Mamba Monster Combo 2200KV or MM ESC+Neu; why?

[Riko]

but bottom line the CC motor isn't a bad motor?

another question:
I found this on Tower Hobbies http://www3.towerhobbies.com/cgi-bin...&I=LXYJJ5&P=ML


the brushless system is sold seperate from the E-revo and all seems already soldered, so you would only have to install it to your rc.
Basically it is the same as the Mamba Monster combo.

But you will need 2 lipo batteries with those included battery cables.
If I would like to run 1 5s lipo (18.5V) with about 5000 mAh; how would that translate in 2 lipo's?
I suppose you don't have to plug in 2 5S lipo's of 5000 mAh, so wich 2 lipos would you need to have the same result as that 1 5S lipo with 5000mAh?
