Details
Built for reliable clean-energy storage, this 12.8V 200Ah LiFePO4 battery suits RVs, vans, golf carts, UPS systems, and solar setups.
Fast-charging support helps reduce downtime, with up to 200A charging current and a recommended 0.5C (100A) rate for longevity.
An integrated BMS provides comprehensive protection against common electrical and thermal faults.
Typical runtime examples help estimate usage for everyday loads like TVs, refrigerators, microwaves, and lighting.
Higher charging current can significantly shorten recharge time when your charger and system are sized accordingly.
Long service life is supported by 6000+ cycle capability, a 10-year design life, and a 5-year warranty.
A practical drop-in alternative for upgrading 12V lead-acid battery banks in mobile and off-grid power systems.
Well-suited for 12V golf cart upgrades where lighter weight, faster charging, and built-in protection are priorities.
Ideal for photovoltaic energy storage to help increase self-consumption and reduce reliance on grid power.
System expansion supports up to 4 in series and 4 in parallel for higher-voltage, higher-capacity battery banks.
