About
The Ibeos B50-412/825/1237 is a radiation-tolerant, fault-tolerant modular 50V lithium-ion battery series for spacecraft requiring 50V power buses. Three configurations cover 412 to 1237 Whr. 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 (412 Whr) to 60A (1237 Whr). Mass ranges from 3.0 kg to 8.8 kg, with constant 147×90 mm cross-section for modular integration. This series supersedes the earlier B50-1000 design.
