12V Lithium Battery · LiFePO4 · Bluetooth
The ALPHA 2 is Rich Solar's core 12V 200Ah LiFePO4 battery — rated for 5,000+ cycles with Bluetooth real-time monitoring and internal self-heating for cold-weather charging, sized for RVs, trailers, vans, boats, and off-grid use.
The ALPHA 2 is the standard model in Rich Solar's ALPHA 2 series, built around a 12.8V 200Ah LiFePO4 pack rated for 5,000+ charge cycles. It includes both Bluetooth real-time monitoring and internal self-heating technology — the same core feature set as the ALPHA 2 PRO, without the PRO's higher cycle rating and 200A charge/discharge ceiling.
It's built for anyone who wants dependable, connected power for an RV, trailer, van, or boat, with the option to step up to the ALPHA 2 PRO for higher continuous current or step down to the ALPHA 2 LITE for a simpler, more affordable pack.

All three share the same 12V 200Ah LiFePO4 chemistry. The standard ALPHA 2 includes Bluetooth monitoring and self-heating (which the LITE lacks), but has a lower 100A max charge/discharge current and 5,000+ cycle rating compared to the PRO's 200A and 7,000+ cycles.
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 self-heating is built in, with charging current also automatically reduced at low and high temperature extremes to protect the cells.
Yes — maximum charging current varies by battery temperature, from 30A near freezing, up to 100A in the 68°F–104°F range, then back down to 30A above 104°F.
