Power solar arrays, RV house systems, trolling motors, and off-grid cabins with this 2-pack of 12V 280Ah deep-cycle LiFePO4 batteries. Each Grade-A pack delivers 4,000 to 15,000 deep cycles with over 80% depth of discharge after 4,000 cycles, 80A max charging, and 150A max discharge. A built-in smart BMS guards against overcharge, overcurrent, over-discharge, short circuits, and high temperatures, while low-temp protection halts discharge below 5°F and charging below 14°F. T14 terminals connect quickly to RVs, boats, solar inverters, and home storage. Series and parallel up to 16 batteries.
12V 280Ah Deep Cycle Capacity: Two 12.8V 280Ah Grade-A LiFePO4 packs deliver 4,000 to 15,000 deep cycles with 80% DOD after 4,000 cycles for solar storage
Smart BMS Multi-Layer Protection: Built-in smart BMS guards against overcharge, overcurrent, over-discharge, short circuits, and high temperatures across both packs
Low-Temp Charge Cutoff: Pack stops discharging below 5°F and charging below 14°F so cells stay safe through cold winter overnight runs in RVs, boats, and cabins
T14 Terminals for Solar and RV: T14 standard terminals connect quickly to RVs, boats, trolling motors, solar inverters, and same-brand parallel up to 16 packs
Lead-Acid Replacement Build: At 113.54 lb each, the LiFePO4 battery doubles capacity of typical lead-acid blocks for a lighter single-unit upgrade with 10-year service
