In this video I show how to open up the battery casing for the Dyson hand held vacuum systems, and how to evaluate the viability of the battery cells and the BMS Battery Management System circuit board that controls the battery functions. This battery supports most hand held models V4, V6, and V7. How to use a multi-meter to check the battery voltages.
Spare parts for these units are available on Amazon:
* Replacement Pre-Filter and Post-Filter: amzn.to/3qPk5Le
* Replacement Batteries: amzn.to/2W4CEwL
Gear used for Filming:
* GoPro Hero Black - amzn.to/3ls3KJY
* GoPro Mounting Kit - amzn.to/2IgQjNJ
For the record, once the Dyson BMS detects a fault, they can never be fixed, even if the cells are changed. I replaced some aging but balanced Sony cells with some IMR cells that had issues. It worked fine but would cut off due to voltage sag if I put it on turbo mode. I got some replacement Sanyo HG2 cells but one was bad so I had one mismatching cell in there. This caused a red light. Even after replacing all the cells with good batteries, the flashing red light will not go away. If there was a way to reset it it would be great but Dyson doesn't want that. They claim that it is for safety but I believe that isn't the only reason.
Sam problem red light

🤞Right-To-Repair whoops their asses, but not betting on it.
A bench-type variable DC power supply might save the day by experimenting different options like - to re-charge the individual battery , to check if each of them still good and to apply 24v. DC to BMS that detects the condition of the cells and see if the red light will stop. This is not easy to troubleshoot.
Can you charge individual batteries without taking out of the assembly by hooking that lower voltage battery up with a separate charger?
yes you can.
wow, all i do is clamp the short section in a vise, on the sides of the battery and pull the halves apart, haven't damaged one yet. also, after as many as 30 disassembled I have only found one bad cell, and it appeared to have got wet. its more like planned obsolescents, in other words Dyson programs them to fail, especially if you use the turbo settings. a fully charged battery can only handle the high speed load for a short period of time, no way will it work full time defiantly not worth the money.
What do we do if the red light flashes ten times only?
You don’t need to change the board and batteries just reset and rewrite the faulty code in computer. Japanese electronics technicians is doing it just like that…
But they are japanese. Americans don't give themselves a headache to solve this kind of situations because replacement battery was cheap for them. They basically throw the old one away and replace with a new one
Can you provide me some japanese resources that i can use to diagnose my own v8 battery i cant find proper resources on the internet
