Fenix and Nitecore batteries

[JSRP]

Anyone know anything about these two batteries?

Fenix 3400Mah 18650:

NiteCore 3400Mah 18650:

I was wondering if these could be a good replacement for my Sony VTC5's when I'm using something with a higher resistance such as my kayfun (1.2-1.3 Ohm) on a mech.
They are both protected however (so not IMR) and don't mention an Amp Limit / C-Rating. Any info would be great, thanks.

I would not try to use those batteries for vaping.

None of the important specifications are listed (such as max amperage, chemistry type etc.) and protection circuitry is mostly used on ICR chemistry batteries. As you have noted.

The Sony US18650VTC5 batteries you have will work just fine in less demanding situations. They work great actually.

A lesser battery may show more voltage sag, quicker than the Sony anyway.

mAh ratings are based on a batteries entire discharge. When used on a mechanical, most of the time a battery's voltage will drop off and result in a less satisfying vape long before it reaches its max discharge.

I actually suspect those batteries are rewrapped Panasonic NCR18650B protected batteries but who can tell?

Your Sony vtc's will work just great. I would stick with those.

I had a suspicion they were re-branded NCR18650B as they have that written on the side and the only place I have ever seen that nomenclature before was on the Panasonic Cells I used to use in my itaste SVD (7amp limit ICR).

Currently with my mech i'm using 2-3 Sony VTC5's a day and have the need for something larger. I currently have a Protovapor XPV DNA30 on the way with a Sony VTC5 and am hoping that it will last longer as it is regulated.

Considering getting a 26650 mech as those 26650 cells iv'e seen are rated at 4000Mah+

A regulated device does allow you to use more of a battery's capacity. With a mech, as the voltage falls off, so does your vape. Boost circuitry in a regulated mod gives you that "first is a good as the last" experience.

In my personal experience using my mech mods, when my batteries are at 3.8v or so I notice a drop off in vapor. At 3.6 it's over for vapor production.
That same battery would be good for many more hours in my regulated device. "the first is as good as the last" right on down to the cut off at 3.2v.
