Answers about lead-acid replacement, system compatibility, OEM battery development, certifications and wholesale orders.
Can LiFePO4 batteries replace lead-acid batteries?
Many LiFePO4 batteries can replace compatible lead-acid deep-cycle batteries in RVs, boats, golf carts and industrial equipment. Before installation, confirm the system voltage, battery dimensions, terminal layout, charger profile, maximum load, cable size, fuse rating and operating temperature.
Are LiFePO4 batteries compatible with existing chargers and inverters?
Most LiFePO4 batteries are compatible with standard 12V, 24V, 36V or 48V inverters when the system voltage and power requirements match. Many modern chargers also include a LiFePO4 charging profile. For lead-acid replacement projects, confirm the charger voltage, inverter rating and maximum load before installation. A compatible charger or DC-to-DC charger may be required if the existing charging equipment does not support LiFePO4 batteries.
