Usable capacity of batteries

But with the hot air removed, cooler air will cool the interior.

Yes, but you need to factor in some thermal dynamics.

What is the ability of air, at temperature A, to remove heat energy from the selected bus enclosure, which is heated to temperature B, and that internal bus structure having a mass of X pounds of mass that must have its heat also carried away, otherwise, the incoming cool air at temperature A, quickly rises to temperature B, and the air exchange must be repeated/continued, until all the temperature B interior structure has been cooled to temperature A, incoming cool air.

BTU, British Thermal Units, are the units that the air has to carry away, and the bus interior structure will be giving off.

Keep going!!

happy coaching!

The biggest difference so far was white painting the roof. Max 140 inside down to 108. The powered vents reduced that to 104. At this point I think I'm probably reaching reducing returns.

Once I've got the power supply working properly, the next stage will be to put removable screens in the window when needed...
