After Redding Mango charged the car, the problem was that the starter battery was running out of power, so we needed help from other car owners to deal with the problem. Leaving Redding Mango for a few days without turning it on or forgetting to turn off the headlights will result in the battery being full. However, if the battery is depleted to start, you need to find the location of the batteries of the two cars and the positive and negative terminals of the batteries. First use the red one to connect the positive terminals of the two cars. , use the black wire to connect the negative poles of the two cars to start the fire.
