Feigao 8XL/9XL Current Requirements

[What's_nitro?]

Relative to my EDF F103GT project I need to know the current requirements of both motors when running on 4s LiPo. Full-throttle continuous current is my main concern, but peak current would help as well. I'm trying to find a pack which will both fit comfortably in the vehicle and also be able to power the setup without issue. I have a 28x155x55mm maximum area that I can use for the pack.

I was thinking about these. Tanic Packs 4s 3650mAH 20-25/40C Would 70A continuous be enough?
