When charging an electric scooter, bike, or go cart battery pack the vehicles power switch or key switch should be in the off position.

The battery pack will still charge if the switch is in the on position however it will take slightly longer to charge than if the switch was in the off position.

The most important reason to recharge the battery pack with the vehicles power switch off is to prevent the vehicle from being operated while it is being charged by accidentally pressing or twisting its throttle. Another less important reason to recharge with the power off is to lower the amount of hours that the vehicle's power is on to prolong the life of its electrical components.
