  • 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.
  • 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
  • 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
  • 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, Maximum Amperage before Breaker Trips: 20A.

  • 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.
  • ----------------------------- Trouble Shooting -----------------------------
  • Trouble: Set this up to test a 3s li-on pack on a 10 watt LED the display lit for a couple minute then the module went dead never worked.
  • Reason: The module is only suitable for a single battery, not for battery pack.
  • Solution: Please connect with a single battery.
