Subject line pretty much says it all. I am putting my syncro
up for the winter and I already have a trickle charger on my
Optima for camping that is hooked right to the shore power
cable.

Can I run a set of jumper cables between both bateries and
have the trickle charger keep both topped up? Or should I put
a seperate charger on each?

My batteries are curently set up with the silver relay system
