Battery Protection Module
The anicorn XH-M609 is a low-voltage disconnect module designed for single 12-36V lithium or lead-acid batteries. It monitors supply voltage and automatically cuts the load when the user-defined threshold is reached, preventing deep discharge and extending battery life. The unit ships in a pack of three and requires no battery to operate. It suits off-grid solar, portable power or automotive auxiliary circuits where unattended protection is needed.
Thermal and Power Behaviour
The module draws less than 1.5W during operation and can pass an instantaneous 20A before its internal breaker trips. Control precision is 0.1V, so the disconnect point is repeatable across the 12-36V range. No active cooling is fitted; the board relies on free-air convection, so mounting in a ventilated enclosure is advisable when running near the current limit for extended periods.
Build and Connections
A momentary push button and three-digit red LED let you set the cut-off voltage without external tools. Output voltage equals the supply voltage, and the terminals accept 6-60V wiring. The relay lacks a hard power-off switch, so the supply must be disconnected manually after a trip to stop the module from draining the battery to zero. Each board is compact enough for DIN-rail or panel mounting in tight cabinets.

Questions about this item
How do I wire the XH-M609 module to my 12V battery and load?
Connect the battery to the input terminals and the load to the output terminals. Set the cut-off voltage using the on-board push button while watching the 3-digit red LED display. Remember to manually cut power after the relay trips, because the module has no built-in power cut-off switch and will drain the battery to zero.
What maintenance will the XH-M609 need over time?
The module itself has no user-serviceable parts or consumables. Periodically verify that the low-voltage disconnect threshold remains accurate by comparing the LED reading with a multimeter. Check terminal screws for tightness and ensure the enclosure stays free of dust or moisture that could affect the relay contacts.
What is the first limit reached when the load runs continuously at high current?
The instantaneous maximum current before the circuit breaker trips is 20A. Sustained loads approaching this level will trigger the over-current protection first, disconnecting the load to protect the battery and module. The unit draws less than 1.5W itself, so internal heating is minimal compared to the relay's current rating.
