What this battery is and who it serves

This two-pack supplies 12.8 V, 7 Ah LiFePO4 cells weighing 0.95 kg each and measuring 151 × 65 × 100 mm with F2 terminals. They replace 12 V SLA units in stairlifts, alarm panels, solar lights, robotics, fish finders and e-scooters where light weight and long cycle life matter.

Who should choose it and who should not

Installers needing up to four packs in series or parallel for higher voltage or capacity will find the limit suitable. Buyers who require more than 89.6 Wh per block, a different terminal style, or a chemistry rated for fewer than 3,000 cycles at full depth of discharge should look elsewhere.

Capacity and headroom in daily use

Each pack delivers 89.6 Wh and sustains 1 C charge and discharge rates, giving ample runtime for portable instruments, backup power or light mobility duty. When loads exceed the 7 Ah rating or when more than four units are needed in a string, the available energy and connection limits are reached.

Questions about this item

What existing stairlift connector fits the F2 terminals on each Banshee pack?

The F2 terminals match the spade connectors used on Acorn Superglide models, so the original wiring plugs straight in.

Will the 151 × 65 × 100 mm case slide into the same battery tray as the old SLA unit?

Yes, the dimensions are a direct drop-in for the standard 12 V 7 Ah SLA tray used in those stairlifts.

How do I confirm the pack is delivering its rated 89.6 Wh after installation?

Measure 12.8 V at the terminals under load and verify the stairlift runs its normal cycle count without voltage sag.
