I'm with Brenner, and I like the fuel analogy, which leads me to conclude, No Lipo Storage or Charging in the House or Garage.

I store my batts in vented ammo boxes, but even the smoke/fumes from a runaway 5 cell 5000 mAh lipo would ruin all the stuff we store in the garage.

I didn't see the specs on the batts in the video, below, but I don't trust such a solution for our bigger batteries. Better safe than sorry. Waterproof storage box outside here I come. Billx
