I would like to connect my 2 8AH batteries to one Solar panel for charging while the glider is in its trailer. I will use a controller and I have 2 separate sockets in the glider-one per battery.

I thought to simply split the wires coming out of the controller to the two batteries/sockets but I came across this:

Any suggestions?
