By PM you told me you wanted to get the 7XL, which is a good choice for 4S lipo. with proper lipo's i meant, get something that is capable of delivering the current, without thermalling it's life earlier than expected.

A good choice would be to get the maxamps 4000's on 4S2P configuration. That way you will have got plenty power and runtime on your side.

if you can afford it, a Neu 1512 or 1515 would be a wise choice too. I also heard a lot of people running their mamba-maxx on 4S lipo, with great succes!! They do use an external Ubec and take the red wire from their receiver/speedo plug to prevent the speedo's BEC to interfere with the external Ubec.
