First, a depleted battery or a poor battery connection may cause the ESC to not receive sufficient power supply.

Secondly, circuit failures inside the ESC, such as damaged capacitors and failed relays, may also cause the ESC to fail to function properly.

A sudden increase in noise usually means that there is a problem inside the motor. On the one hand, badly worn or improperly installed brushes can cause an abnormal sound when rubbing against the commutator. On the other hand, damaged bearings or insufficient lubrication can also cause mechanical noise.

Wear and tear of the swing arm after long time use does affect the performance of the vehicle. A worn swing arm may cause inaccurate wheel alignment, which in turn may affect the vehicle’s handling and driving stability. In addition, wear may increase friction between the swing arm and other components, resulting in rattles and additional energy loss.

This situation may be caused by abnormalities in the vehicle’s power system, triggering of the charger’s internal protection mechanism, or malfunctioning of the charging interface. First, check whether the vehicle power system is normal, for example, whether the battery is drained or damaged. Secondly, check if the charger is triggered by…[Read more]

First, batteries age with increased use and their ability to store electrical energy decreases.
Second, incorrect charging habits, such as overcharging or discharging, can also accelerate the aging process of a battery.
In addition, if the battery has not been used for a long period of time, self-discharge may also occur, resulting in a decrease…[Read more]
