About
The Ibeos B28-135 is a 135 Whr radiation-tolerant, fault-protected 28V lithium-ion battery module for small satellites. Aluminum and PEEK chassis houses integrated thermistors and polyimide heaters for thermal management across the operating range. Provides 10A sustained discharge current and 2.5A recommended charge rate. The Battery Interface Electronics implements storage inhibit, OVP, OCP, and UVP. Mounts horizontally via rail or vertically via panel. Compatible with the Ibeos E28-200 Electric Power System.
