Lipo guru's please help
 

I am looking into buying a new charger so that I can charge multiple batteries in parallel. I was wondering how many 2s 5000mah or better packs could a 200watt charger charge with at least 4-5amps rate? any info on this would be great....

Unless all the packs you are trying to charge all start at the some voltage then you could be doing undue damage to the packs. The instant you connect any two packs in parallel current is flowing to bring the lower pack up in voltage and dropping the higher pack. With lipos and a large enough voltage differnece there could be quite a few amps being swapped between the packs. Unless you are running the packs in parallel to begin with so they all end at the same voltage, I would not suggest connecting packs of various discharge levels in parallel.

To actually answer your question, about 4- 5 packs.

thanks and yea I know they have to be very similar in voltage I pull my packs off my truck and they're usually 7.4-.5 volts a piece

5A on a 2s pack would use just under 50W. Hobbyking has 2 chargers that will charge 4 packs independantly, each with 50W output. This would be much better than trying to charge them parallel on one big charger.

Which battery would that be? I am looking @ getting something like that since I want to charge my 2s batteries at one time.

This one is just like having 4 separate Accucel-6 chargers in one unit. For this unit, 4--2s packs of about 5000mah is about as large a pack as you can charge at 1C. It will work just fine on larger packs, but charge time will be increased.

hmm I'll have to look into that 2
