Product wiring
Set the usage settings to stop below 12.5V and start above 14V:
Set the protection value: press “+” once to display the protection value. Double click “+”, and the Decimal separator flashes. At this time, press “+, -” to change the value to 12.5. If there is no operation for 3 seconds, the module will automatically save and exit the setting mode.
Set the return difference value: press “-” once to display the return difference value. Double click “-“, and the Decimal separator flashes. At this time, press “+, -” to change the value to 1.5. If there is no operation for 3 seconds, the module will automatically save and exit the setting mode.
Set to stop below 10V and start above 15.5V:
Set the protection value: press “+” once to display the protection value. Double click “+”, and the Decimal separator flashes. At this time, press “+, -” to change the value to 12.5. If there is no operation for 3 seconds, the module will automatically save and exit the setting mode.
Set the return difference value: press “-” once to display the return difference value. Double click “-“, and the Decimal separator flashes. At this time, press “+, -” to change the value to 1.5. If there is no operation for 3 seconds, the module will automatically save and exit the setting mode.
Factory reset
When the power supply is disconnected, press and hold two keys at the same time, and then power on. At this time, the screen displays “888”, indicating that Factory reset have been restored successfully.
Factory set protection value: 12V, return difference: 2V
Applicable scope
Suitable for electric two wheel tricycle batteries within all applicable voltage ranges;
Discharge protection of automobile battery and new energy Electric vehicle battery battery;
Overdischarge protection for various batteries;
Solar, wind, and other power supply systems.
Usage method
When a new battery is first used, the rated voltage value is close to the actual value, and the stopping discharge voltage can be determined based on the general voltage calculation method of the battery to obtain a reasonable discharge voltage value.
When using an old battery, there is a significant difference between the actual voltage value and the rated voltage value, and you need to measure the termination voltage value yourself in actual use.
Generally, the battery is charged slowly (the voltage and current can be relatively large in the case of fast charging, but the battery is easily damaged.) The slow charging voltage is 1.2 times the rated voltage, and the charging current is adjusted to about 2/10 of the current of the battery’s Nameplate capacity. For example, the charging voltage of a 6V 50Ah battery is about 7.2 volts, and the charging current is adjusted to 10A.
Reference formula: Charging voltage=rated voltage X1.2 Charging current=rated current X0.2
