Reset:
When the power is off, press and hold both buttons at the same time, and then power on. At this time, "888" is displayed on the screen to indicate that the factory reset is successful.
Factory set protection value: 12V, return difference: 2V
Scope of application:
Suitable for all electric two-wheel tricycle batteries in the applicable voltage range;
Car battery and new energy electric vehicle battery discharge protection;
Over-discharge protection of various batteries;
Solar, wind and other power supply systems.
Instructions:
When the new battery is used for the first time, the rated voltage value is close to the actual value, and the stop discharge voltage can be judged. A reasonable discharge voltage value can be obtained according to the normal voltage calculation method of the battery.
When the old battery is used, the actual voltage value and the rated voltage value are quite different. You need to measure the termination voltage value in actual use yourself.
Slow charging is usually used for battery charging (in the case of fast charging, the voltage and current are relatively large, 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 rated capacity current of the battery. For example, the charging voltage of a 6V50Ah 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
Package includes:
1 x Battery over-discharge protection module
