ALPHA 3 PRO – 12V 314Ah LiFePO4 Battery
SKU:RS-B123SP
Product Information
12V 314Ah LiFePO4 Battery for Off-Grid, RV and Marine Systems
4.02kWh of lithium iron phosphate storage in a single case. LiFePO₄ cells hold a flat voltage through most of the discharge, so lights do not dim and inverters do not cut out early the way they do on lead-acid.
Rated for 8,000+ cycles, LiFePO4 can be discharged far deeper than lead-acid without damage, so more of the rated capacity is actually usable — and there is no watering, venting or equalising to keep up with. Up to 4 units (4P) in parallel.
A built-in heater lets it charge below freezing, which ordinary lithium cannot do safely. Bluetooth shows state of charge, current and cell health on your phone. Continuous discharge up to 200A. Backed by a 10-year warranty.
