Battery Charging Control Board, 12V Intelligent Power Control Board Charger Power Supply Controller Board Battery Controller Automatic Switch Module

welcome to my shop: Introduction:  1.Starting Voltage: 10.5V-11.5V 2.Blocking Voltage: 14.4V-14.8V 3.Size: 50*32*18mm 4.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 5.When first starts charging test, please discharge the storage battery.  Function: This board has reverse connection protection; when it does not connect battery, there is no output; whether the battery clips in the output port touch or not, users can plug it safely. When the polarity of the battery connects reversely, there is no output. Output short circuit and auto closed are also practical protection.  Adjust 1: V
