Battery Low Voltage Disconnect Module MPJA Inc 37619 MI HWC-M635

Non-isolated, DC voltage disconnect relay module for preventing over discharge of lithium and lead-acid batteries. Adjustable cutoff and reconnect voltages. Relay opens when Input voltage drops below set limit, closes when input reaches the adjustable restart value.
0-10 minutes Adjustable reconnect delay.
Rated: 12-36V Batteries
Max Voltage: 60VDC
Relay Rated: 20A max @ 14VDC
Output voltage: same as Input voltage
Control Accuracy: 0.1V
Power consumption:1.5W

This is the video vendors should link too when trying to explain how to use this circuit. Great video!

Super helpful! Just recapping so I remember
1. When holding left plus button can calibrate voltage
2. When tapping plus button once, low voltage cutoff shows. If double tapping after voltage cutoff then can set the cutoff
3. When tapping minus button once, can set the voltage difference until next turn on
4. Red light indicates power is flowing to the end

Ive had this module for 2 years. I thought it was faulty. Now it seems so simple. Thank you

[alco_cactus]

Thank you, honestly couldn’t figure it out myself!

[reignsadventures]

Thank you, I finally understood the last option (time delay).

[Scott-sxqq]

thanks. very to the point. exactly what i was looking for

[robertovizcarrondo]

I’m new on this and this info is really really helpful thank you so much

Hi, what happens if the input is disconnected- will it restart with the saved values when reconnected?

[fabioeleuterio]

I bought that module, but it's not retaining the settings in memory when the power is off. Could work for me but I had this issue...

[bvdvoort]

could the module stil discharge the battery lower then its set cut of value when the module dissconnects from the led? Because the modual display is still on. If so could this Module still distroy your battery by discharging it to the bottem?

Can you disable the screen while not in use

Hi, great video, I bought one on these to use on a car cigarrete lighter that is always on (2005 Ford Fiesta) 12v battery. What should be the best settings where the idea is to keep devices connected only with the car running. What should be the ideal configuration (including the volt hysteresis)? This info would be very appreciate as I do not have a multimeter right now. Thanks in advance!

is there a way to reset the factory values?

[wesleyberg]

How would you wire these for two batteries in series?

[adamsisernik]

I have two LifePo4 batteries, Basen Green 11.7kWh 51.2V (BG), and Ecoflow Delta pro - inverter 48V 3.6kWh (DP). I use BG to charge a DP battery via XT60 solar input (400W 8A). With the DP application, it is not possible to set the BG not to be completely discharged? Would be such adjustable 48V DC Over and Under Voltage Monitoring Protection Relay suitable for my batteries, so that voltage limit (under 51V) will stop charging DP from BG battery?

Does anyone know where Milwaukee batteries cutoff voltage is to keep from discharging to low?

[DadiszFekete]

what could be the problem if the relay stays closed? (led is off)

I have one of these I connected for my son's Power Wheels. I'm using my 20/18v DeWalt batteries and at first it was reading the voltage from the battery correctly. It was showing anywhere between 18-20v. However, after a few uses I noticed that the display on the low cut-off protection board jumped all the way up to 99.9. I have a separate display device in the loop that also displays the voltage, and it is showing at the correct voltage amount. Any idea why the protection board default display is at 99.9? The cut-off value is set to 16v and the difference value is set to 1.

Can i disconnection set at 11.5 volt in this module while using a 12 volt 7 ah lead acid battery as imput? Please reply.
