Thunder power has a new dual charger. 10 amps per port
turnigy makes one that, if im not mistaken, charges 4 at a time
I have the same problem. I just ordered two Zippy Flightmax 3S 5000mah 30C Lipos from Hobbyking which will be in Friday or Saturday, but now I need a charger. I was going to buy the iMax B6 charger and the double 3S port connector from hobbyking but shipping is $18 and it won't even be in for a week or two!! So I decided no on that. I need a charger around $40-$50 that charges two 3s Lipos at once.

sorry the only multi lipo charger i found was for 99 bucks but it can charge 4 batteries at once and many different kinds at once too.
like a 2 lipos and 2 nimh like that.
guys i found the answer venom makes a dual port 10 amp per port charger for 100$ and then hobbypartz.com has a power supply that has plenty of "w" for the charger for only 45$ so you can get a sexy charger for only 150$

Go with two of the Thunder AC 680 pros, why two ...well if you haven't already ordered the ac to dc power supply ...the Thunder which I have one and will say money well spent...has a cooling fan keep it cool while charging and is 10 amps and at the price hobby partz is selling these for you could get two for under 120 and if one breaks you still have a back up
