Summary

The Linear EPS is provides regulated +5V and +3.3V power and unregulated battery power (6 - 8.2Vdc) to modules compatible with the CubeSat Kit Bus from two (normal-capacity configuration) or four (high-capacity configuration) 3.7V Li-Po cells. Each cell is a standard 1st- and 2nd-generation iPodÆ battery. Each battery consists of two cells, operated in series when discharging (i.e., supplying power to the CubeSat Kit bus) and in parallel when charging. Up to two batteries can be operated in parallel. Non-latching relays are used to switch the cells between the series and parallel configurations. Two independent battery chargers each charge one cell (normal-capacity configuration) or two parallel-connected cells (high-capacity configuration) when operating in the charging mode.
