Q:1. What current BMS should I choose?

A: Take 10S36V as an example: what current BMS you choose relies on your E-bicycle Motor power and the current limitation of the controller. eg., choose 16A for below 350W, 25A for below 500W, 35A for below 800W, 60A for Below 1000W, higher than 1200W are contact with our service specialist for suggestions, one in all, continue current shall be higher than a current limitation in Controller.

Q:2. Whether my BMS damaged?

A: if you want to judge if the BMS is damaged, please take the following steps, to test if each cell voltage is the same as with the voltmeter. if the cell voltage difference is over 1.0V, the fault is displayed that it cannot run far, no power supply at the start range, short charge time, all these issues are almost caused by battery cells, if BMS damaged is displayed as no charge, no discharge, no discharge while the battery has voltage.
