The simple answer is probably not, but the more complicated answer is maybe?
I don't have any of the 35a efests, but I've heard they are actually only rated at 20a for continuous discharge. With the build you have, your running close to 17 amps, which should be ok. I never take my batteries that close to the limit, but I still think you most likely will not push your battery to the point of venting.
If you do vent, hopefully the paps has good vent holes (never used that either).
With all that said, there's always a risk of getting a short or dropping your mod the wrong way or something else going terribly wrong. Just make sure to measure your resistance, keep your mod clean and remove the battery immediately if it gets unusually hot.
Have fun!
