Repair BMS is designed to be installed inside a Xiaomi Mijia M365 / M365PRO electric scooter battery instead of an original BMS. This is required when an original BMS fails, or when tuning the battery by replacing all cells with more capacious ones. It is also possible to use this BMS for any self-assembled 10s battery.
A battery equipped with a repair BMS is recognized by the Xiaomi Mijia M365 / M365PRO electric scooters as standard, so all the original functionality is preserved. In addition, it becomes possible to flexibly configure many parameters, for example, capacity, discharge curve, serial number, maximum current, and many other parameters.
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.
