The battery pack powered Cosmoserve Space‘s experimental payload aboard Skyroot Aerospace‘s Vikram-1 ‘Aagaman’ mission. It operated at an altitude of 450 km, surviving launch vibrations, vacuum, radiation and extreme temperature swings before being validated as ‘space proven’.
The achievement is significant because flight heritage, or space-proven status, is considered the toughest qualification for space hardware. Batteries are among the most safety-critical components on a rocket, making flight heritage the first credential buyers typically look for.
“Every satellite mission lives or dies by its power system, which is why nobody wants to be the first to fly a new battery,” said Ronak Kumar Samantray, founder and CEO, TakeMe2Space. “Flying on the first private Indian rocket to reach orbit, and performing flawlessly at 450 km, is the strongest validation a product can earn. PowerBank-50 is now space proven, made in India and ready for every satellite builder in the world.”
PowerBank-50 stores more than 50 Wh of energy in a 380-gram package roughly the size of a paperback book. It uses high-energy-density lithium-ion cells, features an onboard battery management system and integrated cell heaters for operation in extreme cold, and can be stacked to power CubeSats and microsatellites with missions lasting up to five years in low-Earth orbit.
The company has priced the battery at Rs 1,04,900, positioning it as a lower-cost alternative to comparable imported products.
For India’s fast-growing small satellite ecosystem, the milestone allows developers to source a flight-proven battery pack domestically instead of relying on imported systems that are often costlier and involve longer procurement cycles.The company said the battery is already available off the shelf, making it easier for startups, universities and satellite manufacturers to access space-qualified power systems.
