Reading about spontaneous fires scares me. I want something stand alone in my shop that doesn't require moving them. It would be nice to be able to charge without hovering over them. My time in the shop is limited with two small kids. I've posted the pics of the fire safe that got cooked here on RCU before, can't find them to repost. Scary how a tiny little pack just destroyed it.

Grainger has some enclosures that would work well, but I think I'm gonna make my own.
