Chart of C ratings vs size
These ratings are general guidelines taken from information on the internet and NOT all from the manufacturers.

1C or less for some Li-FePo4
Assume 1C for generic Li-ion unless otherwise noted
1.5C for ultra/sure/trust/-fire Li-ion
2C for AW ICR (Li-ion)
3C for BDL 10440 IMR (Li-Mn)
5C for BDL 14500 IMR (Li-Mn)
8C for AW 14500 and 16340 IMR (Li-Mn)
10C for AW 18650 IMR (1600mAh) (Li-Mn)
10C for AW Li-FePo4

Max drain rate in amps is C in mAh / 1000 x C rating

Example: an AW IMR Li-Mn 14500 battery has a capacity of 600mAh. The C rating is 8C (it can supply a load of 8 times the capacity).
Therefore the max discharge current in amps is: 600 x 8 over 1000 (600 multiplied by 8 divided by 1000)
= 4800 / 1000
= 4.8 amps

This shows it has enough beef to safely and effectively run an atomizer - which some 14500's don't. In other words it is less likely to go into thermal runaway if there is an internal fault in the battery, is overcharged, and is then used to power a device that draws a relatively high current such as an atomizer; and it will not suffer from excessive voltage drop when powering the atty.

Useful formulas
Amp draw = voltage / resistance

Example: a 5 volt APV is used with a 2.5 ohm atomizer - what current is drawn?
5 / 2.5 = 2
The battery must supply 2 amps.

Power used by atomizer in Watts = volts x amps, or volts x volts / resistance

Example: a 5 volt APV delivers 2 amps to the 2.5 ohm atty - what power is used?
5 x 2 = 10
The atty uses 10 watts
or
5 x 5 / 2.5 = 10 watts

Thanks for all the info. And welcome to the forum!!

Why did you copy & paste this info from the kriti kal mass site?
For the most part it is inaccurate

There is no such thing as an 18650 battery with more than a 30a continuous discharge rate.

I'd trust information from the people that actually design, manufacture and test them using industry standard methods before info from 'internet'.

Seriously.. Among other things, without the headers in the chart, this information is kind of useless.

I get that you may have been trying to help, but really between the potential inaccuracy of this information and the way it's presented.. er.
