Happy BMS for Xiaomi

Happy BMS is hardware and software compatible with Xiaomi e-scooters, so you can make a custom extended battery, which is recognized by the scooter as original, keeping all the functionality.

The main Happy BMS feature is up to 15s battery configuration support, which means you can equip your scooter with a 48V or even 54V battery instead of the original 36V one, reaching +50% to the top speed. You can also configure some parameters, such as capacity, discharge curve, serial number and maximum current, improving your scooter performance.

Classic general purpose BMS require a lot of extra work to solder wires and plugs, while Happy BMS is already equipped with all the necessary wires, plugs and sensors, so you only need to solder a few power and balancing wires.

Happy BMS is the result of my many years of experience in making batteries for Xiaomi and Ninebot electric scooters. It can be said that this is a product from a battery manufacturer for battery manufacturers.

UPS Express, 5 - 10 business days. We ship from Krakow, Poland. No taxes for EU customers.
