Description
Overview
The ALPHA 3 family packs about 3.8 to 4kWh into a single 12V battery, so one battery can do the work of three 100Ah batteries. All versions use Grade A+ LiFePO4 cells, an IP65 housing with a UL94 V-0 flame-retardant shell, and connect up to four in parallel.
The LITE is the value pick without heating or Bluetooth. The ALPHA 3 adds internal heating and Bluetooth. The PRO has the longest cycle rating and UL 1973 certification. The MINI is about 40% smaller in volume than standard 12V 314Ah batteries.
Who it’s for
- RVs and vans that need a lot of 12V storage.
- Off-grid cabins.
- Home backup systems on a 12V inverter.
Key benefits
- Huge 12V capacity: up to 4,019Wh per battery.
- Four versions: pick the features you need.

Why do the PRO and MINI say 314Ah?
That’s Rich Solar’s current rating for those versions, which uses larger 314Ah cells.
