Does anyone use a wireless battery monitor while dry camping?The ridiculous wired one that was installed on my TT with the standard four red dot lights is pretty inaccurate.I see THIS ONE from Walmart that uses your phone and was wondering if was any good.Or are there other better options out there for someone who's lazy and doesnt want to have to put the beer down and get out of the camp chair to see if I 'really' have to start the generator.

I have used quicklynks Bluetooth battery monitor II (#APP-BM2) on my last two rv’s very reliable,easy to install and the app works great , available on Amazon $35

Interesting, in the Amazon Q&A the vendor says it can even be used to monitor solar panel output as long as it's 12V. It might be helpful in trouble shooting so you don't have to go up and down to the roof or from one end of the MH to the other to check the mounted gauge.Bill P.

Your link isn't working. If this is it:Bluetooth 12V Battery Monitor, iOS & Android Compatible- Accutire# MS-51It should work fine.

Be aware it uses a button battery--not power from the battery bank. The negative reviews on Amazon would give me pause to buy this.

Here's a link from another thread.

We have the Victron BMV-712 (bluetooth) and while a lot more expensive than that other one listed, and install is a little more involved with the shunt, but I think its worth it. Very good battery monitor with a ton of functions.

I use the Victron BMV monitor. Works great and with a Bluetooth dongle you can monitor your battery from your phone.

I'm going to to the same.

To the OP, what you really need is an AMP HOUR monitor such as the Xantrex LinkLite / LinkPro or the Victron BMV712, or a Trimetric amp hour monitor.
Anything else is not going to give an accurate level of charge on your batteries.

The product you linked just looks at voltage and then lights up a corresponding number of bars in a bar graph, which is just a glorified volt meter.

With respect,

Amp-hour counters don't give an accurate level. They are better than a volt meter.

And you think that why? If you program in the Peukert constant like the Victron has, you can be very accurate. The % of SOC may not be accurate as that is a moving number but the amps removed is very accurate.
