Onyehn 2pcs DC 12V-36V Voltage Protection Module Digital Low Voltage Protector Disconnect Switch Over Discharge Protection Module Output 6-60V

Onyehn 2pcs DC 12V-36V Voltage Protection Module Digital Low Voltage Protector Disconnect Switch Over Discharge Protection Module Output 6-60V

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.

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: I can connect this to a li ion battery and it will output enough power for a 300w inverter? Something like 25 amps?

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?

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
