I've got a handshake deal to buy a van that has 200W of solar panels, a goalzero yeti 1250 generator thing and the owner has added a second battery in parallel with the GoalZero, so the Yeti of course now thinks it's doubled in size. If I was to add a continuous duty solenoid (because we can go for days without sun in the Northeast after all, etc), and I ran it all the way to the back (where the second battery is housed) and connect it to the second battery will it charge the second battery and the GoalZero without issue?
Thanks
