BatteryJack inc. Banshee 12V 7Ah LiFePO4 Battery for APC Back-UPS ES 550VA

SKU CH-9BCT-8BT9R

A 12.8 V 7 Ah LiFePO4 pack delivers 89.6 Wh in a 151 × 65 × 100 mm case weighing 0.95 kg and rated for 3000-plus cycles

  • Battery Pack1-pack
  • Battery TypeLithium
  • 3000-plus charge cycles extend service life far beyond lead-acid
  • 6 Wh capacity at only 0.95 kg keeps gear light
  • 8 V nominal voltage matches APC Back-UPS ES 550VA requirements
  • F2 terminals allow direct drop-in installation
  • Up to four units in series or parallel for scalable power

Drop-in replacement for APC Back-UPS ES 550VA

This 12 V 7 Ah lithium iron phosphate battery fits the APC Back-UPS ES 550VA as a direct replacement for the original sealed lead-acid unit. It uses F2 terminals so the existing wiring connects without adapters. The pack weighs 2.09 lbs and measures 5.94 in by 2.56 in by 3.94 in, matching the standard footprint.

Sustained delivery over thousands of cycles

Rated at 12.8 V nominal and 89.6 Wh, the cell chemistry supports more than 3000 charge-discharge cycles at 1 C and 100 % depth of discharge. That cycle life is roughly five times longer than traditional SLA batteries while providing twice the usable capacity at only 60 % of the weight. The flat voltage curve keeps output stable through the full discharge.

Rugged build with flexible scaling

The hard-case construction and F2 terminals withstand vibration in robotics, e-scooters, fish finders and solar lighting. Up to four units can be wired in series for higher voltage or in parallel for greater capacity, allowing the same battery to serve home alarm backup, camping power or industrial equipment without changing hardware.

Questions about this item

How much heat does the 12.8 V 7 Ah LiFePO4 pack generate when running continuously in an APC Back-UPS ES 550VA?

LiFePO4 chemistry runs cooler than lead-acid equivalents; the 0.95 kg pack has no internal fan and relies on passive dissipation through the 151 × 65 × 100 mm case.

What existing UPS hardware is required for this F2-terminal battery to work?

The pack is a direct drop-in for the APC Back-UPS ES 550VA; you only need the UPS unit itself and its original wiring harness.

Will the 89.6 Wh lithium pack charge correctly on the older ES 550VA charger designed for sealed lead-acid?

The ES 550VA charger voltage profile is compatible with the 12.8 V nominal pack; no firmware change or external charger is needed.
