12V 800Ah LiFePO4 Battery Bank – 10.24kWh
SKU:RS-B12800
Product Information
12V 800Ah Battery Bank for Off-Grid, RV and Marine Systems
This bank is 4 matched 12.8V 200Ah batteries supplied with the cables to join them, giving 10.24kWh of usable lithium storage in one order. Buying them matched avoids the commonest mistake in DIY banks: mixing cells of different age or capacity, which drags the whole bank down to the weakest unit.
Rated for 4,000+ 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.
Continuous discharge up to 200A. Backed by a 5-year warranty.
