Is there a max ambient temp lipos should be kept at? Saturday at our track the temp was about 105 degrees and we had two lipo packs that were just sitting around the pits "inflate". The inner metal pouches seemed to pressurize to the point the plactic cases popped open and the packs became unusable. One of them wasn't even being used, just being stored in a guys pit box. Very strange. Has anyone else seen this? I assume it is temp related.
