how do you monitor trailer battery voltage?

[shawnzy]

Im just wondering if anyone put a voltmeter gauge on the trailer somewhere to keep track of battery voltage?? I had the battery run out from putting the slide out 3 times other day, so I plugged it in to charge it up maybe it wasn't fully charged when I purchased it?? I just don't want to ever forget about it and run out because my jack is battery powered..

Thanks

I have a DC and a AC meter. I picked up ones with blue digital readouts on Ebay for around $5 including the shipping 2 yrs ago. I mounted them in a kitchen cabinet panel just inside the entry door. There at eye level from outside the 5er and the blue light makes a nice night light for the steps into the bath/bedroom.
I wired in a on/off rocker switch. I leave them on most of the time. The 5er's been plugged in here at home for 2 months and they've been on the whole time.

This is the unit that we have installed.

Universal 12v Digital VoltMeter

My monitor panel includes a battery condition/level meter. I think it probably is 13.5vdc for top mark, 13 or 12.8 for 3/4, 12.5 or so for 1/2 and the bottom is 12 to 12.4, after that it probably doesn't register.

Yep, I use the older version of this brand:

Some permanently install a digital meter in wall inside their TT. That's what I eventually want to do, as well as a digital 120v meter to monitor CG voltage.
