Sony vtc4 safety

[cloudyjosh94]

Hey guys just started sub ohming got 18650 Sony vtc4 in mech mod.
I believe these are only safe for sub ohm.
I have heard a lot of talk of how dangerous sub ohms are how can it
Go wrong I never go below .3 ohms?

VTCs are good for sub and super ohm (above or below 1.0 ohms). The do have a relatively short battery life (mAh rating)
At 0.3 ohms, the VTCs are fine (if they are legitimate and not knock-offs)
The danger of sub ohm vaping rests with the vaper... if you do not know what you are doing, then you can short the battery and cause it to vent. This becomes exponentially easier to do as you go lower and lower with your coil resistance.

I suggest that you click the link in my signature titled "Bad's Awesome Blog"... there are headings in there for battery safety and ohm's law... read and understand that... I also suggest that you stay above 0.75 ohms until you get a better handle on the safety aspects of sub ohm vaping.

Ok I know ohms law and how it works using ohms calculator Sony vtc4 continuous dicharge is 30 amps
Max voltage is 4.25. From that I work out that the minimal resistance is .19 which is 28.3 amp.
So aslong as I take care of my batteries and keep my resistance over say .25 am I safe?

If you understand all of the underlying safety issues and how to mitigate them, then yes. The VTC series of batteries are perfectly fine at 0.25 and above...
The only other thing that you should know is that Sony is no longer making the VTC batteries. They stopped production about 9 months ago... so any new VTCs that you buy have a high chance of being fake batteries (a re-wrapped cheaper battery of unknown amp limitations). The VTCs are now being produced under the name Xtar. I don't know any reputable battery vendors in the UK, but these are the batteries that I am referring to: Xtar 30A

Ok thanks for feedback. The shop I bought them from said they were last ones they will ever get and was worrying about which to get when they die but will look into these now many thanks

No problem, Josh... Stay safe, mate!
