Heat ! - Idea's for cooling a pelican case on a boat. 2xT200

Hi folks. Boat #1 2xT200 @20V cool as and doing 8km on 12Amp Hours - very happy.
Boat #2 Bigger ! 2xT200 @12V Way too hot !! Same Config - Basic ESC x2 and Pixhawk.
Any great idea’s for cooling a waterproof electronics box ?? Im hoping to not pump water around …
Thanks in advance.

Hi @KiwiPaul,

This comment covers some previous answers.

If you’re not able to shade the enclosure, it should at least help to make it a light/white colour if possible :slight_smile:
