Thx.
First! (I guess)
Got the cells, started capacity test right now.
Edit:
2036 mAh and 2009 mAh, measured at 0.5 A in my charger.
which tester did you use?
AkkuPower IQ-328+, probably a LiitoKala Engineer Lii-500 derivative.
My tracking has been updated. It now says that it left NY yesterday - 07-25-2016, heading to the destination. Yet, it says that the estimated arrival date is this Saturday - 07-30-2016. How can it take a week to go from New York to North Carolina? Anyway, it is at least past Customs and on its way to me now.
Second?
Just now received 4, put 2 in the BC3100 for testing capacity at 500mA.
Will this Battery be available again ?
My 2 pairs arrived at USPS San Francisco 7/26 at 12:54 am so I’d expect them to be here on Saturday.
Expected restock on 3rd August 2016
otherwise they write sold out usually
Built a MT-G2 into a Ultrafire F13, with two fresh 26350 cells about 3000 lumens at 8 amps.
Nice!, that is what these batteries are about. 
FWIIW, I measured the capacity of 2 of my 4 cells in the BC3100: resp. 2292mAh and 2190mAh.
Are there any readily available lights to buy right now using these cells?
I like this cells!
Added spring bypasses, 9 amperes now, about 3300 lumens, with modded banggood BLF X6 driver. More than my new Convoy L6 with N2 bin.
Btw, modding the UF13 was a pain with my poor equipment …
In my Shadow JM 30 with XHP 70 direct drive
they work and fit well.
Regards Xandre
got my first 2 pairs
each in a 2x26650 box
wrapped in foam together
in black plastic bag
first pair sits in the OPUS BT-C3100 @ 700mA for charge test
My first charges I did with 700 mA. Now I charge with 1000 mA. Is it too much?
I got two readily available lights where I use 26350s and a third is on its way:
Jaxman Z1 XHP50
Shadow JM35 (2cell)
BTU PK26 (soon hopefully)
Ordered one pair of 26350’s on july 7th 2016.
The batteries arrived yesterday, on july 27th 2016.
And went straight from the hands of the mailman into the BT-C3100.
A charge-refresh cycle on 500 mA resulted in 2,256 mAh and 2,210 mAh.
are these cells sufficient for the BTU PK26? I think they are 4A drain. Don’t they need to be more?
