are their size the same as NiMh Sub-C?

MB Racer,
FMA Direct sells the 3270MAH 7.4V pack for around $75 and I could get a 4800MAH 7.4V for around the same price. I've seen 3300MAH NIMH packs going for way more than $75 and with lithium you get an extra 0.2 volts. also, depending of the application, some people even rate the lithium at 4.2V a cell.

Not this ones. They are 12000mah and they have a continuous 10C discharge and that is 120amps. Most speed control/motor combo will draw about 40-70 amps.

STOP CHARGING WITH THAT PACK NOW!!!!!! IT is EXTREMELY dangerous for you to be charging a Li-Po pack with a charger NOT designed for it. The Li-Po REQUIRE A Constant Voltage/Constant Amperage charge to be safe. If you exceed the voltage limit of the cell you will have a huge problem!!!!!!! The cells are charge by first a constant amps (until the cell max voltage cpacity) then it switchs to constant voltage and slowly drops the amp rate down to zero. This is the ONLY safe and Recommended way to charge these packs. DO NOT CHARGE THEM AGAIN WITH YOUR SUPER BRAIN!!!!!!!!
Do yourself and the fire department a favor and get one that's designed to charge it!!!!!!!!!!

actually
Its not.The language MRC use is deceiving.If you so choose to keep using this charger without the safety precautions that should be built into in{they are not}then be ready to get hurt,burn yourself or your house down or worse.Be warned.When that battery explodes from you using this charger then when you go to sew MRC,they already covered thier own rears because they know that this charger cant safely charge li-poly batts.They didnt say it couldnt charger it,but safely chrge it is something different.

Your best bet is to talk to Steve Hill from www.battlepacks.com. He has been working with these batteries and can suggest the proper chargers for them.

I used the super brain once. Now with the new info I should shop around for another one. I used the Triton at my local hobby store and it timed out twice, but it didn't fully charge one of the packs. I'm looking into either a Astro Flight 109, Orbit or Schulze. Thank you all for warning me about the super brain 969.

how many 5 minute runs do you think you can get out of it with a novak brushless?
