E-REVO battery temps.

[E-Revonut]

My question is what is everyone doing to help keep battery temps in check with the new E-REVO chassis? Staying out of the grass for the most part has done wonders at bringing my temps down more than 10* but would still like to do more. I have started by cutting the fins out of the ducts at the front of the compartments. Holding a fan in front of the servo I noticed that there wasn't much air getting in, after removing the fins I'm getting more air flow. Is there anything available that would allow me to do something like NASCAR does running ducts to their brakes? A way to hook up a fan with some ducts coming off going to the battery compartments? Has anyone mounted a small fan to the opening? Open to ideas and would love to see pics if anyone has done anything. After I run mine again I'll post temps, today it was 80-85* out and after a 20 minute run my packs where 112-115*.
