TITAN-2 Battery Packs Family

The TITAN-2 Battery pack family is a Small Satellite format power storage and delivery system designed to provide the highest energy capacity and redundancy. It integrates fast onboard redundant charging circuitry, automatic heating system and temperature sensor in a single unit from a minimum of 400 W/hr to 8000 W/hr.

For missions from Small Satellites to larger spacecraft like Space Tugs, Launch Vehicles, or even Lunar rovers too, TITAN-2 enables a high energy density, low volume and mass solution for a modular, scalable approach to high power requirements missions.


The TITAN2 family is fully customizable to your mission’s need in terms of power delivery, power density, output power, cable, connectors or interfaces and options are available as integrated Carbon Nanotubes Thermal Transfer Bus (CN/TTB) shield which allows missions to reuse the spacecraft self-generated heat.

TITAN-2 is based on our exclusive PowerFlex technology, which allows the user to generate up to double the nominal power of the PCDU in case of peak demand for long periods of time: This means that if you have payloads that require huge loads for a short period of time, you don’t need to dimension the whole battery array for it, TITAN-2 can rush up to 2 times the power surge needed and serve those needs safely and under some conditions, up to 4 times.
