Yep, I was guilty of that, especially regarding solar panels. This is one reason why I downgraded to a simple 4 bar LED "battery condition" thingy ;)

Very wise. Forum is already full of proclaimations on 'how many amps' on solar. Can become an obcession akin to those that invest heavily in 'high-end' stereos who then go on and on about frequency response at any opportunity - and completely forget to just damned well listen to the music. :D

I have a switch where I can turn the display off if need be!

Worth sticking you meter in line with the feed to the meter(s) and see how much power they consume. I have one here (green led type) that uses more than you would expect (it's not in the van). Mind you, I am guessing you will only be switching them on when you wish to make a mental note of state of charge, so battery drain when parked up won't be an issue then.

This looks a bit funky - bloomin expensive though:

I fitted mine where the "posh" vans have their hand-brake warning light. I know it's not Fluke meter accurate but if it ever gets below 12V I know I've got a problem

I bought and installed this in my van. Installed in the rear, to enable the kids tablets to charge (primarily), run a portabe DVD player on journeys but also has a voltmeter. I generally only use it when the van is running, but I can keep an eye if we are using whilst stopped (I don't have a leisure battery!!)

I'm planning of buying one of those to mount in the front dash so I can also operate a sat-nav and have bought one of these http://www.ebay.co.uk/itm/262688593914" onclick="window.open(this.href);return false; to mount in the back on the leisure battery circuit..

That way I'll have 2 volt meters, one for each circuit..
