The Powerbank 4 is hand made by Space Inventor

using LiIon cells with nearly

two decades of heritage in nano satellites.

All cells are screened and matched

before re-wrapping and integration in the

aluminium enclosure.

The Powerbank 4 battery system uses Space Inventor’s well-established form-factor and is designed to stack with Powerplant 6U. The hi-rel chassis connectors allow the flexibility of disconnecting the battery or connecting external emulation or measurement instruments without disintegrating the spacecraft.
