BAT-110 image


The BST BAT-110 is a modular battery system for small satellites. It is the successor of the flight proven battery pack that has been developed for the Kent Ridge-1 satellite. It is based on Li-Fe cells. The BST’s Li-Fe battery technology offers 10x more cycle over Li-Io or Li-Po batteries and is significantly less hazardous. The battery block is protected for over charging (non-destructive), tolerant against deep discharge (non-destructive) and offers cell balancing. It is space proven and has a design life of 5 years in LEO. The BAT-110 consists out of 3 strings in parallel each with a nominal capacity of 2.5 Ah. The electrical interface is a 15pin D-SUB female connector.
