would these batteries be good

[potter3]

I am going to be ordering a mechanical mod from ft and I was wondering if these batteries would work thanks for all the help

Panasonic NCR18650B Protected Rechargeable 3400mAh 3.7V 18650 Lithium batteries

if these are not what I need can you all point me in the right direction thanks again for all the help in advance

Those should work fine for everything but extreme, sub-ohm uses.

Lots of great info here

I agree with 440BB. They only have a 8 amp capacity so not ideal for sub-ohm vaping, or for a regulated mod. But for ordinary juice delivery attachments on a mechanical mod this should be a good battery with extremely long time between charges.

I might point out that battery is not protected unless the description specifically says so (two varieties are made; protected and not). Mechanical mods have no protection. I recommend a Vape Safe Mod Fuse.

If there's a possibility of you getting an RBA/RDA in the next several months, you'd be better off getting one of these batteries, because they have the continuous discharge rating of at least 10 amps:

AW IMR
18650 2000mah 10Amp CDR
18650 1600mah 24A

Samsung hybrid (LiNiCoMnP)
INR18650-20R 2000mah 22A

MNKE IMR
IMR18650 1500mah 20A

Panasonic ​or Orbtronic hybrid
CGR18650CH (IMR/Li Ion hybrid) 2250mAh 10A
NCR18650PD (high drain-high capacity) 2900mAh 10A

Sony IMR
us18650v3 IMR 2250mAh 10A

EFEST IMR
18650 2000mah 10A
​

Battery Basics for Mods: IMR or Protected?

EDIT: I misread your post. I see now that you said they are the protected model. Good to go.

what do you mean by extreme sub ohms like how low cause I am planning on getting a rba

 

[potter3]

would these be better to get

I'm not "flaming" you, but I would suggest that you research basic electricity, Ohms Law and battery chemistry/safety before you start working with an RBA. Going below 1 ohm starts pushing current and power way up and can get a little dangerous. It's important to understand what is actually going on, just to make sure you stay in the safe areas. If you don't already have one, get a multimeter and learn how to use that as well, it can save a lot of head scratching when things don't work as expected and keeping things working as expected.

I'm still trying to ascertain the exact chemistry in the Panasonic NCR18650B batteries. One reputable source says that they are IMR. Another here says they are ICR. I have a pair of these without protection, but I hesitate to use them and instead use the CGR/CH and AW IMR 18650B's. That is, until I can determine for sure what kind of chemical goo is in the NCR.

Due to their nominal 3400mAh ratings, and knowing that you can get more capacity with ICR than with IMR, I suspect that the NCR's could be ICR batteries.

Edit: Rereading your post, you should probably look for a known IMR or hybrid with its own protection circuit. If you use an unprotected cell, you will need to add a vape safe fuse, per Baditude's recommendation.

I know. It was Greek to me, too.

 

[awsum140]

I think the terms "protected" and "unprotected" for batteries is a little mis-leading. Every lithium battery, even "unprotected" from what I have seen and read, has some form of "protection" built into it. All of them have a pressure relief system to allow venting and prevent catastrophic failure in the event of overheating. That is true for IMR and ICR batteries, at least I would bet on ICR having it, as well. IMR, in particular, has had its chemistry engineered to mitigate thermal runaway, which is another type of "protection".

A "protected" battery has an internal electronic circuit in addition to the pressure relief system to limit current and, perhaps, temperature as well. It's the interaction of those internal protection circuits with the protections built into an APV that can make a "protected" battery not work in a VV/VW APV. They limit the current or heat of the battery below the levels that the device requires to operate.

Here's a pic of a disassembled NCR18650B that comes with a protection circuit on a PCB.

While it's true that even today's ICR batteries have better chemistry than the cells that were originally termed "Lithium Ion" batteries, the Lithium Cobalt chemistry is still quite dangerous if the battery is abused or used improperly. When it goes into thermal runaway, the chemical compounds in the ICR are more prone to cause an explosion because of the rapid oxidation of the chemicals.

The IMR cells use Lithium Manganese chemistry. The chemical compounds are no less susceptible to thermal runaway events, but because of the chemistry, the oxidation during the event doesn't take place as quickly and the battery will vent rather than explode.

In the picture above, you can see a yellow strip of plastic laying next to the battery. This is how to tell a protected NCR from an unprotected NCR. The protected version has the stripe and the unprotected version does not.

RTD Vapors sells protected NCR's, but does not sell the unprotected versions of the NCR18650B or NCR18650A.

 

[440BB]

If you're planning on going below 1.5 ohms with an RBA, then I'd suggest going with high drain IMR batteries instead of this one. I'm happy with AW IMR batteries, but there are a variety of high drain choices. High drain and safe chemistry are what to look for in that case, not protection circuits. they may have a lower mah rating, but can handle the stress lower risistance builds place on a battery.

It's very important that you have a way of checking resistance on RBA builds before putting them on your new mechanical mod. A short can kill any type of battery, and put you at risk too.

ok so I am confused these would be fine as long as there protected right here is the link to where I am ordering from so pls more help

The Panasonic NCR18650PD will be fine, depending upon the application that you will be using them for, which I've not seen that you have said so far. These are a hybrid chemistry that are high drain and extended capacity.

I'm don't know the chemistry of the Panasonic NCR18650 Protected to make a comment on them other than I suspect they are not high drain and therefore not recommended for RBA use.

If you ever plan to use the Panasonic NCR18650PD in an RBA/RDA they will have the high drain ability required for coils over 0.5 ohm. With coils < 0.5 ohm, their 10 amp limit will not be adequate for your needs.

If you ever use coils < 0.5 ohm, you'll need either of the following batteries, because they can handle the amps required in that application:

AW IMR
18650 1600mah 24A

Samsung hybrid (LiNiCoMnP)
INR18650-20R 2000mah 22A

MNKE IMR
IMR18650 1500mah 20A​

Thank you Baditude I don't ever plan on going that low it scares me a lil at the moment I plan 0.9 maybe .08 but at first I am going to try to stay around 1.0 ohm so either of those batteries will work for that and I am sorry for asking so many questions I just want to get the best experience that I can

 

[awsum140]

A comment regarding Fastech. They are a good source, but right now shipments from China are being slowed down dramatically by Chinese Customs looking for lithium batteries in shipments. They are "scanning" everything which slows everything down tremendously.

 

[potter3]

so what does that mean if there is a lithium battery in the package
