Portable suitcase solar panels
I looking at getting a 100 to 130 W suitcase solar panel top off dual 12v batteries while dry camping and have some questions: 1. do you connect to the 7-pin trailer cable or attach wires directly ...

I have one, it has a built in controller. You connect to the battery via some battery jumper cable clamps except smaller versions. If you have 2X6V then connect across both. For multiple 12V I'm not sure. It does work. As for monocrystalline I've been told there is little effective difference between those and the amorphous type. But I'm no expert.
