Welcome to the Unofficial Dyson V10 Battery Management System firmware page!

The purpose of this project is to produce replacement firmware for the V10 Battery Management System for Dyson vacuum cleaner battery packs.

It's needed because the original, 'stock' firmware will permanently disable the pack if certain cell faults occur (such as out-of-balance >300mV). Even replacing the cells will not allow the pack to work again, confining it permanently to eWaste. This is not cool.

This firmware allows you to unlock the pack again, rebalance it, replace the cells, use it for a different purpose, even! Whatever you want.

Take control of your packs!

(Even better, you can do it with a Raspberry Pi as the programmer, so you don't even need to buy expensive hardware to do it - more info on this to follow!)
