The BST BAT-110 is a modular battery system for small satellites based on Lithium-Ferrite (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 has a design life of 5 years lifetime in LEO (tested for > 3k cycles @ 0.5/1 C & 100% DoD) and its direct predecessor is space proven.
