A 5000 20c lipo should be able to output around 100amps. That would not be enough for an 1/8 MT geared for 45mph on 4s, you need 150amps or more for 4s useage with that gearing. Now on 6s those cells should be fine.
Look at it this way, a 4s 5000 20c lipo can do 1480watts (theoretical max, no losses factored for this number) at 75% it can do 1110 watts, or 1.5hp, not enough for a 12lb truck with tall gearing.
A 6s 5000 20c lipo can do 2200watts, factor in about 75% effecientcy, and you have 1650 watts, or 2.2 hp. I would not run a MT on 6s with any cell spec'd lower than the 5000 20c you mention. Unless you plan to run 35mph, then you can run less capable cells (maybe even maxamps).
A 12lb truck doing 45mph uses some juice. A good rule of thumb, is 150amps for 4s 125 for 5s, and 100 for 6s. If you plan to squeeze out the 60+ mph claim on the flux, 2 polyquest 6000 25c 3s packs in series will be the best bet... 2500watts after losses, or 3.3hp...

Ok so I understand this yet here in Australia they are being told that ESC's are blowing as they are running the 20t pinion in a flux and not the 25t for 6s? I mean WTF? By your logic I should go down to a 14-15 pinion to lower the amps, by their logic I'll blow everything up!
What is increasingly frustrating is the lack of response to my direct questions on this matter by email to castle creations, there are more and more savage flux - ESC go boom - videos coming onto You Tube, yet I can't get any clarification on this matter, just a lot of theorising.
