Waterproof Battery Meter 12V DC Voltmeter LED Digital Display Voltage Gauge Battery Tester for Marine Car Truck Boat RV

This is a nice 24 volt battery gauge for the price. The first one I received failed shortly after installation, but the company promptly sent me a warranty replacement, and the replacement has given me good service for many months now. A gauge like this is important where you have deep cycle batteries, because it reminds you to recharge the batteries before they get too far drained. This will dramatically improve battery life, saving you money. This was a good purchase.

Rewired an old Alumacraft and added a switch panel. The meter it came with was totally unreadable in the sunlight. This meter was simple to install a n the panel plug and play.

If you have a single battery device then it is a great product for basic information. However I installed three units on a boat start battery house battery and trolling motor. The first problem is that there is no fuse so you will have to purchase and install a fuse. Second problem is that there is no off switch so if you wire these directly to the battery they will be permanently on, if you wire it to the boat power then you will not be monitoring the "offline" battery and at the end of a days fishing the last thing you want to find is that your starting battery is dead! My solution was to wire them through relays supplied from power after the battery switch so that whenever you have a battery "online" the relays will pull in and the indicators power up when you isolate the batteries to go home then the relays drop out and the indicators power down.

easy to install, easy to read. reasonably accurate, well worth the money, purchaced 2nd unit

Nice looking voltage meter but poor workmanship. Installed on my motorcycle did a test run and found the voltage ⚡ reading jumping all over and some of the led were death.

This is a good product for play time on the boat.

So you get what you pay for. It works but there is a huge delay on the reading of the voltage. The DC audio and SMD Meters are real time. It’s not that bad of a lag but enough to annoy me but still works ok.

Easy to install, 1 inch hole in panel. The amber LEDs are a little weak in sunlight. Overall excellent product. This is on my ride-on train engine.

It didn't read the right voltage. It reads about 1.2V to 1.5V off. Pretty much useless...

I used it on my tractor to see if it charging properly

Très bien rien à redire!
