Yup. Better PCB has lower internal resistance, and therefore less voltage drop.

I guess the clear PVC concept pays off.

just ordered myself a pair of panasonic 18650 just like in the review but with 3100 mAH.

little bit regret however the price spread between the two brands can reach $5 for the same capacity.

mind to elaborate with your post of clear PVC pays off?

It's not branded, but you can see the Panasonic original battery wrap underneath. No matter what protection circuit is used, the cell will be bought in masses for being Panasonic.

I have put in a request a few days ago for FastTech to start carrying the keeppowers 3400mAh, they told me this morning “we will update you when it’s here”
_
Others on here may wish to do the same, the more requests maybe the better chance they actually will carry them soon, but it does sound like from their reply they will carry them. I gave them a link to a competitor for the product that shows the price and graphs showing how good the batteries actually are.

I think FT will gives us a better price and a much quicker turn-around time for USA customers.

The battery inside is, of course, the same. The Keeppower protection circuit has slightly less voltage drop and considerable higher current limit (If this is good or bad can be discussed).

The Keeppower is 1 to 1.5 mm shorter, this can be very significant!

1st option is protected.

If you have to ask, it’s the one you should buy.

I looked at the heading, it does only say protected for one of them.

But you are right, both batteries has photos that shows a strip and a black extension at the bottom.

Except the photo with batteries in a box, there they do not have the black extension.

That is obvious a mistake, that a couple of sites made when the battery was new.

cell3, 70.24mm × ø18.42mm

cell4, 70.21mm × ø18.47mm

They fit well in all of my EagleTac lights (SX25L3, TX25C2, T20C2, D25LC2, D25A) but not in my Nitcore TM15 **ck. In € currency i paid a total of 20.76€ for these 4 cells altogether. ~5€ per cell. hmm. still too expensive? Big Smile

Just a word of warning with these. they are long and I have found in a couple of my lights if I tighten the tail cap too much it dents the bottom of these cells. See image:

They are sold out now for quite a while. Does anybody know how long Fasttech usually takes to restock such items? It’s the first time I see them sold out on that site.

If FT is out of Panasonic 3400’s, BG still has them. Couple of bucks dearer though. Look exactly the same, brown stripe for the protection strip. Black bottom, silver plates at the ends, white ring around + end.

http://www.banggood.com/2PCS-NCR-18650B-3_7V-3400mAh-Protected-Rechargeable-Lithium-Battery-p-90990.html

See this post for a discount on the Panasonics, they drop to the same price as FT at $17.xx for 2.

Yes, of course, let’s spread the love Big Smile just joking Silly
$17.69 is OK-*ish* price, they were cheaper not so long ago but now, a lot of suppliers are out of stock or sold out on this particular cell, not sure whats the story with that, anyways, if for some reason you need this particular cell $17.69 is lowest price for now, otherwise I would go with much cheaper NCR18650A from DX.

So the Fasttech sold out status is nothing permanent as far as you guys know? I don’t need them fast. Just for the good price.

No idea how long it will last. It might be permanent, might be temporary. There was chit chat regarding these not being available from Panasonic anymore. But that seems unlikely. Its hard to say if tye would get them back or not, but likely they will sooner or later. Most of these guys seem to show stuff they havent stocked in quite awhile, Im not sure they ever delete any line from the website lol.

But the Banggood deal is as good. Just PM sirius up a couple of posts above, and ask him for the discount code. Enter it at BG when you add to cart, and you will get them for under $18, which AFAIK, was much the same as the FT price.
