Black battery box repainting

[Ukrainian_Kozak]

I'm preparing to my first boondocking in the desert environment and questioning why the plastic battery boxes are made from black plastic (my batteries are mounted outside near the hitch) won't it cause some overhearing from constant sun exposure? Would it make sense/help to paint it white or silver? Anyone had any troubles with batteries overheating in the sun? I'm planning to top off the batteries during day time from 100w solar setup.

Living in the Desert and the heat for most of my life, I can say that batteries hold there own. Direct and indirect heat generated under the hood of a car or truck can easily exceed 100-125 degrees in temperature or more. Follow the care instructions associated with your battery and enjoy boondocking.
