Compact 12 V LiFePO4 power

The BatteryJack Banshee is a 12.8 V 7 Ah lithium iron phosphate battery weighing 2.09 lbs and measuring 151 × 65 × 100 mm. It supplies 89.6 Wh in a single F2-terminal pack built for portable and stationary use.

Direct SLA replacement

It replaces 12 V 7 Ah sealed lead-acid units such as the Ritar RT1270, delivering twice the usable capacity at 60 % of the weight. The jump is worth it when cycle life matters: rated for 3000-plus cycles at 1 C and 100 % depth of discharge versus a few hundred for SLA.

7 Ah capacity and series headroom

The 7 Ah pack comfortably runs fish finders, flashers, robotics, solar lighting, e-scooters and alarm systems for extended periods. Up to four units can be paralleled for more runtime or placed in series for higher voltage, but a single pack cannot exceed its 7 Ah rating.

Questions about this item

Will the 151 × 65 × 100 mm case and F2 terminals fit my existing SLA 12V 7Ah tray?

The battery measures 151 mm long, 65 mm wide and 100 mm high with F2 terminals, matching the standard footprint of a 12 V 7 Ah SLA such as the Ritar RT1270.

What is the correct way to connect the F2 terminals during installation, and what mistake should I avoid?

Connect the red lead to the positive F2 tab and the black lead to the negative tab; the common error is reversing the polarity, which can trigger the internal BMS protection.

After roughly 3000 cycles at 100 % depth of discharge, what part of the battery will need replacement?

The entire 12.8 V 7 Ah LiFePO4 pack is a sealed unit; once cycle life is reached the whole battery must be replaced.
