12V Lithium Battery · LiFePO4 · 200Ah
The ALPHA 2 LITE is Rich Solar's value-focused 12V 200Ah LiFePO4 battery — rated for 4,000+ cycles, built with individually fused cells and a sophisticated BMS, sized for RVs, trailers, vans, boats, and off-grid use.
For adventurers and off-gridders looking for durable, powerful energy storage, the ALPHA 2 LITE is a 12V 200Ah LiFePO4 battery built to provide reliable energy. Its durable construction and individually fused LiFePO4 cells provide excessive heat protection, short-circuit protection, and individual cell failure protection.
With 2,560Wh of capacity and a BMS system designed for optimal protection, it's built to keep running whether it's set up as backup power at home or boondocking off-grid — giving you the freedom to go where you want without worrying about running out of energy.

All three share the same 12V 200Ah LiFePO4 chemistry. The LITE is the value-focused entry point in the lineup — the ALPHA 2 PRO adds Bluetooth monitoring, internal self-heating, and a higher 7,000+ cycle rating, which the LITE does not include.
Each lithium cell in the pack has its own fuse, so if a single cell develops a fault, it's isolated rather than affecting the rest of the battery.
No — those features are specific to the ALPHA 2 PRO. The ALPHA 2 LITE focuses on core reliability: a sophisticated BMS, individually fused cells, and IP55-rated protection.
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.
Rich Solar's product page for this battery doesn't list a specific warranty term — check their warranty page or contact their support team directly for current coverage details.
The battery was shipped and arrived in a timely fashion, arriving the day that was predicted. The battery was installed and is operating as expected. My only concern is that I could possibly have fed the dragon, as I’m not sure where this battery was manufactured. The outside of the shipping container does not provide any country of origin information therefore I cannot give it any greater than a 3 star rating.
