Panny NCR18650b 3400 mAh battery, safe for sub ohm?

[wadywad]

I am relatively new to sub ohm vaping, i have a .4 dual microcoil on a king mod.

I know battery chemistry is important, so is amperage and continuous discharge. Looking up the stats of the panny ncr18650b 3400mah batts, i found that they have a max continuous discharge of 6.8amps.

My question is, is that safe for my .4ohm build? or should i continue to use my sony 30amp discharge batts? I basically got these batteries for longer life, thinking they would be ok in my mech mod, but i was told by a more experienced subohmer that i should not.

and what does NCR stand for regarding the battery chemistry?

Using ohms law calculator,
Assuming fully charged battery of 4.2v
0.4 ohm would require 10.5A current draw.

Based on 3.7v, you would need 9.25A

Go for High current draw batteries such as the ever popular discussed AW IMRs,
on the safe side, you should be factor in a safety factor of 80% of the maximum rated Current draw for the battery.

Panny NCR18650B would not be a wise choice for your 0.4ohm setup.

Please do a search in the forums as most of your queries are very often discussed,

Ok, you do the math. Use this Ohm's Law Calculator. Put in 4.2 volts for the voltage. 0.4 ohm for the resistance. Hit calculate. Your 0.4 ohm coil will pull 10.5 amps (current) from your battery, effectively throwing your battery into thermal runaway. Nice explosion you made. Any teeth left?




NCR stands for "Nickel/Cobalt/rechargeable", designating it as a hybrid li-ion rechargeable battery.

FYI, the NCR18650B 3400mAh battery is not a "high drain" battery, which is what everyone should be using with an RBA. When using sub ohms, amp limits are far more important than mAh ratings. This is one of the worst batteries to use for sub-ohm - in fact it is totally inappropriate. For the correct batteries to use in your mods, follow the advice in the following blog:

And the main reason is that it will vent...and vent hard...if the button gets held down by mistake. All it takes is once.

So sub-ohmers can talk about "intermittent" vs "continuous" discharge all they want; you go for max safety and use the continuous figure as the limit.

thanks for all thee info.
