The main differences between the CE version and the international version are the motor power, maximum speed, throttle mode and torque, where the CE version has a motor power of 250W, a maximum speed of 25km/h, does not support throttle mode, and has a torque of 37N.m; while the international version has a motor power of 500W, a maximum speed of 32km/h, support for throttle mode, and has a torque of 50N.m. The international version has a motor power of 500W, a maximum speed of 32km/h, and supports throttle mode.

The function of the battery converter is to read the highest voltage in the battery bank (e.g. 95% for bank A and 50% for bank B). The converter will prioritise the use of the higher-charged Group A batteries (the meter display is also from Group A). When the battery level of group A drops to the same level as group B (50%), the converter will go into operation, discharging both batteries at the same time. Also, if you use the A bank batteries alone and drain them to 10%, and let the B bank step in to work without switching off the power, the meter will still show a 10% charge. However, if you switch off and restart, the converter will re-read the battery with the higher charge.
