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.

The PRO is the top tier of the lineup — it adds Bluetooth real-time monitoring, internal self-heating for cold-weather charging, and comes with a longer 10-year warranty.
Yes — maximum charging current varies by battery temperature, from 60A near freezing, up to 200A in the 68°F–104°F range, then back down to 60A above 104°F.
Real-time battery operation status reported to a mobile device via the built-in Bluetooth module, so the battery can be checked without a separate remote display.
Yes — internal heating activates automatically below 41°F and shuts off once the charger disconnects or the battery reaches 50°F, drawing 100W of power while active.
It's certified to ANSI/CAN/UL 1973 and carries ETL certification, with a UL94 V-0 flame-retardant plastic housing.
It's rated for 7,000+ charge cycles and backed by a 10-year warranty — longer than Rich Solar's 24V ALPHA batteries, which carry 5-year terms.
