Suitable batteries.

[NickTs]

Hello all,

came by to find useful info on vaping related things and I was wondering about the suitability of my batteries. Currently I am using this mod

iStick TC60W | Wide Range of Batteries @ Eleafworld

and the battery is

ThruNite 18650 Battery 3400mAh*2

Is this battery suitable for my 18-22 Watts preferred vaping and for my mod?

I'm not familiar with that particular rewrapper but you'll find most everything you need to know here Mooch's blog | E-Cigarette Forum

@Mooch may be able to give you more insight into it.

I've never heard of that battery though if it is really 3400mAh then it is going to have a 5 to 10 amp CDR at best. Quite possibly a lot less than that. As long as these assumptions are right then you should be ok(ish) as long as you don't exceed 20 watts. Good batteries are easily available and cheap if you know what to look for. Avoid Amazon and Ebay as they are rife with over-priced, poor performance and fake batteries.

You've come to the right place to smart yourself up as we have a resident battery expert called Mooch, I strongly recommend you have a read of his blogs.

There's no 18650 battery greater than 3000mAh that is recommended for vaping, so I would look elsewhere. I've never heard of that one either. It's either an inflated number or a low current battery.

There are a couple that Mooch has tested

Sanyo NCR18650GA 10A 3300mAh 18650 Bench Retest Results...a great 12A battery
Pegasus Vapor Academy Type A 10A 18650 Bench Test Results...a very good 10A battery, probably MJ1

Yeah, low watts should be fine with 2 if 7A CDR is correct. As long as your not to far beyond the CDR/MVA you'll feel the battery/mod get very hot long before it hits venting temperatures.

Considering the thrunite t3400 is a rewrapped Panasonic NCR18650B with no sub model mentioned it could be anything between 3.6a CDR to 7.2a CDR.
Because of the higher internal resistance of the 3400mah cell you'll actually get more run time from a quality name brand 3000mah 20a CDR cell and give yourself the ability to use the full power range of your istick 60 safely.

Protected batteries...NOT Panasonic NCR18650B, which are unprotected.

Forget them. Sounds not very trustable...i woudn't even touch.

Btw: They sure are not suitable for the IStick 60W.

I'm almost certain those batteries are designed for use in LED flashlights. ThruNite is a flashlight manufacturer if I'm not mistaken.

 

[Joergl100]

Yes: ThruNite LED Flashlight--Guiding you through the night!

get yourself a night LG HD2 brown battery, take the guess work out, and keep safety in mind.

I made the mistake of using batteries that weren't up to par when I first started. I'm certain it was a re-wrap designed for flashlights. Ecogear FX 3000MAH/40a (pfft) I dropped them in a Sigelei TC 150, and they vaped ok at 50w. I went up to 75w and the board temperature went up a few degrees, so I thought "what the hey, let's take it up to 100w!" Vaped ok, then got a message saying atomizer short, then the screen flickered and I got a tasty surprise of the scent of burnt electronics mixed in with vape. Got the batteries out faster than you could say "holy smokes, batman!" and noticed wisps of magic smoke emanting from behind the battery sled. Upon disassembly, I noticed what looked like a regulator completely charred into what looked like coal. It's not worth it! Do NOT skimp on batteries!

 

[Joergl100]

Ecogear FX 3000MAH/40a (pfft)...pfft meets it exactly!

HG2 is brown...HD2C is purple and pretty heavy duty...with small capacity: LG ICR 18650-HD2C - 2000mAh 3,6V - 3,7V (25A Konstant) Lithium Akku Lithium-Ionen Akkus 18650 LG

I meant to type OR browns lol... I blame the hubby making me move from the garage desk mid-reply...

True, I should have said 20A 18650, which is generally, at least, what's needed with modern gear. Unless you stick to very low wattage.

 

[Cheallaigh]

lol during the day, I'm generally on the garage comp... today with fresh snow it's a musical chairs day as everyone and their sled dog wants snowtires right this second.

@NickTs
There are only a few companies in the world that have sufficient manufacturing clout to actually produce 168650 batteries, namely Sony Panasonic LG and Sanyo. These batteries have known and trusted performance with published specifications.

Then there are companies like Thrunite, Efest and many more who take the cast-offs from the these big players, place a nice new shiny wrap on them, write some highly exaggerated specs on the side and then sell them for a big mark up. They are the equivalent of a dodgy second hand car salesman.

The best advice I can give you is to completely avoid re-wraps, and buy your Sony LG or Panasonic branded cells from reputable vendors. If you are unsure if which one suits your needs just ask, and read through the material I suggested and educate yourself.

Correct.

Yep, think I am gonna go for the LG HG2 18650 35A 3000mAh. Think this is the brown one, right?
