ALPHA 4 – 24V 100Ah LiFePO4 Battery
SKU:RS-B241S
Product Information
24V 100Ah LiFePO4 Battery for Off-Grid, RV and Marine Systems
2.56kWh 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 5000+ 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. Backed by a 5-year warranty.
