## Features

- 🌟Board Size: 57 X 42 X 19mm/2.24 X 1.65 X 0.75inch(L*W*H), Input Voltage Range: DC12-36V, Control Accuracy: 0.1V, Power Consumption: <1.5W, Instantaneous maximum current before circuit breaker trip: 20A.
- 🌟Note:Due to the limitation of the size of the PCB board, the relay size of this module is mini and the circuit lines are very thin. The current should not be too large during actual use. If the current exceeds 8A, the relay contacts may be blown and cannot be used normally.The maximum current is 10A when the voltage is below 12V, and less than 8A when the voltage exceeds 12V
- 🌟Programmable battery low voltage disconnect switch for DC12-36V lead acid battery and lithium ion battery. It's a protection switch module, not included batteries itself.Compatible Battery: lead acid, lithium ion battery, solar panel battery.Not suitable for battery packs.
- 🌟On-board momentary push button to set the low voltage disconnect parameter and 3 digit red LED display the parameter easy to operation.When the battery voltage reach the setting values, the module will disconnect load automatically to aviod the battery from over discharging to prolong the battery lifetime. (Note:The relay does not contain a power cut-off switch,remember to cut off the power supply after disconnection, otherwise the module will continue to use the battery until the voltage is 0.)
- 🌟Reset:When the power is off, press and hold the two buttons at the same time, and then power on. At this time, the screen displays "888", indicating that the factory settings are restored.The factory-set protection value: 12V, difference value: 2V.Difference Value"is the value between the battery voltage to disconnect and the battery voltage to reconnect.
- 🌟Display is accurate, the switch module is quickly to open and close when near minimum voltage; Settings is stored non-volatile, it can keep set when power off

## Questions & Answers

**Q: I have 20v input and want 6v output can you set the output voltage? I need low voltage protection and the ability to step down the voltage.**
A: What you need is called a "buck". There are 3 kinds: step-up, step-down and step-up/down.

I use a step up/down buck with this low-voltage cutoff module. As the output voltage from the LiPo battery that I'm using drops from 12.4V at fall charge to 10.4V at minimum operating voltage, the buck maintains a constant 12.0V to the powered device. When the battery reaches it's minimum recommended operating voltage of 10.4V, the low-voltage cutoff module cuts off power to prevent the battery from further discharging. LiPo batteries can be permanently damaged if they fall below about 9V output (and they're expensive to replace!)

**Q: Will this work with LiPo batteries?**
A: yes

**Q: I can connect this to a li ion battery and it will output enough power for a 300w inverter? Something like 25 amps?**
A: In your scenario, you would use this module to control a higher amperage relay that can handle the higher load. Just connect the output of the protection module to the control terminals of the larger relay.

**Q: Why is imput voltage 12-36 but output is 6-60V?  Can this be used with 56V battery?**
A: Grammatical error, 36v max, in you're case it it will work if you have access to the connections of the individual cells or banks
