Does it stack up against the competition when protected? I have a couple of lights that use 2 or 3 cells and don’t like the idea of unprotected cells in those, especially the 3 up. Who makes this Sanyo battery in a protected version? Is that the ones linked at FastTech? I’ll check into em. Thanks for the intel.
Not sure who makes the protection pcbs but the cells are the genuine ur18650fm by Sanyo in the one I linked.
They’re cheap too…
Ok, I only asked!
Ahem…….Sanyo?
Rob, you know what I meant! Sanyo doesn’t put protection circuitry on it, so the obvious question was who “offers” this Sanyo cell with protection circuitry?
Geesh, is this cpf? 
I’m considering these for my Solarforce S2200 with 3 up 18650’s. I’ve been reading that IMR chemistry is safer than even a protected Li-ion, as protection circuits can and do fail. With the price being so low on these Sanyo’s at FT, makes me wonder how reliable they’d be under load and in sets of 3? Had any experience when using multiples? Right now I have Protected AW 2600mAh Black cells in it.
AAALLLLLLL together now….
the……stars at night, are big and bright (clap clap clap clap)…………….
My question was in the interest of determining whether or not the protection circuit used by FastTech was/is of sufficient quality to allow the superior test results of the Sanyo cell to shine through. It may or may not be a known fact that the protection circuit can hinder a cells functionality and reduce it’s efficiency to the point of diminishing returns. So, while the Sanyo cell may actually test out as a fantastic cell does it continue to hold these ratings with the protection circuit as supplied by FastTech? What does the protection circuit limit amperage capability to? What is the cut-off point of overdischarge protection? Is the thermal protection set at a viable level?
Ohhhh, you should have just said………
Well that is not true… Sanyo 2600 can not beat Panasonic NCR18650PD and it is superior battery to Sanyo under high loads of current more than 5A but it even beats Sanyo at lower currents like 2-3A.
Your link Battery test-review 18650 comparator is ok but you have to chose
Sanyo 18650 2600mAh (Red) bv vs EnerPower+ 18650 2900mAh 3C Put on 3A current draw for real results similar to this guy here:
http://www.dampfakkus.de/akkuvergleich.php?akku1=141&akku2=122&akku3=103&akku4=99&akku5=&akku6=&a=3
And thrust me on more than 3A(4-5A) it beats the hell out of old Sanyo 2600
Yes I would also like that your data is true considering the price of both cells but sorry that is impossible.
So Slewfish I guess you will have to order some PanaNCRPD now ? 
I already have 10 sets on order because I also compared wrong cell on Battery test-review 18650 comparator page like you.
P.S. Look at results at 5A of current:

Well, the Samsung INR 20R beats them all, no competition. It's the lowest resistance battery tested by HKJ. Of course it doesn't mean it's the best for all applications, but I found with XM-L2's on copper, resistance is the enemy and the 20R's are the reigning king.
Yes U mentioned that few days ago…
But I can not find it anywhere… Any link to them?
Yes, I know I'm repeating myself on different threads, but I still keep coming across more and more examples. Latest this past weekend was with a mod'ed Shocker. I bought mine here: http://www.ebay.com/itm/HID-Battery-Samsung-20A-18650-20R-INR18650-20R-2000mah-3-6V-Li-ion-Rechargeable-/321080176476?ssPageName=ADME:L:OC:US:3160
I ordered a pair although I don’t like ebay…. But they are not cheap 15$ pair But they will sure come in handy.
Obviously no one of famous sellers dx,kd,ft,is,i-o,ab carries them?
I guess they would be 2$ cheaper at their stores considering ebay fees.
Yes agree - I requestet FT to get them, but all they got was the 20Q's, which are good, but not as good as the 20R's from what I'm actually seeing/measuring. FT has a great price on the 20Q's and was really hoping they'd do the same for the 20R's. At one point, I thought the 20Q's were equivalent, but don't think that's true now.
INR18650-20Q cost 10$ at FT so R model should not be to much priced than they are.
I think you could open thread of interest for Samsung INR18650-20R 2000mah battery… We will sing and FT will get them?
Friends I've done mods for are buying the 20R's - I paid $22.50 for qty 3 from this source, but $20 would get you 4 20Q's from FastTech and expecting the 20R's to be the same price at FT. Dunno if FT really listens much - they are not as responsive as they used to be.
Maybe they will see this thread and listen to you as you are one of the most popular modding expert on planet.
You could get them just open the thread, we will have 100 signatures and pass that to FT and thing solved…
Where does it say amps? The y plane is volt and the x plane is seconds. I don’t even understand this.
But I wouldn’t be surprised to see ncrpd outperform urfm at 5A. My light with highest current draw at the moment is the Shocker at 3.8 amps per battery. Maybe when I start getting to 5 amps+ I’ll start investing in a ncrpd, or 20R
I’ll sign…
Me too!
Oh sorry….
