Panasonic NCR18650B - I got this right?

[xxJollyRogerxx]

I have a couple of these batteries already that I use in my eVic. Work great no problems etc but of course as things progress in my vape learning curve I am now looking at mech mods cuz I like to play with stuff and just know things in general. And some of them look very cool! I would like to get a mech but not buy all new batteries, etc ... well yet any way. Just something to get started with.

So I looked around and found that this battery is reported as having Max Amp rating of 6.8 amps with a 12 amp pulse. So using ohms law the "safe zone" for a coil for this battery would be .7 ohms. This would be lowest that I could / should go with this battery as not to stress it. It appears that I could go a bit lower but that begins to creep over the safe areas on both amps and voltage. @ .8 ohms I should be well within the "green zone" and not really worry about battery stress at all.


Is this all correctly assumed?

I wouldn't go sub ohm with those batteries, or use them at all in a mech actually. They aren't safe chemistry, which means that they're really dangerous if they go into thermal overrun. Not being high discharge batteries they also have a high internal resistance which means that you'll have problems with voltage drop and probably battery life (even though the mAh rating would suggest otherwise). Get some high discharge safe chemistry batteries, e.g. Sony vtc4 or vtc5, purple efest 35a (actually 20 amps)/LG he2.

Agree. Not mech batteries.

Safe in an evic due to the evic chip's amp limits and built in protections.

Get a high drain battery with at least a 10 amp rating.

Thanks for the feedback and suggestions!

The Panasonic/Orbronic (Orbtronic uses Panasonic cells in their batteries) NCR18650A 3100mah and NCR18650B 3400mah batteries are IMR/hybrid batteries with their chemistry weighted so heavy to ICR that they might as well be considered ICR. They are not high drain batteries. They are safe chemistry batteries due to Nickle and Manganese in their chemistry. They only have a 6.8 amp continuous discharge rate.

These batteries are minimally acceptable for use in a mod using standard resistance factory-made coils. I would not use these for sub-ohming -- sub-ohm RBA's require a high-drain battery, which these are not. They were primarily designed for low drain applications such as flashlights and cameras, not e-cigs.

You my friend are the battery guru but I could use those Sonys in the eVic correct? Just not the other way around

I personally would not use those batteries in a regulated mod either. Not enough amps and not a high drain battery. The regulated mods need over 9 amps to function optimally for the pulse width modulation circuitry of the variable voltage processor.

Why High Drain Batteries?

As I said earlier, those batteries were designed for flashlights, not personal vaporizers. They won't harm your Evic, it just won't be able to function optimally, especially if you enjoy higher voltages/wattages with the Evic.

Not picking nits as i agree on your view of the ncr18650b battery.

The eVic is current limited @ 3amps. The ncr18650b would be maxed out but not exceed its max current at lower voltages used in an eVic. It is the one device that the ncr18650b works in.

The ncr18650b does not do well in a15w max regulated mod in my personal experience.

With so many better batteries out there, the ncr18650b's I bought when they were all the rage are now my go to flashlight and power bank batteries. They are amazing flashlight batteries BTW. Best I have for that application!
