NOTICE:

1.Programmable battery low voltage disconnect switch for DC12-36V lead acid battery and lithium ion battery. It's a protection switch module, not included batteries itself.Compatible Battery: lead acid, lithium ion battery, solar panel battery.Not suitable for battery packs.

2.The relay does not contain a power cut-off switch,remember to cut off the power supply after disconnection, otherwise the module will continue to use the battery until the voltage is 0.

3.Due to the limitation of the size of the PCB board, the relay size of this module is mini and the circuit lines are very thin. The current should not be too large during actual use. If the current exceeds 8A, the relay contacts may be blown and cannot be used normally.

Package Included:

2x Protection Module.

How to use: The first time a new battery is used, the rated voltage value is close to the actual value, Judgment to stop the discharge voltage. A reasonable discharge voltage value can be obtained according to the general voltage calculation method of the battery. When the old battery is used, the actual voltage value and the rated voltage value are quite different, so you need to measure the stop voltage value in actual use.
Battery charging usually uses slow charging (the voltage and current of fast charging are relatively large, and the battery is easily damaged.) The charging voltage of slow charging 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 6V 50Ah battery is about 7.2V, adjust the charging current to 10A.
