warrior 9918 esc - Lipo questions

[The Dane]

I have finished my brushless savage x project and I am running 12 cells at the moment. The weight of these packs are too much. Which lipo batteri would be best for bashing around and how much can the warrior 9918 esc handle. The motor is a feigao 8 XL motor.

I have a charges which can handle 14 cells Nicd or Nihm cells and 1-5 lipo cells.

Would a 14.8 volt Lipo batteri with 5000 Mah be too much ??

I will post some pictures of the savage soon. Motor mount is home made.

have a nice day
