## Description

Icstation digital battery overdischarge protection switch is specially designed for 12-36V lithium and lead acid battery. This is a low voltage protection module, not included batteries itself. On-board momentary push button to set the low voltage disconnect parameter, 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. Specifications: Input Voltage Range: DC12-36V Control Accuracy: 0.1V Compatible Battery: lead acid, lithium ion battery, solar panel batteryBoard Size: 57 X 42 X 19mm/2.24 X 1.65 X 0.75inch(L*W*H)Package Included:1X Lead Acid Lipo Battery Charge ControllerOperation Instructions:+: short press display the low voltage protection parameter, long press to change the protection parameter -: short press to display the difference value, long prss to change this parameter. e.g. battery voltage lower than 11V will stop ouput and higher than 11.6V start output.long press "+" and set it as 11, then long press "-" and set it as 0.6V.

Review: does the job — it's handy!
Review: It just works! Very simple, and very capable.

## Features

- NOTE: This product is a voltage controller, which turns on and off the output through a relay, which only acts as a switch and cannot change the voltage. It's a protection switch module, not included batteries itself.
- OVER DISCHARGE PROTECTION: This battery controller provides a high degree of flexibility in terms of discharging modes and parameter settings. Users can easily set the parameter to disconnect the battery automatically when it reaches a preset voltage, thus preventing over-discharging and extending battery life. With its customizable parameters, this battery controller allows users to tailor their power management system to their specific needs and preferences.
- MEMORY FUNCTION: With power-off protection, it will save your settings in the event of an unexpected loss of power. This feature is crucial for electronic devices that require specific configurations, as it prevents the loss of critical data and allows you to resume work where you left off.
- DELAY TURN-ON: That means, after a disconnect, the interval between turning on again. The time range that can be set is 0-999 seconds
- PARAMETER: Board Size: 57 x 42 x 19mm/2.24 x 1.65 x 0.75inch(L*W*H); Input Voltage: DC 12-36V; Accuracy: 0.1V; Power Consumption: <1.5W; Maximum Amperage before Breaker Trips: 20A

## Questions & Answers

**Q: What is idle current draw when low voltage disconnect trips?**
A: Less than 1.5 watts per advertised specs which would be about 0.1 A (100 ma).

**Q: Can this be used with AC power at inverter output? I am thinking of wiring this into a small extension cord to have a "protected" circuit.**
A: Yes..BUT.. you need a 12 volt DPDT relay between your inverter and the load . Your DC 12 volts going into the inverter will also go into this Voltage Protector and the output from this Voltage Protector will power your  DC 12 relay.  When the 12 volts DC voltage going into the inverter drops to the set low voltage it will disable the relay which in turns cuts off the ac power between your inverter and your load.

**Q: What is the maximum amperage for this item?**
A: The maximum amperage before the breaker trips is 20A

**Q: With this work with dewalt 20v batteries?**
A: For posterity and because this question is popular: program at 15 Volts
5-cells * 3 Volts = 15 Volts
At the absolute lowest, down to 2.5V per cell. But I don't recommend that for safety or longevity.
I don't see anything in the description advising against Li-Ion batteries. Nor can I think of any reason this would not work for Li-Ion batteries, provided you program the shutoff correctly.
