The V22 JK BMS is roughly 40% smaller than the V19 and uses entirely new components. While V22 reduces the maximum active balancing current from 2A to 0.6A, the V22 model is equipped with an additional WIFI module interface; the WIFI module can be directly connected to the UART interface of the BMS.
