About
Enerstone supports the energy transition by increasing the lifespan of Lithium-ion batteries, therefore providing an alternative to their obsolescence. Enerstone’s Active Balancing products circuit helps battery manufacturers develop long lasting products for electric mobility as well as renewable energy storage systems.
Some key figures
The autonomy of a battery is limited by the weakest of its cells. At the end of its life, your battery is in fact more than 90% still operational! Enerstone restores the balance between the cells of your battery using a compact and innovative electronic circuit. Enerstone’s active balancer helps you benefit from the full capacity of your battery at every charge and extends its useful life by 34%, protecting your investment and the environment.
