[RE-wrenches] heating lithium in cold weather

[frenergy]

Jay,

             I would think this might be pretty risky....I think of the 
difficulty in being sure all the cells were uniformly warmed.  I guess 
if they were in an enclosure and the ambient in there was held at some 
determined temp for ? (many) hours then one could assume? all the cells 
were close in temp and safe to charge.  Of course there would have to be 
some sort of regulation involved (oops I left the heater on in the 
battery enclosure last week!)
