The Energy Company was started to solve a simple gap in energy storage: the need for reliable, high-quality, and smarter batteries. With Flexi, we’re building a full-stack battery platform that combines robust hardware with intelligent battery management for real-world use.

MARCH 2022

In just over three months, we launched the first iteration of FlexiPack: a fast-charging battery(12 min Charging)  compatible with any public charger, even at a 15-amp point, boasting twice the lifespan of other batteries on the market. Early adopters loved it!

We focused on making our batteries accessible to high performing use cases like last-mile deliveries. We introduced FlexiTwin, the digital brother of the FlexiPack, built on a unique framework- Battery Aadhaar. FlexiTwin provided advanced monitoring and analytics capabilities, enabling smarter battery management

JANUARY 2023

FlexiPack, now enhanced by FlexiTwin, transformed our battery’s digital identity. Our comprehensive life-cycle tests, conducted under real-world conditions, allowed us to optimise its performance to perfection.
