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.

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

Works great
I read some bad reviews how it doesn't work, it works great for me pretty accurate too. You have some super nerds want it to be extremely precise to the point they are making formulas, equations and s*** in order to proof how it's not 100% accurate. It's not going in a Tesla I just need it to tell me when it's low (beer math). For you out there that are confused on how to install it well here is the simple solution. Wire the + and - straight to batteries (mine it's a 48v) the C terminal hook it to one of the wire in the ignition( the one that gives you 12v when you turn the ignition) use a volt meter I just rolled the dice on mine and I ended up hooking it up to the wrong wire so I just wired it to the other one (only had two wires I had a 50/50 chance).

Bei 12 Volt OK, bei 24 Volt geht es leider in Rauch auf.
