i placed it under AUTOMOTIVE ! where should it be?Moved to the correct section!
fair enough,difficult to know that without your instructions.As I said to you before, automotive is in the projects section, it's not for general car chit chat!
It's meant for build threads and discussions about projects only.
Brew room, intelligent off-topic stuff, social club, off-topic crap.
I have never been a fan of split charging batteries because one is always the dominant one, and stops the less dominant one from being fully charged .
I much prefer one charging unit per battery,or disconnecting each for a timed period,
but the best is the more modern way of getting a 12v to 12v smart charger which ensures the second battery is FULLY charged.
That is not a good option, it is a crap way even with shoguns and the like that had twin batteries as standard, I have converted loads of them to one battery, as two does not work long term you ALLWAYS end up with one battery weaker,even if the cables are identical lengths (VERY important) if one battery fails you have to change both and they have to be identicle to even stand a chance.The other option is to hook them up in parallel with an isolator on the second battery
