12V Lithium Battery · LiFePO4 · PRO
The ALPHA 2 PRO is Rich Solar's top-tier 12V 200Ah LiFePO4 battery — rated for 7,000+ cycles with a 10-year warranty, Bluetooth real-time monitoring, and internal self-heating for cold-weather charging, built for RVs, cabins, and tiny homes.
The ALPHA 2 PRO sits at the top of Rich Solar's ALPHA 2 lineup, built around industrial-grade cells, a sophisticated battery management system, and a 12.8V 200Ah pack rated for over 7,000 charge cycles. It's certified to ANSI/CAN/UL 1973 and backed by ETL certification, aimed at RVs, cabins, and tiny homes that need a battery built to be trusted, not babysat.
Real-time Bluetooth monitoring reports the battery's status directly to a mobile device, while built-in internal heating keeps charging safe when temperatures drop — two features that set the PRO apart from the standard ALPHA 2 and ALPHA 2 LITE in the same lineup.
