Battery meter

Anyone have a good idea of a meter that I can put on camper that actually shows voltage of battery.

I did one of meters, from Amazon, and it failed in about one day.
So, rather than mess around, I installed a trimetric...


But, with a shunt, they are just under 200.00, so not cheap.

I installed one of these into the outlet meant for 12v TVs. $7!

You've gotten four products noted. Two do exactly what you asked for. Two do WAY more than you asked for but are probably what you need.

What is your PURPOSE in installing a meter. What do you think you will know if you simply have a voltage readout? If the answer to that is ANYTHING other than knowing if the battery is being charged at the moment...(OR if it is dead flat and can't even power the meter)....THEN you probably need one of the more expensive TRUE battery monitors. If you boondock and rely on your batteries alone for power sometimes...then you definitely want the Trimetic or Victron.

To expand on what camaraderie said. The reason I went with the Victron and not a simple voltage meter is because I wanted to know the true state of my battery not just the voltage or if it was charging. I found that the panel in the trailer is misleading if you don't know what you are looking at. When connected to shore power the panel shows full bars which just means the battery is charging (not fully charged). To know if your battery is really charged or not you have to disconnect the shore power and read the panel.

The Victron and I presume the Trimetic will always give you the true state of your battery weather charging or not. As well as the current voltage, Amp hours remaining and run time left in hour, min based on the current load.

So just something to think about before you make a purchase.

I also agree. If I was running shore power all the time, I would not have bothered with the Trimetric, but I do a lost of dispersed camping and prefer not to turn the generator. I want to know the actual status of the batteries in volts and amps, and I also like the low voltage alarm that I have set for 12 volts (a small amount under 50 percent).
