Compact LiFePO4 power for portable gear

This 12.8V 7Ah lithium iron phosphate battery replaces UB1280 sealed lead-acid units in fish finders, flashers, robotics, solar lighting, e-scooters and home alarm systems. It delivers 89.6Wh of energy while weighing 2.09 lbs (0.95 kg), making it suited to hiking, camping and other outdoor activities where minimising weight is crucial.

F2 terminals and rugged cycle life

The F2 terminals provide a direct drop-in connection for existing UB1280 wiring, and the cell chemistry supports 3000+ charge-discharge cycles at 1C 100% depth of discharge. Dimensions of 5.94 x 2.56 x 3.94 in (151 x 65 x 100 mm) fit standard battery compartments, and up to four packs can be wired in parallel or in series for higher capacity or voltage.

Replaces SLA with twice the usable capacity

The pack offers 100% more usable capacity than an equivalent lead-acid battery at only 60% of the weight, so the upgrade is worth it when longer run-time and reduced mass matter. It is not for buyers who need more than 7Ah per module, systems that require terminals other than F2, or installations that exceed the four-unit series or parallel limit.

Questions about this item

What voltage does the 12.8V LiFePO4 chemistry actually deliver under load?

The nominal voltage is 12.8V and the energy rating is 89.6Wh, giving a steady 7Ah capacity across the discharge curve.

Will the F2 terminals and 151 × 65 × 100 mm case fit my existing UB1280 tray?

Yes, the battery measures 5.94 × 2.56 × 3.94 inches with standard F2 terminals, matching the UB1280 footprint.

How do I connect up to four packs in series without triggering the BMS?

Charge each unit to the same voltage first, then link positive to negative using the F2 terminals; the built-in BMS allows four in series.
