B14-M45/M90 14V Modular SmallSat Battery
Radiation-tolerant 14V modular Li-ion SmallSat battery: 45 Whr single module (B14-M45) or 90 Whr dual module (B14-M90), 6.5A peak discharge, 30 kRad TID, TRL 9.
Description
The Ibeos B14-M45/M90 is a radiation-tolerant, fault-tolerant, ISS-compliant 14V lithium-ion battery module for small satellites. The single-module B14-M45 delivers 45 Whr capacity; two modules integrated side-by-side form the B14-M90 at 90 Whr. Aluminum and PEEK packaging provides structural integrity and thermal management. The Battery Interface Electronics (BIE) provides remove-before-flight inhibit, over-voltage protection (OVP), over-current protection (OCP), and under-voltage protection (UVP). Compatible with the Ibeos E14-150 Electric Power System for a complete 14V power chain.
