Maybe its a bit much but with all the kit I got in Audrey that uses power and my paranoia, I started thinking about 2nd batteries or battery backups.
One was a secondary battery and split charging but I can't think where to put it.
The second idea was mounting some external terminals in the engine bay and connect them up to a leisure battery when I'm stationary for longs periods of time and want to watch TV, A film or use the projector.
I think the leisure battery would be a better idea over split chartering. I don't mind carrying a 2nd when I know I'll need, like shows or camping.
My concern is what damage or problems I might have by connecting a large leisure battery to my battery/car leads.
Any one got any thoughts?
