What mod, what rda, what battery, do you have a way to measure resistance, do you have a way to check for shorts?
Everything that kaezziel just said plus you need to know and understand ohms law and how it relates to vaping.

JUST an FYI - your batteries are not 35A (even though that is what they are labeled). They are 20A continuous. This link is from Baditude (our resident battery/safety expert): Purple Efest Batteries not as Advertised.
If you are new to mech mods and rebuildables become familiar with ohms law, amp draw so you do not exceed the continuous Amps (with headroom for safety) of your battery. I use 25% for safety (i.e. with a 20A battery I would consider to be a 15A battery and respect that limit when I build). Here's another blog post by Baditude: Ohm's Law for Dummies (Vapers)
Use the link equilibrum provided to get the resistance where you want it for your coil.

As Susan said, that's a 20A battery... 35A is the pulse limit (and not a recommended range to operate in).
A 10/9 wrap will put you right at 1 ohm... that's 10 wraps when viewed from the top, 9 when viewed from the bottom.

No problem... at 1 ohm, you'll still be fine with the Efest.
Just be sure that when you plug your resistance into the Ohm's Law calculator on Steam Engine that you use 4.2v as the voltage.
4.2v is the voltage of a freshly charged battery and will give you your highest amp draw. Aside from a short, that'll be the most dangerous time for firing a low res build.
Also, make sure to check your battery voltage regularly during usage. Once your battery drops down to around 3.5 to 3.6 volts, put it on the charger... you do not want to over discharge the battery.

Any time, Will... if you have any other questions, we're here for you. Even send me a PM if ya need to... sometimes I miss stuff in the boards. 
Check this out this is what I have been using.

Download Vapor's toolbox if you have an android. It is the most helpful app I've got.
This site is helpful, too. It let's you see the coil Coil Toy - Online calculator for e-cigarette resistance coil building
