Three-pack low-voltage protector

The KEHIPI XH-M609 modules protect 12-36V lithium or lead-acid batteries from over-discharge. Each board disconnects the load automatically when voltage falls to a user-set threshold. Control accuracy is 0.1V and the onboard relay handles momentary peaks up to 20A. Three identical units are supplied for multi-battery installations.

Single-battery systems only

These protectors suit standalone batteries in solar, UPS or portable equipment where automatic cut-off preserves cell life. They are not for series or parallel battery packs, nor for voltages outside the 12-36V DC range. Builders needing pack-level management or higher current ratings should look at different hardware.

Sustained operation behaviour

Under continuous load the module draws 1.5W and passes the supply voltage unchanged to the output. When the programmed low-voltage limit is reached the relay opens and the load is removed; the board itself remains powered until the supply is manually disconnected. The three-digit red LED shows real-time voltage and the configured hysteresis value during normal running.

Questions about this item

What battery voltage range must the XH-M609 module connect to for it to operate?

The module works with a single 12-36V lithium or lead-acid battery; supply voltage equals output voltage.

If I keep a 12V lead-acid battery, will the module protect it from over-discharge?

Yes, it disconnects the load automatically when voltage reaches the set threshold and reconnects after the hysteresis value is met.

How can I confirm the protection settings are active after wiring the board?

Press the "+" button to view the low-voltage cut-off value and "-" to view the hysteresis; the 3-digit red LED shows both parameters.
