Long-Life Electrical Power System
Batteries are a central pain-point for mission lifetime in the nanosatellite sector. We have developed a unique battery architecture that resolves this. For an equivalent mass/volume to conventional lithium-ion architectures, our solution:
Increases operational lifetime typically 5X
Simplifies thermal/power management systems
Is inherently more robust, reliable, & flexible
Operates consistently over a wider temperature range
95%+ capacity retention at 1C after 25,000 cycles at 90% depth of discharge
This flight-qualified product is readily scalable from 36Wh-300Wh. The EPS is state-of-the-art with all required interfaces, sensors and safety features.
The examples below spell out the deltas one can expect.
