Digital LED Display Low Voltage Disconnect Switch Cut Off 12V 24V 36V 48V Over-Discharge Protection Module for DC 12-36V Lead Acid Lithium Battery

Description:

- Programmable battery low voltage disconnect switch for DC 12-36V lead acid battery and lithium ion battery. It's a protection switch module, not included batteries itself.

- 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 avoid the battery from over discharging to prolong the battery lifetime

- 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.

Operation Instructions:

- Press "+" the LED displays the low voltage protection parameter. Hold on the "+" to enter setting manual to set the protection parameter

- Press "-" will display the difference value. Hold on the "-" to enter setting manual to set the difference value.

What is the "difference value"?

The value between the battery voltage to disconnect and the battery voltage to reconnect.

For example

I want the battery to stop outputting when the battery voltage is lower than 11V and re-output when it is over 11.6V. What should I do?

Hold on "+" and set the value as 11. The LED starts flashing. After the flashing stops, hold on "-" and set the difference value as 0.6V.

Q & A:

Q: How long will this module charge the car battery?

A: The module does not charge itself, it only turns on and off the charge.
