If the capacity of the battery is too small, it cannot meet the needs of lighting at night. If the battery is too large, the battery will always be in a state of power deficit, which will affect the life of the battery and cause waste.

When the voltage detected by the voltage sensor is low At 13V, start the intermittent pulse charging method.
