About

The ABSL CM2300 in 8s40p topology is a Li-ion space battery built on the ABSL P20 cell, configured for a 28 V spacecraft bus and delivering 2300 Wh of energy at 80 Ah nameplate capacity.

EnerSys batteries supply power for platform and payload systems and are also essential prior to the deployment of any solar array apparatus. Whether a short-term repositioning energy requirement or high current demand such as a pyrotechnic system actuation, the batteries meet the challenges of space flight with advanced high voltage, long-life Li-ion solutions.

ABSL batteries have logged over 6.5 billion cell hours in space without a mission failure.
