Introduction
Introduction
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 pack.
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.

Activity and error
indicator
Flashes every half second in normal operation.
In case of an error, displays its code.
For more information on error codes, see the “Troubleshooting” section.
Temperature sensors
Information from these sensors is displayed in the smartphone application. If the
sensors detect an excess of the permissible temperature, the BMS temporarily
disables charging and discharging the battery.
Thermal fuse
Irreversibly melts at a critical temperature rise of the battery, completely turning
off the BMS power and, accordingly, the charge and discharge of the battery.
Current fuses
Irreversibly burn out at a critical overcurrent if the software protection did not
work.

WARNING!
Follow the wiring sequence, otherwise the BMS may irreparably fail, with a loss of
warranty.
1. Connect the black power wire of the BMS to the negative lead of the battery pack.
2. Connect the red power wire of the BMS to the positive lead of the battery pack.
3. Connect the balancing wires in order, starting with B0 and finishing with B10.
4. Install temperature sensors and thermal fuse using a thermal compound or neutral sealant with thermal
grease.
5. Solder the connector that comes with the BMS to the rear light wire.
6. Connect the battery to the scooter.
7. To start the BMS for the first time, connect the charger to the scooter. In case of a successful start, the
indicator LED will blink on the board.

WARNING!
The cable does not come out of the board in the most convenient way, and when
connecting the balancing wires, you have to cross them. The thing is that initially BMS was
designed even before the PRO version of the scooter appeared on sale, after which the form
of the board was only slightly changed to maintain compatibility.
WARNING!
Follow the wiring sequence, otherwise the BMS may irreparably fail, with a loss of
warranty.
1. Connect the black power wire of the BMS and B0 balancing wire.
2. Connect the balancing wires in order, starting with B1 and finishing with B9.
3. Connect the red power wire of the BMS and B10 balancing wire.
4. Install temperature sensors and thermal fuse using a thermal compound or neutral sealant with thermal
grease.
5. Solder the connector that comes with the BMS to the rear light wire.
6. Connect the battery to the scooter.
7. To start the BMS for the first time, connect the charger to the scooter. In case of a successful start, the
indicator LED will blink on the board.

Setting up the battery
Setting up the battery
The repair BMS provides the ability to flexibly configure many parameters. The default values can be
left unchanged when the BMS is used just to replace the faulty original Xiaomi M365 board. In the case of the
PRO version of the scooter, you must additionally configure the battery capacity. And if you change cells to
new ones or even assemble your own battery pack, you need to configure a number of parameters to operate
with the new cells.
Please, use the “M365 BMS Tool” application to configure your battery:
