Battery Charge Protection Board Auto Start Stop Module

Feature:
The protection board supports power supply TVS surge protection; when power on, power supply has a instantaneous high voltage, and TVS can reduce instantaneous high voltage to protect circuit.
The 1% high precision divider resistor makes voltage measurement more accurately.
Voltage precision and resolution is 0.1 V, and has calibration function.
Lower digital tube display brightness, energy saving and protect your eyes.
Save parameters when power failure to avoid repeated settings.
If set start and stop voltage to a minimum (< 6V), it can be used as a voltmeter to measure 7 to 60V voltage.
With energy saving mode and restore to factory setting function.
Designed with three control buttons, four-digit display, 1 charging indicator LED light.
It can charge 6-48V lead-acid battery and lithium battery; charger voltage range is DC 7 to 60V.
