BatteryJack inc. Banshee 12V 7Ah LiFePO4 Battery GS Portalac PX12072HG

Compact 12V 7Ah LiFePO4 Battery

The BatteryJack Banshee is a 12.8V nominal lithium iron phosphate battery rated at 7Ah and 89.6Wh. It replaces traditional 12V SLA units in applications such as fish finders, robotics, solar lighting, e-scooters and home alarm systems. The pack weighs 2.09 lbs (0.95 kg) and measures 5.94 x 2.56 x 3.94 in (151 x 65 x 100 mm). It is built for users who need long cycle life and reduced weight in a standard footprint.

Thermals Noise and Power Draw

LiFePO4 chemistry operates without active cooling, so the battery runs silently in normal use. It supports up to 3,000 charge cycles at 1C and 100% depth of discharge, far exceeding typical SLA endurance. The supplier notes it delivers twice the power of an equivalent lead-acid unit while maintaining high energy capacity. No moving parts mean zero acoustic output during charge or discharge.

Build Quality Connectors and Mounting

The case uses F2 terminals for straightforward drop-in replacement of existing 12V 7Ah SLA batteries. Up to four units can be wired in series or in parallel to scale voltage or capacity as needed. At 60% of the weight of a comparable SLA pack, it eases installation in portable gear such as hiking or camping kits. Buyers needing terminals other than F2 or a different form factor should verify compatibility before ordering.
