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!
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? :D
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.
See this post for a discount on the Panasonics, they drop to the same price as FT at $17.xx for 2.
Hope this is cool sirius9? I assume so, you posted it openly.
Yes, of course, let’s spread the love just joking
$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.
