Works nice, switches to power supply when battery is low. I bought two.

The power switching comes with a small drop and it is not continuous as I hoped. It does power over to the batteries and back to main power.

I use these as a backup power system for my cable modem and router . I have a 43 U computer rack at the bottom of the rack I have two large lithium 12 V batteries that’s charged by multiple solar panels outside . So I use these boards as a backup power system from those batteries to my cable modem and my router work fantastic . Much better set up then a UPS .

If power went out, battery backup to warming pads to keep an outdoor pipe from freezing.

Power goes out when switching from Vin to battery. Only seems to happen under load.

I just got done installing this module. Installation was a breeze. However, after connecting both power sources the green light and red light both remain lit. If I turn off the power supply, both lights stay lit. If I disconnect the battery, both lights still stay lit.So, something is not right.But the listing doesn't allow questions to be asked . So I've got to leave a review in order to see if the seller knows what would cause this.
