How I Rebuilt a Dyson V10 Battery Pack

In this video, I'm going to show you how to rebuild a Dyson V10 battery pack. I've rebuilt many battery packs, mostly yellow ones, and usually, the problem lies with the cells. However, with this Dyson V10, all the cells tested good, which led me to the Battery Management System (BMS) as the culprit. I'll walk you through the process of disassembling the battery, identifying the issue, and replacing the faulty BMS. I'll also share some tips and tricks, like using guitar picks to safely open the battery pack without damaging it. This project can save you a significant amount of money compared to buying a new battery. While rebuilding battery packs might seem daunting, it's pretty straightforward if you take it one step at a time. Always double-check your connections and polarity to ensure a successful repair.
