Description
The XH-M609 DC 12V-36V Battery Over-Discharge Protection Board is a specialized low-voltage protection module designed for 12V to 36V lithium-ion and lead-acid batteries. Engineered to safeguard your power storage systems, this board actively monitors real-time battery voltage and automatically disconnects the load when voltage drops below your preset threshold, preventing harmful deep over-discharge and significantly prolonging battery lifespan.
Featuring an onboard momentary push-button and a clear digital display, setting up and adjusting your low-voltage disconnect parameters is quick and straightforward. It also includes an automatic autosave function to retain your settings and automatically reconnects the circuit once power or charging is restored.
Note: Product images are for reference only; actual appearance or labeling may vary slightly based on manufacturing batches. Battery packs are not included.
