I also think if the battery cover itself was insulated it might help. put some aerogel in between two pieces of plastic.

I may try, my concern was it would also keep the heat in the box. Seems like the battery has a real tough time to cool. I will experiment.

As long as they don’t seal the battery cover it would still have room to escape like it does now. I was considering sealing my cover with a rubber seal when I first got the unit. They said it would be fine to do, but now I’m glad I didn’t.

So been thinking about this too. So you know I did the mod to protect the antennas. Was thinking of tape, and paint or something on the plexiglass I put on like a hat. Protect the antennas, and if so open the lid let some heat out. Well I’m researching so tints that would stick to plexiglass. Not all tints will, like glass. So two ideas, will post others, of if anyone finds something better, please add. We like to help everyone. Now that I’m running again. So is my mind. So here it goes.
My only recommendation would be to be careful with the 3M tint because it uses metal in its blocking/reflecting material. It might impact your GPS signals and or timing and create additional multipath issues.

Yes Sir. I was already thinking about anything with reflecting material, of shine back. But if I find something that might work with the hat, and get the battery box open to more air flow. Still playing with ideas.

Does anyone have a model/stl for the battery cover? I plan to test some thermal management coatings on the cover, but would like to test a couple of different versions side by side.
I do not, but let me know if you find one.

If you reach out to support they might be able to sell you a couple. I can’t imagine they are expensive.

Sent them an email right after posting. I’ll provide an update after testing the coatings on the original cover.

Maybe they can just provide the CAD file. There’s not many trade secrets hidden in that lid

Maybe they’re trying to keep a tight lid on it!

Obligatory *groan* 
I went with this.

honestly so far the throttling firmware fix has worked wonders for me. Never stops charging, takes longer, but it keeps charging. Even in 93F weather in full sun. YMMV
How much longer does charging take after the throttling fix?
I was able to coat the cover today and installed it this afternoon right before the Yarbo went in to charge. 80F ambient and full sun, battery started out at 20% charge at 37C and maxed out at 48C from 80-100% charge.
Same experience. But only got the update today but I had to charge at 30 degrees and it kept charging. Much slower but at least it did not stop completely with an overheat error and the battery remained below 46-47 highest I’ve seen. Fingers crossed!
