One of the best vector controllers for brushless electric motors on the market. It is possible to use a PC or from a phone on IOS and Android via Bluetooth to change many settings in a very wide range, namely: Set phase and battery current separately in any proportions. Limit the minimum and maximum voltage of the battery (up to 90V) in order to protect it. Adjust the operating voltage of the accelerator handle, which allows you to obtain protection against independent starting from a standstill in case of damage (short circuit of the contacts of the Hall sensor) of the accelerator handle. Adjust the temperature at which the power will be limited, and then the controller and the engine will be turned off (a temperature sensor must be installed in the engine).
