I operate a battery for my WFP system which is wired into my main Tranny Connect's battery through a "split" relay. I'm no techie, but as I understand it, as I drive round my main car battery charges the other.
I need a battery box (I think) as the battery - although quite chunky - can move around in the back of the van. I need a fixing bracket and some kind of water protection as my brush sits just above it.
Any brilliant ideas please?
