Yeah, but you can buy packs already wired in parallel.  The key should be
to 
have them at the same voltage level before connecting the leads.  Another 
RCer told me that they connected a 4.2V cell and a 3.8V cell and only had
5A 
flow between them and it diminished quickly.  Alghough I don't recommend
any 
connection that would cause cause more than 1C current to flow into a
cell, 
I don't think paralleling equal voltage cells would be any more dangerous 
than charging LiPo's is.  However, if one pack would go bad, it may be 
relying on the fuses to protect the other packs.

I think I'd be better off with a multiple (4 or 5) ****t charger that has 
250W power like the Hyperion 0610i does.  I wouldn't have to match the
cell 
voltages before connecting.  Just trying to come up with an easier way to 
handle multiple packs without lugging around multiple chargers.
