Apart from maybe the cool factor would these actually serve a purpose or simply snake oil? http://www.hobbyking.com/hobbyking/store/%5F%5F21192%5F%5FBlue%5FAluminum%5FBattery%5FWater %5FCooling%5FBoard%5F2pcs%5F.html

Snake oil. If your batts are getting hot than you are over amping them. There is a limit!

Thats funny considering I preheat my batteries this time of year. I guess if it is real hot outside they would do something.
