More Power and Battery stuff
I had a brief camping trip to test some vehicle modifications. Spent 4 really enjoyable days "testing" my fridge... Still cannot get my head round frozen fish comming out of my troopy :-) The fridge was opened twice per day, starting from Friday night until Monday night - everything was super cold and still running... (National Luna 40L on a 100amp/hr battery). But: doing this is not going to make my battery last long as it is a standard cranking battery. Ideally I would like to get hold of a battery monitor that can monitor things like:
- current voltage - amp hours used I would be grateful if anyone can recommend such a device? Thanks in advance, Gil |

Found a "nasamarine" device that does it all - voltage, amp/hr consumed and put back, time remaining etc.. Looks to be ideal:
www.nasamarine.com/Misc/bm1.html should be handy to avoid destroying batteries! As well of course as having the vital gadget appeal of a big LCD back-lit display :-) Gil |

I've used a digital volt meter for a few years and it is very reassuring but that extra information is better - good find. Ofcourse you need one for each batterry.

This looks like a good thing to have. I'm confused though as it mentions in the product PDF that the meter cannot monitor a starting battery. So you need another device to do that?

Cheers for the replies guys! To be honest the starting battery is not what concerns me - why? Well the aux battery is what will get drained when parked up, by fridge and lights or whatever, and as my starting battery is in fairly good condition and will not be affected by any discharge from the aux system then I would only want to monitor the aux one. I suppose if it was really desired it would not be too difficult to install a second shunt and a switch system to check both batteries (but probably only voltage as I would imagine the 'memory' of what has been discharged would be totally wrong if switching between two batteries...)
