Works perfect
People have issues with this not working, they are obviously hooking it up wrong. You need to find the series in which your batteries are running. Easiest way on a golf cart is to look at which wires go from your battery pack to your run/tow box. Those wires will be your positive and negative. You can always test with a volt meter. You will want to attach positive to positive battery terminal 1 in the series and your negative at the end of the series, if you donโt do that you will not get proper reading and possibly battery meter failure. Then connect C or common to the on position post of your key switch, if you donโt do that the meter will keep scanning and give false reading or no reading at all. Sounds confusing, but Iโm sure YouTube has videos on battery series and hooking a meter up.

Works as described.
Works as described. Time will tell on longevity. Lights are bright. To bright in the dark, hard to determine what bar is lit. Note: people are complaining that the meter doesnโt read correct while charging. My oem meter does the same as it needs to be refreshed. My club car has a transport toggle switch. Just a click off and on and it refreshes the meter, no need to unplug the negative wire to refresh as others mentioned.

Less than 8 months later and the gauge is broken
My grandfather installed the gauge and it hasnโt worked well at all. I used the cart about 2 months after installing the gauge and the gauge said batteries were full and by the time I rode around my neighborhood 1x my cart ran out of power and the gauge didnโt tell me it was close to being out. In fact told me the cart was 80% full. I bought brand new batteries and got in the cart 2 weeks ago and the cart said batteries were only halfway charged. I got the electric meter out and all 4 batteries were at 12v (48v) cart but the gauge said is only halfway charged still. The cart has been fully charged the last 3 times I have used the cart but still only says halfway charged and doesnโt go down when I use the cart and go below halfway. The gauge doesnโt work well at all

Very tiny!
Itโs teeny tiny. Maybe three inches long. I laughed when I opened the tiny box!

So far so good
I had my son buy one of these about a year ago it is a little slow recovering after recharging my golf cart batteries but after having power applied for about15 minutes it self adjusts and will give a good representation of power consumed. I have not experienced that issue with the new one I put on my sonโs golf cart. These power meters are from the same company and have identical product numbers. I hope the new one lasts as well as the old one.
