What is the ohm of your build? How many amps is it drawing? Is this your battery?

Steam Engine says his build should be around 0.52 Ohms if it's a dual coil (parallel) setup, or 1.04 Ohms if a single coil. More wraps increases the resistance of your coils. At that resistance, with a fully charged battery, you're drawing approximately 8.08A for the dual and 4.04A for the single. I cannot remember the exact specifications of your battery, hopefully someone else will dig this thread up and report them.
Larger diameter coils also increase the resistance just like more wraps does because you are using more wire.
Please check out this useful tool OP: Steam Engine | free vaping calculators
Disclaimer: This is not to be used in place of an ohm meter, as it cannot detect shorts or any other defects.
OP, whenever asking about a battery and a build, always post your build resistance. If you do not have an ohm meter, please stop what you are doing and buy one immediately.

As Susan noted, what is your tested resistance of this particular build.
Charts and calculators are great at the front end. However, if you have no means of verifying the actual resistance, you may have a potential issue(s) in hand.
Good for ya on moving forward and making coils. However, you need to be much more prepared when stepping into this realm of vaping.
Get yourself and ohm reader, multimeter, and in-line voltage meter.

Idk about efest batteries but I think the sony vtc4-5 are pretty much the best very debatable but from what I've seen they're atleast in the top 5 an te tobh can handle whatever build you want just remember to be safe and not melt or explode anything
Efest 3400mAh battery specs from Efest's website:
Flat Top Efest 18650 3400mAh 3.7V Li-ion Battery （Non-protected)
Specification:
1. Nominal Capacity 3400mAh
2. Minimum Capacity 3400mAh
3. Charging Voltage 4.2 ±0.05 V
4. Nominal Voltage 3.6V
5. Charging Method CC-CV (constant voltage with limited current)
6. Internal resistance: <50mΩ
7. Lifetime: Charge and discharge more than 1000 times
8. Max. Charge Current 3400mA
9. Max. Discharge Current 5C
10. Discharge Cut-off Voltage 3.0V
11. Cell Weight: 50g
12.Cell Dimension:
Height : 60.37mm max
Diameter : 18.25mm max
13. Operating Temperature Charge : 0 to 45°C
14. Discharge temperature: -20°C ~ +60°C;
15. Charge time: standard 3 hrs, fast 2.5 hrs;
Made in Japan.
This means that this battery has a Max Continuous Discharge Rate of 17Amps
5C X 3400mA = 5 X 3.4A = 17A
ETA: Keep in mind that Efest notoriously over-advertises their batteries' specifications... if they say 17A Max Discharge, I would probably consider it to be between 10 and 15 in reality...

If the batteries the OP is using are the ones in the picture I posted then they are NOT SAFE BATTERIES. They are Protected ICR (Li-Ion) battery. Here is what Baditude had to say about these batteries:
They have both a protected and an unprotected 3400mAh 18650... I don't know which one OP has, but as Susan said, the Protected ICR batteries are NOT recommended for use in ANY vape mod! 
8tone8... is the battery that you have a button top or a flat top?

Can anyone recommend me a safe build for tobh atty with 26gauge kanthal? while I get my hands on the ohm meter & a multimeter?thanks [emoji4]
And I'm getting a panasonic high drain battery too,are they any good?

If your batteries are button tops, then they are the protected ICR version of the 3400mAh batteries, and those batteries are not safe for vaping...
That being said, I am not comfortable giving any advice on how to build a safe build with 26g wire considering that you have no means of measuring the resistance.
My recommendation is this:
Get rid of those batteries and replace them with a more suitable battery. Recommend Sony VTC4 or VTC5
Get an ohm meter/volt meter
Do some research here on how to build safely
Do a LOT of research on battery safety
Put your mech mod back in a drawer and use a regulated mod until you have completed the above steps.
Above all, be safe!!

Before you have a way to measure your resistance there is no safe build. Without measuring you'll not know if you have a short. Also, icr batteries, protected or not, are generally considered unsafe for vaping.
