PRODUCT 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 at the first time.
【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

low Voltage Cutoff 12V Disconnect Switch

What can we do?

ICStation has 11 years experience in electronic industry products
Provide technical assistance
Take charge of all defective items
Looking forward to your inquiry and hope to build a long term cooperation relationship with you!

protect battery and prolong battery life

Compatible with 12-36V lithium and lead-acid battery. This is a relay module, not included any battery. Only suitable for a single battery, not for a battery pack.
When the battery voltage reaches the predetermined disconnect voltage, the module will automatically disconnect the load to prevent over-discharge of the battery and extend its lifespan.
Support delay 0-10 minutes to reconnect
Reliable and easy to set up

Input Voltage Range: DC12-36V
Control Accuracy: 0.1V
Compatible Battery: lead acid, lithium ion battery, solar panel battery
Board Size: 57 X 42 X 19mm/2.24 X 1.65 X 0.75inch(L*W*H)
Packed in anti-static bag

Instructions

Double press the “+” button, and when the decimal point is flashing, press the “+” or “-" button to set the disconnect voltage.
Double press the “-" button, and when the decimal point is flashing, press the “+” or “-" button to set the difference value.
Long press the “+” button, and when the LED screen is flashing, press the “+” or “-" button to calibrate the input voltage.
Long press the “-" button, and then press the “+” or “-" button to set the delay value T. That is to say, when the output voltage reaches the reconnect value, it will delay T minutes, the load reconnects. The delay time range from 000 to 010 minutes, and it displays like: 000 or 001 or 005 or 010. Note that no decimal point is displayed at this time.
Press the “+” button to view disconnect voltage.
Press the “-" button to view difference value.

*What is the "difference value"?

The value between the disconnect voltage and the reconnect voltage. That is to say, difference value = reconnect voltage - disconnect voltage

For example

1. How to set if I want it to stop outputting when the voltage is lower than 11V and start when the voltage is over 11.6V?

Double press “+” and the LED starts flashing, press the “+” or “-" button to set the value as 11V. After the flashing stops, double press “-" and when the LED is flashing, press the “+” or “-" button to set the difference value as 0.6V.

2. How to set if I want it to stop outputting when the battery voltage is lower than 12.5V and when it is over 14.8V, it starts outputting after 2 minutes?

Double press “+” button to set it as 12.5 and then double press “-" button to set the difference value as 2.3 (because 14.8V-12.5=2.3V). And then press and hold on the “-" button, set T=2.

Why it doesn’t has output when I first connect it?

For example, if the disconnect volt is 9V and the difference value is 5V, then:

When first connected, if the battery is lower than 9V, the relay is disconnected;
When first connected, if the battery is higher than 9V but lower than 14V (9+5), the relay is disconnected;
When first connected, if the battery is higher than 14V(the reconnect voltage), the relay is connected;
During use, the module will be disconnected when the voltage drops to 9V, and will be automatically reconnected when the battery is charged to 14V.

Something You Need to Know...

This product works great to cut off the voltage when a battery discharges to a set level. It stops the output/load but you can NOT leave a battery hooked up to this product. This voltage cutoff (this product) stays on and will continue to drain the battery as this product (understandably) needs electricity to operate. True, this product will drain the battery much more slowly than your load was probably draining the battery, but make no mistake, this product consumes electricity after disconnecting the load and gets that electricity from your battery, eventually draining it.
It can only work with a single battery, not work well with the battery in parallel(battery pack). Most big batteries are made of many small batteries inside, such as Mil-waukee/ De-walt battery. So we don't recommend you to use it with these batteries.
