Happy BMS is especially designed to be hardware and software compatible with Xiaomi and Ninebot electronics, so you can use it to easily make custom batteries. A battery equipped with Happy BMS is recognized by Xiaomi and Ninebot electric scooters as original, keeping all the functionality of the scooter. 


    The main Happy BMS feature is up to 15s battery support, which means you can equip your scooter with a 15s battery instead of the original 10s, reaching +50% to the maximum speed. You can also configure some parameters, such as capacity, discharge curve, serial number and maximum current, improving the performance of the scooter.
