Say goodbye to disposable electric batteries!

We are building a battery which is feature-packed, easy to use and fully repairable.

The first battery made for humans and their planet!


As a developer, it's hard to be green. Batteries are routinely disposed of in waste because they cannot be repaired.

Our team set out to make an easy-to-use and eco-friendly power solution that is just as reliable and powerful as any off the market.

Now we have Gouach!

What sets Gouach apart is its innovative design which makes it robust and fully repairable. It is packed with features, customizable, and comes with an easy-to-use API, documentation, and friendly community.

Developers can implement new features fast and without any hassle. It doesn't matter if it's connecting the battery to the cloud, or optimizing power delivery — Gouach won't let them down.


Environmentally-friendly battery

A patented solder-less design which allows to repair the electronics and change the cells in less than 5 minutes. This reduces the CO2 footprint by 50%.

Fully repairable
The Gouach battery is designed to be fully repairable in less than 10 minutes. Stop throwing batteries. Give back power to the users, and to the planet.
Solder-less design
Using our solder-less design, the cells are attached securely and can be changed. Get a fresh battery, for a few dollars.
Reduced CO2 footprint
The Gouach repairable design allows up to 50% of CO2 reduction on the footprint of a battery.

Developer superpowers!

We believe that a battery should be feature-packed, easy to work with and customizable for your needs.

Get full BLE and WiFi connectivity without a new component. Our battery is even capable of passive SSID geolocation.
Sequential discharge
Using sequential discharge, you can link multiple batteries together to give more power to your product, while making it easy to swap batteries.
Smart charging
With smart-charging, your batteries can last up to 20% longer.

Fully customizable.

We offer custom form-factors to fit in any product. And make your work easier.

They use our batteries!

Our batteries are already powering Pony bikes in French cities!
