If I were to use a 1.8 ohm coil on a mech the max amp draw is 2.33 when battery is fully charged at 4.2 ohms. If I am looking for an extended battery life between charges can I use a ___fire brand to get a longer battery life. I would not go any lower then that on ohms.. If not, what's a large mah 18650 battery or 18490/18500?

The Panasonic ncr18650pf is good. 10 amp, 2900 mah. I believe the 18650b 3400 mah can take 6.8 amps. As for protected batteries, they are not high drain and therefore unsuitable for mechs. Also, safer chemistry is always to prefer over protected icr batteries. And, protected batteries are longer and will therefore not fit most mechs. And finally, ****fires overstate their capacity so they'll most likely last for a shorter time than the Sonys.

With this one you won't need a fuse, it has a built in protection circuit: Panasonic NCR18650B 3400mAh Protected Button Top - Batteries

Just for added info, these Panasonic batts are pretty darn awesome. After a day of use where my AWs may read 3.7, these read 4.0. Not sure how long they last because I usually swap them out daily between 2 of them. I may only need to swap every other day with these so I'm going to try that. I've only had them for a week. BTW, they are longer like one poster said and do not fit in my Provari without a very small gap by the cap but I've inserted an o ring to take up that space so moisture wouldn't get in. It rocks so far.

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.
