This is a safer and power saving battery automatic charging power control board. Tiny module, but with larger current, high accuracy, well protection function. The default Starting Voltage is 10.5V-11.5V, Shutdown Voltage is 14.4V-14.8V.

Features:

Safe and Power Saving: 12V charger power control board which features with automatic power on/off charging function

It'll be charged automatically when the voltage is lower to 10.5V-11.5V, while it'll stop charging when the voltage is 14.4V-14.8V

Indicator LED light is provided: The light will be red when it's charging, while is off when the charging is over

The max. of transformer is 2KW,. the battery can detect the high and low level through the protection board to manage the charging

With reverse protection function that there is no output when it has not been connected to the battery

Description:

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

When first starts charging test, please discharge the storage battery. If you connect the battery, and the red lamp is off immediately and the relay disconnects, please contact us and do not adjust the potentiometer in person, or it won't restore to normal status.

Function 1: this board can allow 2KW transformer, and the battery can detect high level or low level so as to achieve auto charging management.

Function 2: 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, this is an very practical function. Output short circuit and auto closed are also practical protection. No matter the charger is in what kind of status, once output is short circuit, then the charger will automatically close the output.
