Battery over-discharge protection module XH-M609

Product Name：Battery over-discharge protection module
Product Model:XH-M609
Supply voltage：12-36V
Output voltage: equal to supply voltage
Control precision: 0.1V
Power Consumption: Scope of application: all kinds of batteries Lithium batteries
Product size: 57*42*19mm

Instructions for use:
+ key: press once to display the protection value, long press to set the protection value - key: press once to display the return value, produce ammonia to set the return value

Setting example
Stop voltage is lower than 11V and start voltage is higher than 11.6V.
Method: Long press + screen flashing set to 11, and then long press - screen flashing set to 0.6, then OK

Disconnect when voltage is lower than 12.5V and start when voltage is higher than 14.8V.
Method: Long press + screen blinking to set the stop value to 12.5, wait for the screen does not flash, and then long press - screen blinking to set the voltage difference back to 2.3V.

The board has even solder application, the screw terminals are free to turn and correctly assembled. No issues in connections or operation. Great board for battery management.

This product is a great addition to either batteries without BMS protection or some DIY project require specific range of voltage input without over discharging the input battery. It works as expected.It doesn't work beyond my expectation, it doesn't come with any physical documentation, specification or manual whatsoever, so it can't be a 5-star product. The best would be a 4-star instead.The plus "+" button is actually the left one instead of the right one, the right one is the minus "-". The design is contradicting our traditional numeric line.It allows you to set the low-voltage cutoff, which will disconnect the relay upon reaching lower than this value.Then, the other value to set is the "delta voltage", which on top of the low-voltage cutoff, will make the relay ON. The relay will keep on when the input voltage is in the range of low-voltage cutoff+delta, until the input battery is depleting and goes lower than the low-voltage cutoff.It is that simple, great for protecting LiFePo4 or especially Lead-Acid battery which doesn't has BMS.However, the relay on/off voltage is a little bit not very accurate, there is +/- 0.1V error, so, be sure to test the on/off behavior with multi-meter to be sure.I also don't like the relay is "hardwire" to the battery +/-, thus the relay can't be used for connecting/disconnecting something else. The relay is switching on/off ONLY between the input positive and the output positive.Good for an additional protection to the battery from discharging too low to damage itself.
