2 Pieces 12v 24v 36v 48v 72v Golf Cart Meter Battery Indicator Voltage Meter Dc with Alarm, Lithium Ion Battery Capacity Monitor(Blue)

I replaced the lead-acid battery in my camper with a LiFePO4 one. I needed to see how much juice was left in the battery, as the camper's one is calibrated for lead acid.Seems to work as it should. The instructions are a little wonky, but some fiddling around you can figure it out in a few minutes. I changed the setting to 4 Lifepo cells, which are the number in my 12.8 volt Ecoworthy battery, and the readings seem to be correct.As a bonus, it remembers your settings even when power has been disconnected. I was worried I would have to re-set it every time, but thankfully that is not the case.Well worth it for the price.

Worked well for my project. Takes a little trial and error setting up. Once you get the sequence of the button press it works fine. I mounted it in the cover of the battery box for my backup generator. Due to the size of the wires and the capability of a battery, I would recommend installing a low amperage inline fuse close to the battery positive connection. Anything under 1 amp should be fine. I used a 3/4 amp fuse because that was what I had on hand.

Easy to use

Very easy to install,instructions are not clear tho

Just a heads up it's shows 4 in the picture but u only get 2
