About
The Ibeos B28-M275/550/825/1100 is a radiation-tolerant, fault-tolerant modular 28V lithium-ion battery series for SmallSat and larger spacecraft. Four configurations cover 275 to 1100 Whr in 275 Whr increments. Aluminum and PEEK chassis with Kapton thermofoil heaters. Connectors are 1x 100-pin 38999 plus 1x 21-pin Micro-D. Discharge rates scale with capacity from 20A (275 Whr) to 80A (1100 Whr). Mass ranges from 2.1 kg to 7.8 kg and length from 150 mm to 465 mm, with constant 147×90 mm cross-section for modular integration.
