Looking for input how anyone reduced the heat of a FWF battery. I made the mistake of putting mine on the side opposite stock location but lower. Seemed to be a good location as my FW is pretty cramped. Yes, takes up just as much room higher than lower but was saving the upper area for equipment I considered less heat tolerant. When installed was early in the kit cycle and did not have the benefit of prior experience. I knew heat could be an issue, so I have a thermocouple in both batteries to monitor the situation. I started flying it Sept in Ohio and took it down to Florida November. It's been in paint since March and now flying it more this time in the South as we are spending more time there now. Situation not going to get better for my airframe. Yes, the internal battery temp alerts are also telling me that after 30 to 45 mins they don't like the temp being operated at. I have tried wrapping the battery with insulated (~1/4 inch) material with reflective tape. Little improvement. Added a blast tube, little improvement. I'm using the standard 5/8 blast tube, if I go a little larger any help? It appears that even using the Earth X box that is designed for higher temps just going to delay the issue. Might help when I shut things off. Anyone have any luck adding some sort of barriers on the exhaust tubes? If so, did that help? Moving the battery would be a major PITA. Any input for the blast tube location considering the battery sit behind the exhaust? Thought maybe might be more effective locating blowing down the top but maybe in front would disperse the radiant heat more efficiently.
