I've been using this http://tinyurl.com/yu8py9 for some time, it is cheap
and quality is apparently good. I say "apparently" because I've never tested
its fire-contents capabilities - and have no interest in doing that ever -
as you may guess.
But for the price I feel better charging my lipos on this bag. Additionally,
a temp detector in the interior of the bag will alarm with a big beep if the
lipo start going over 50=BA. I consider both measures enough to work with
lipos.
