I have just started the upgrade of the 12v system on our renault trafic autosleeper and thought I had pretty much everything covered through lots of research. I say, "thought" as something got me thinking about it again and decided to ask some advice
I'm going to be doing a total rework of the battery side of things, installing a solar panel and a two way voltage sensing split charge relay to keep everything topped up, whether from alternator or solar.
I know that it's been said many times before that a pair of leisure batteries should be of the same type and age in order to let them both fully charge and I understand the reasoning behind this. I've bought two new leisure batteries from go outdoors... 75AH and 110AH. The thing is, I didn't buy a new starter battery at the same time. Am I correct in thinking that once the split charge relay opens I will effectively have a bank of three batteries comprising the two leisure and one starter battery? If so, does that mean that I should buy a new starter battery too? The one currently fitted is of unknown age, but still showing strong charge on an LED type battery / alternator voltage tester.
Opinions please... the relay, cable etc etc arrive tomorrow
I'll do a full write-up on the electrical makeover as I go along in a seperate thread but for now, thanks for taking the time to read this
