I installed lithium batteries on my golf cart and the old gauge would not work. Replaced it with this gauge and it worked fabulous. Easy to install and very accurate according to my meter. The only problem is that it is extremely hard to read in the daylight. But I had seen that in the reviews. It is still legible, just not real bright. Overall a great buy.

I cannot overstate how vital this little display has become to me. I live off grid, and frequently have my camper plugged into my rig. It was a common thing to guess how much power was left in my truck looking at the analog meter in the dash, and often my truck would die before I realized it's actual level. I put this display right in the front and center on my center dash now I always know exactly what is going on with the power. It's responsive to all the powere being used in the system, it's bright, easy to install, and I've checked it against my multimeter and it's right on. Here's a user tip, if you want to keep it mobile instead of mounting it, use alligator clips on the ends of your wires then you can use it to check other batteries like drill batteries, mowers etc. Absolutely a 5 🌟 product. This can save your battery, and your time. Thank you.

I like the fact that it was easy to install and quick. I wish the included wires were longer, but that's not a big deal.

It's nice! Pretty accurate, the light is bright but not enough to be annoying at night, and it's well made. I can't comment on the plastic frame to mount it, but the voltage reader is exactly what i needed.

I wrote a great review after installing this item. Unfortunately it broke on me less than 24 hours later. So I am changing my review. I attempted to remove the wire (it uses the common male blade and female receptacle) to change the mounting location of the meter. I have done this dozens of times with similar connectors on other devices over the years. In this case the meter separated and the blade came away from the connector device altogether. A double failure! Clearly this meter was very cheaply made.

Works great. Use on a 2007 golf cart. Battery kept going down. Could not tell what the voltage was. I have a gas powered golf cart. Club car cannot tell when the battery was charging. This took care of my problem. It shows when the generator is charging now. Highly recommended.
