2 Pack DC Voltage Protection Module For 12 36V Batteries With Digital Low Voltage Cutoff No Nonsense Over Discharge Protection Disconnect Switch And Easy Safe Shutdown For Lead Acid And Lithium Battery Systems

Two-Pack DC Voltage Protection Module for 12-36V Batteries
✔️ Input 12-36V DC, adjustable cutoff ~12V, 8A max relay

This voltage controller uses a relay to switch the output on and off without changing the voltage. It's a protective switching module for 12-36V battery systems and works with lead-acid, lithium-ion, and solar panel batteries. This 2-pack unit does not include batteries and is designed to prevent deep discharge by automatically disconnecting the load at the preset voltage.
