Battery Capacity Voltage Meter with Alarm, Waterproof LCD Display and Backlight Digital Testers, 24V 12V 36V 48V Lead-Acid Lithium ion Battery Gauge, Fit for Car Golf Cart RV Marine (Blue)

Wiring this up is straightforward but, absolutely no directions included. You just get a gauge in a ziplock bag. What I have figured out is.#1 while putting power to gauge hold the gear button. This will put it into programming mode. By hitting the two buttons you can move between the settings and once you have them right abandon it and it will time out and apply your settings. The company finally sent me directions.

Nice display, easy to read. Easy mode switch from voltage, to % of charge, to off. Simple. I built a battery box and it was very useful to give a quick readout. Meter voltage was in agreement with another volt meter on the same box so I know it is accurate.

Quality wasn't bad pretty hard to figure out how to make it work actually couldn't make it work

Easy to use but really do t know if I would trust it. I fully charged a lifepo4 battery with charger and the best the percentage side will read is 84% for some reason. So I don’t know how much I would trust the voltage side. I mainly got this for percentage of battery are it to fo4. And s-1 also fully charged two agm batteries and same thing same percentage I wanted to use this on my overlanding solar system which is two 100 ah lifepo4 batteries running parallel so I could monitor percentage on the system. I can recommend this might have to spend the extra money on a shunt monitor

Im a 55 yr old woman who can do simple auto repairs and installing car batteries. I thought my battery was "going" its only 2 yrs old so I got this. It does show a 96% charge, but yesterday only 94% after sitting 2 days, voltage shows as 11.9 which is not good, after starting shows 14.6 which is good think it shows its NOT my alternator...so THINK not sure I need a new battery. I THINK this is accurate, just wish the pos neg wires were a bit longer but for the money mine seems to work so happy so far

You can see the voltage draw and know how much time you have left while riding your golf cart.It beats running out of juice and being towed!

Nice little meter. Put a set of aligator clips on it. Then put it on a boat battery. Works good

Easy to install and works great. It would be better if it had longer leads.
