0.5 ohms safety

[3.7volts]

Okay, I've been using an Efest 18650 v1 2000mah 10amps in a fully mechanical mod with a 0.5 ohm coil..
I calculated this in an Ohms Law calculator as follows.

Voltage = 4.2v
Current = 8.4
Resistance = 0.5
Power = 35.28

Question, will my efest handle it with ease? or am I in the risky side of vaping? Don't want to blow my face off..

Thanks ECF!

I personally try to be super crazy safe with sub ohm vaping.
I try to only push my batteries to half of what the claimed draw is.
I am using 20 and 30 amp batteries in my .5-.8ohm setups.
But that's just me. I like to play things safe.

I try for the .08 range to 1.0 ohm just to be safer on my rbas. Dont use efest so dont know. 10 amp on those might be pushing it.

get some better batteries.......the efeset 1600 MAH will be good for those ohms but like stated above i try to stay at half or below the limit of the battery. I only use 24 or 30 AMP batteries no matter if I'm running a .9 ohm or .4 ohm......

Okay, I think 0.7-1 ohm will put me in the safe side.. Thanks guys

Those batteries in particular are not the ones to be pushing it with . . . . . here's a quote

Acceptable performance up to 7A, but they have problems with 10A.
