How to Use Battery Charging Power Control Board?
When the battery voltage falls to the range of 10.5-11.5V (low voltage adjustable), then the protection board will automatically charge again; when the power off voltage is in the range of 14.4-14.8V, the protection board will stop charging (high voltage adjustable). During the charging process, the red lamp is on; when it is fully charged, red lamp is off. When the relay disconnects, 220V input port will end charging so as to save the energy.
