2X(Powerful start, climbing power large and small motor noise.
When the battery voltage become lower, the current will also become lower to keep normal running.
It only protect the battery and extend the battery life, but also increase the running distance.
Production technical of Controller and authentic quality.
When the motor phase is failure, controller will protect it, avoid motor burned, and protect the battery at the same time.
