The Ibeos B50-1237 50V Modular Battery is radiation- and fault-tolerant, and features rigid, thermally-conductive aluminium and PEEK packaging.

The battery is suitable for flexible thermal and mechanical spacecraft interfacing and has external surfaces treated with MIL-DTL-5541 Type II Class 3 chem film.

Polyimide thermofoil heaters are incorporated, along with thermistors, for enhanced thermal control.

Over-voltage, under-voltage, and over-current protection is included, along with radiation-tolerant battery interface electronics (BIE) that provide a remove-before-flight inhibit.
