You can use a battery charger such as the NOCO Genius Battery Charger and Maintainer # 329-GENIUS5 to charge a set of batteries that are wired in parallel however, the first battery will charge first. Once the first battery is charged it will then provide a charge to the second battery. I will say that charging the two batteries separately will be the fastest way to charge them.

Hi. I am trying to hook my caravan up with 2 12 volt batteries. I understood how to hook them up and charge. Cause of the tight area I ed to use the most flexible wire, hitch mostly means lower a page. What is the right size wire I can use. I don’t want the wire too stiff s it may rub in the area

When wiring up a couple batteries together you really need to use pretty heavy gauge wire. Obviously as wire gets thicker it's not as flexible but going with smaller wire could affect voltage output. I think 6 gauge wire is the smallest I would go.
