FU-Dyson-BMS - (Unofficial) Firmware Upgrade for Dyson V6/V7 Vacuum Battery Management System

In this video I demonstrate and walk through the installation process of the replacement firmware I developed for the V6 and V7 Dyson Cordless Vacuum batteries. This firmware eliminates the "feature" in the factory Dyson firmware where the battery will permanently stop working if the cells ever go too far out of balance. It also provides several new LED codes so you can monitor the health of your battery pack.

Revolutionary features:
Cell balance LED indicator
State of charge LED indicator
Robust fault handling and logging
Total runtime tracking
Can be run in debug mode for near-real-time diagnostics
Doesn't brick itself!
Doesn't generate e-waste and try to take your money when your cells go out of balance!
