I believe in this day of modern battery technology there are few applications when I would choose a protected ICR battery over a safe-chemistry high-drain battery like an IMR or hybrid battery.

IMHO, the top general purpose battery for mod use is either the
Panasonic or Orbtronic NCR18650PF and
NCR18650PD 2900mAh 10 amp batteries. These two batteries have an adequate 10 amp continuous rate for most applications and also have the highest mAh rating of the general purpose mod batteries.

The Panasonic or Orbtronic
NCR18650A 3100mAh and
NCR18650B 3400mAh batteries are hybrid batteries with their chemistry extremely weighted towards the ICR end of Lithium batteries. They are not considered high-drain. They only have a 6.8 amp continuous discharge rate.
I don't recommend using these batteries for regulated mods, mechanical mods using a Kick, or for sub-ohm vaping. These batteries are best suited for low-drain applications such as flashlights or cameras. Pratically speaking, these may be considered ICR batteries IMHO.
If you want the best performance from your regulated mod or mechanical mod using a Kick, you'd do better with the first two Panasonic/Orbtronic batteries listed before.
Rationale: regulated mods use PWM (pulse width modulation) to achieve higher voltage. The "user set voltage" is just the
average voltage, the processor may actually pull twice the amps (up to 9 amps) of the average voltage setting to make the pulse currents required to achieve the user set voltage. The two Panny's in the previous paragraph may not be adequate to do PWM in a regulated mod or a mechanical mod using a Kick. This concept is explained in this link:
Technical - Why high drain batteries?
These batteries will "work" in a regulated mod, but performance may suffer. Why do they work at all? They work when the output is not adjusted to supply high power. They get by running at low power but the full capacity of the battery is never available because of voltage drop due to their higher internal resistance causes them to shut down early. So, if you think you are getting 3400 mAh out of this battery with that rating you would be wrong.
