## Overview

The ICSTATION Low Voltage Disconnect module is a smart battery protection board designed for 6V-60V lead acid and lithium batteries. Featuring a 30A relay and a high-definition LCD, it offers precise charge and discharge control with customizable parameters and delay turn-on settings to maximize battery lifespan and performance.

## Description

Full description not available

## 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. In addition, if you have any questions in use, please let us know.
- CHARGE AND DISCHARGE PROTECTION: You can choose the charging or discharging mode and set parameters as desired. As an example, the module will automatically disconnect when the battery voltage reaches the predetermined level to prevent over-discharging and extend the battery's lifespan. Furthermore, you can also configure the charging and discharging time according to your requirements.
- LCD SCREEN: In contrast to other LED display modules, this protective module includes an LCD high-definition screen that can accurately present voltage levels, percentage of voltage remaining, and time.
- 30A CURRENT: With 30A high current relay, suitable for any 6-60V variety of batteries and Lithium batteries
- DELAY TURN-ON: That means, after a charge or discharge, the interval between turning on again. The time range that can be set is 0-999 seconds

## Questions & Answers

**Q: Is there any way to dim the LED so it's not so bright?**
A: see my review below for explanation but yes. if you can do a little soldering. 

on the back of the board, marked "R2" a resistor labeled 330. remove it. replace with 330 ohm 1/4 watt resistor. the resistor feeds the backlight. the original labeled 330 is 33 ohm. the new is perfect in my opinion. not too bright but light enough to easily read.

**Q: What gage wire can fit the connectors?**
A: if you simply stick wire in around 12 gauge. if you use a fork spade, 10 gauge otherwise itll be a wire Frey mess

**Q: If this device gets wired between the battery and inverter wire the wire so thin?**
A: I only use only a small device 75 watts.

**Q: Does the device retain settings when power is removed?**
A: Yes, however you have to go back through a small start up sequence if power is completely disconnected.

### ⭐⭐⭐⭐⭐ Instructions in English...

Instructions in English:🔘 Button FunctionsUP ButtonShort press: Switch between percentage display and time.Long press (5 seconds): Toggle between charging mode (IN) and discharging mode (OUT).SET ButtonShort press: View current parameter settings.Long press: Enter parameter setting mode.Set the following:UP: Upper voltage limitdn: Lower voltage limitOP: Conduction timedOP: Delay conduction time (0–999 seconds)FOP: Forced conduction time (discharge mode only, 0–10 seconds)DOWN ButtonShort press: Toggle relay on/off (emergency stop). When disabled, the LCD displays “OFF” and the relay is disconnected.Long press: Set LCD backlight mode:L-P: Backlight always onON: Backlight auto-off after 5–10 minutes (press any key to wake it up)🔋 Mode DescriptionsCharging Mode (IN)When battery voltage ≤ dn (lower limit), the relay turns on and charging begins.When battery voltage ≥ UP (upper limit), the relay turns off, ending the charge.While charging, the relay is on and "IN" flashes.Discharging Mode (OUT)When battery voltage ≥ UP, the relay turns on and discharging begins.When battery voltage ≤ dn, the relay turns off, ending the discharge.While discharging, the relay is on and "OUT" flashes.⚠️ Note: This device is a simple voltage controller. It uses a relay to switch output on or off. It does not regulate voltage or current—only on/off switching.⚙️ Parameter SettingsEnter Setting Mode: Long press the SET button.Navigate Parameters: Press SET to switch between parameters.Adjust Values: Use UP or DOWN to set values (short and long presses supported).Save & Exit: Long press SET again.3.1 ⏱ Charge/Discharge Time ControlIf OP (conduction time) ≠ 0:Timing begins when the relay activates.Once OP time is reached, relay disconnects automatically.If voltage conditions are invalid during timing (< dn in charge mode or > UP in discharge), the device displays H:ER to signal a configuration error.Press any button to stop flashing.If time control is off (OP = 0), the total charge/discharge duration is still recorded and shown during time display mode. This resets upon exit or the next cycle start.3.2 ⚠️ Auto Parameter CheckIf dn ≥ UP, the device will display ERR and not operate.3.3 ⏲ Delay Function (dOP)Delay time between a completed cycle and the next relay activation (0–999 seconds).3.4 🔄 Forced Relay Conduction (FOP)In discharge mode, when conditions are met, the relay forces ON for 0–10 seconds, allowing for voltage re-checking.Useful when test loads cause a false low-voltage reading at the start of discharge.

### ⭐⭐⭐⭐⭐ Simple and dependable battery monitor for automated charging.
*by A***R on July 23, 2025*

Simple device that will disable battery discharge at any settable voltage point, or be used as what it was designed to do, monitor battery drain and automatically charge to a set point. Works great and has features to set timing of active charge and discharge resets

### ⭐⭐⭐⭐ Not sure how many stars this deserves.
*by M***D on October 6, 2024*

I saw some other reviews saying that this switch didn't work. It definitely isn't plug and play. It took me a minute to figure it out. Which can be difficult since the users manual is written in broken english.My issue was that as I was using it to protect the over discharge of my batteries was that I assumed the upper voltage limit was supposed to be above my supplied voltage. That won't trigger the relay to supply power. The upper limit needs to be set below supplied voltage. And the actual lower voltage limit.... I'm not sure what that does yet.It should be noted that I'm not familiar with these types of electronics.
