Thanks!
I just bought a 3 1/2 digit voltmeter from Ebay, its the kind that dosen't require a power source itself, should i go with that or make some additions?
What i basically need is a voltmeter that shows 4 digits..so i dont get the last one... i have two 12 volt batteries, brand new, never used, same brand.. to parallell, for the caravan..
The charger will be the best in the world, the Ctek, swedish made charger, plugged in whenever possible to the batteries.
I just need one voltmeter, right? to show the voltage for the moment.. the best thing would be for it to switch over to the charger or alarm when going to low.
You shouldn't discharge them more than to 10 volts or something, right?
Thanks for all the help! i'm surprised that people just help eachother this much, but i guess that's what it's like to have an interest that you burn for..
