batteries require a lithium-compatible charger with a 58.4V charge profile. Using a lead-acid charger will damage the battery and void the warranty. Will this work without reprogramming my controller? In most cases, yes. Factory 48V controllers are generally compatible. 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 3,000–5,000 cycles. At typical golf cart usage, that translates to 10+ years of service life. Does this include a charger or cables? No — this is a standalone battery. See our vehicle-specific conversion kits or battery bundles for complete packages with charger, cables, and SOC gauge. 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.
