1. Scope of application
Applicable to all electric two-wheeled and three-wheeled vehicle batteries within the applicable voltage range; discharge protection of automotive batteries and new energy electric vehicle batteries; over-discharge protection of various batteries; solar energy, wind energy and other power supply systems.
2. Setting and use:
Set to stop below 12.5V and start above 14V:
Set protection value: Press "+" once to display the protection value, double-click "+", the decimal point flashes, and press "+, -" to modify the value to 12.5. If there is no operation within 3 seconds, the module will automatically save and exit the setting mode.
Set the hysteresis value: Press "-" once to display the hysteresis value, double-click "-", the decimal point flashes, and press the "+, -" key to change the value to 1.5. If there is no operation within 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 "+", the decimal point flashes, and press the "+, -" key to change the value to 12.5. If there is no operation within 3 seconds, the module will automatically save and exit the setting mode.
Set the hysteresis value: Press "-" once to display the hysteresis value, double-click "-", the decimal point flashes, and press the "+, -" key to change the value to 1.5. If there is no operation within 3 seconds, the module will automatically save and exit the setting mode.
3. Restore factory settings
In the power-off state, press and hold the two buttons at the same time, and then power on. At this time, the screen displays "888", indicating that the factory settings have been restored successfully.
Factory setting protection value: 12V, hysteresis value: 2V
4. Usage:
When a new battery is used for the first time, the rated voltage value is close to the actual value. To determine the stop discharge voltage, you can get a reasonable discharge voltage value based on the general voltage calculation method of the battery.
When the old battery is used, the actual voltage value is quite different from the rated voltage value, and the termination voltage value needs to be measured in actual use.
Battery charging usually uses slow charging (fast charging can have relatively large voltage and current, but it is easy to damage the battery). The slow charging voltage is 1.2 times the rated voltage, and the charging current is adjusted to about 2/10of the rated capacity current of the battery. For example: The charging voltage of a 6V 50Ah battery is about 7.2 volts, and the charging current is adjusted to 10A.
5. Reference formula: Charging voltage = rated voltage X1.2 Charging current = rated current X0.2
