Most battery problems may be solved in less than an hour, no requiring special skills and tools.

This video is still relevant in 2024: we produce BMSes and sell it. Don't be confused that there are no new videos at the channel: the thing is I am superbusy with manufacturing and really have no time to make movies. But I release all new stuff in my blog at escooters.embedden.com :

Xiaomi M365 is an excellent electric scooter, but it has a weakness: the battery, which can fail for a number of reasons. This video demonstrates an universal solution, that allows to fix all factory defects, as well as adding new useful features to the scooter. We will throw out from the battery unreliable factory electronics, installing a compatible smart BMS instead.

Feel free to ask your questions!

Please note that good condition of battery cells is necessary for successful repair. This can be checked by measuring the voltage. If cell’s voltage is in the range from 2.5 to 4.2 volts, it is OK, otherwise it must be replaced.

A battery equipped with a new BMS can be flexibly configured. It is possible to set capacitance, output current, discharge curve, and much more. Check the user manual for the full list of available settings.

Here is a link to the user manual: http://public.embedden.com/Repair_BMS...

The battery is configured via the smartphone application:
Android app https://play.google.com/store/apps/de...
iPhone app is under construction.
