The repairable battery

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

We love e-bikes! But as they become increasingly popular, we start to see more and more people frustrated with their batteries.

Existing batteries are too impractical and dangerous to repair, and often end-up being discarded for only minor defects.

This results in a lot of ecological and economical waste.

Gouach set out to build the first sustainable and fully repairable electric battery.

Our team invented an easy-to-use battery that is as reliable and powerful as market leaders, but is also eco-friendly.

The Gouach battery is packed with features, fully customizable, and comes with an easy-to-use API, documentation, and friendly community.

Protecting our environment just got easier!


Environmentally-friendly battery

A patented solder-less design which allows to repair the electronics and change the cells in less than 10 minutes.

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. You can get a fresh battery, and give a second-life to old cells.
Reduced CO2 footprint
The Gouach repairable design allows up to 70% 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 designed for your needs.

Get full BLE and WiFi connectivity without a new component. Our battery is even capable of passive SSID geolocation.
Sequential discharge
Sequential discharge lets you link multiple batteries together to get even more power, while making it easy to swap batteries.
Lithium protection
Activate this option and trade 10% of your range for 200% of battery life. This increases the durability of the battery even more!

Fully customizable.

We offer custom form-factors to fit in any product.

Form factor
We can adapt our battery to retro-fit the connectors you are using, or design a brand new battery according to your specs, in less than a week.
Power needs
We can design your battery to address any power need, from handheld tools to e-bikes, e-mopeds, or golf carts.

They use our batteries!

Our batteries are already powering Pony bikes!
