Common Battery Charging Voltage for reference only:

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.. Charging Voltage= Battery Voltage x 1.2;. 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
