Solar cable sizing

Hi Guys,
I have absolutely no experience with electrics at all and was hoping for some advice.
I have two 100w solar panels hooked up in parallel with combined amps of 9.82 will a 6mm2 cable be large enough for connecting to the solar charger and to the battery?
I’m only looking to run a few led lights and around 4/5 usb socket plugs in the van and won’t need 230v mains electric.
Can someone please give me some advice on what sized wires in mm2 or mm would be best for this very simple electric set up?
And if I should be using twin core cable or two separate cables?
If anyone could help I would be very appreciate I’ve been driving myself mad with it all day. Thank you, Anna.

Yup should be fine, don't forget to fuse them once inside the roof and also at the battery end, and attach the controller to the batteries first then after a little while connect the panels.
