I bought a computer fan at Staples to cool off my batteries. I also got a 3″ PVC pipe to set the battery in while cooling but… jeez the 8″ piece of pipe is the heaviest object in my case. I’ll go look for a smaller, thinner walled pipe. I suppose I shouldn’t have gotten a pipe rated for 270 psi, eh? But that’s all they had in 3″ pipe… Eh. I’ll figure out something.
Oh and the fan has cool purple LEDs on it. When my dad came home from dinner and saw the contraption charging in the garage, he called me Doctor Frankenstein. hehe.
