Compact lithium replacement

The BatteryJack inc. 12V 7Ah LiFePO4 unit replaces sealed lead-acid packs in fish finders, flashers, robotics, solar lighting, e-scooters and home alarm systems. It delivers 12.8V nominal voltage and 7Ah capacity for 89.6Wh of energy in a single 1-pack format. Weighing 2.09 lbs (0.95 kg), it is 60% the weight of an equivalent SLA battery while providing 100% more usable capacity.

Cycle life and configuration

The LiFePO4 chemistry supports 3000+ charge-discharge cycles at 1C and 100% depth of discharge, lasting roughly five times longer than traditional SLA alternatives. Up to four units can be wired in parallel for increased runtime or in series for higher voltage systems. Fast-charging capability reduces downtime in industrial or outdoor deployments where quick turnaround matters.

F2 terminals and rugged housing

F2 terminals provide a secure bolt-on connection that resists vibration in mobile or robotic use. The case measures 5.94 x 2.56 x 3.94 in (151 x 65 x 100 mm), fitting standard 12V 7Ah battery compartments without modification. Operation across extreme temperatures ensures reliable starts for camping, hiking or remote monitoring gear. Not suited for applications requiring integrated Bluetooth monitoring or proprietary charging protocols.
