Features:
Start charging voltage and stop charging voltage can be freely set, automatically cut off power to save power and extend service life of battery.
The board has a bright 3 digit display with 0.1 accuracy shows the setting value.
Start or stop according to the set value, and monitor real time voltage, to effectively protect storage battery from overcharge.

Charging voltage generally is not higher than 1.2 times that of battery voltage. For example, if battery voltage is 6 V, charging voltage is between 6V and 7.2 V.Charging current is better to be no more than 1 10 of the battery capacity. preferred.Max. Charging Voltage= Battery Voltage x 1.2;Max. Charging Current = Battery Current x 0.1
Note:
1, The default start voltage is 12V, and default stop voltage is 14V. When setting voltage, if one voltage value is not able to set, you can set the other voltage value first, then set this voltage value.
2, Set start charging voltage according to tested battery voltage when it need being charged(tested by yourself with a voltmeter), and set stop charging voltage according to tested battery voltage when it is fully charged(tested by yourself with a voltmeter).
Package Includes:
1 x Protection Board
