Integrated 3 to 6 cell Li-Ion Battery System

Space Inventor

The BAT-6 is a 3 to 6 cell Lithium-Ion battery system
designed for battery life-time, easy integration, and safety.
With a total of 8 different battery configurations and up to
59 Wh capacity, the BAT-6 is both flexible enough and
sufficiently powerful for most nano- and small-satellite
The automatic balancing circuit maximizes battery lifetime,
and the automatic heater ensures optimal operational
battery environment at all times. Short-circuit and
over/under voltage detection circuits protects the batteries
from damage. To accommodate different launch vehicle
requirements, each module has connectors for both soft
and hard inhibits.
The BAT-6 comes in a rugged and modular 1.5 mm Al
enclosure, which both acts as on-orbit radiation mitigation
as well as a practical short-circuit protection during
satellite assembly.
An always-on ultra-low-power Real Time Clock provides
timer-continuity during satellite shutdown.
