In theory you could charge 4 LiPo packs in parallel off the same
charger if 1) they're all the same number of cells (this is vital!)
and 2) are all at approximately the same voltage/charge level when you
start. Ideally all the packs involved would be identical, but this
isn't absolutely essential.
However, there are some dangers. Violating #1 will almost certainly
destroy at least one battery and could cause easily a fire. Violating
#2 will cause high currents to flow if the voltages are signifigantly
different, and this could destroy a battery or start a fire as well.
Beyond that, there's also a danger that a battery pack with a much
lower internal resistance will get most of the charging and so you
could charge it at too high of a rate ...
So I would not suggest trying this unless you know what you're doing
and understand the dangers.
You can also charge two or more NiCd/NiMH packs on one charger by
putting them in series, but similar dangers/concerns exist. Again,
don't do it unless you understand what you're doing.
Personally, I have two Triton chargers. Usually one stays in my car
and one in my garage, but they are portable, and if I think I'll be
doing a lot of charging at the field, they'll both go with me. Having
two chargers and at least three battery packs and somebody to talk to
usually means I can fly all I want, and yak about flying in between
