2nd piece of KK 26650 i got 4533mAh, 1A, discharged to 2.60V set on IMAX B6 (UT-58E measured 2.826V, and i tested this 4X by charging a bit and discharging again to test the exact termination voltage, taking good care of contact resistance).
links to buy the king kong and the MNKE ?
the king kong are imr li-mn safe chemistry? I want only li-mn safe chemistry
Get the MKNE then. That is Li Mn. KK can get from cnqualitygoods.com (slightly cheaper overall due to cheaper shipping and 40 cents less for the cell) and int-outdoor.com, MKNE only from int-outdoor but then you need to pay shipping.
King Kong http://www.intl-outdoor.com/kingkong-26650-4000mah-liion-battery-p-136.html
MNKE http://www.intl-outdoor.com/mnke-26650-4000mah-liion-battery-p-223.html
If you buy 3 you pay no shipping.
i like the the KK and the MNKE but i think ill get a few MNKE's when they are back in stock
Moviles, I think the cheapest MNKE are these ones:
http://www.goodluckbuy.com/imr-26650-lithium-3-7v-4000mah-rechargable-battery.html
Out of stock from goodluckbuy too. BTW, search CPF. There are cheap-ass copies of MNKEs.
Ups, I didn't notice they were out of stock.
The MNKE IMR-26650 are available in 4 capacities according to the manufacurer. 3200mAh, 3500mAh, 3800mAh and 4000mAh.
They have been sold for a long time, but not even the US dealers mentioned that, some US bought cells were tested to have only 3500mAh.
Those form goodlucky buy can be any of them since they have no capacity printed.
I think they manufacturing process gave random results and only later in their production they started to select them.
Those copies are actually blue.
I thought they were all the same, mines have exactly the same label, I bought them about a year ago from Taobao.
The same label with what?
With the goodluclybuy ones, without capacity printed on them.
You can see that the ones on Intl-outdoor have the capacity printed.
They were release randomly initially by MNKE, so you may have a 3500 one or 4000 one for those unprinted, depends.
Yeah I get you, but I did not know there were different batches till now, thanks for it, as now I know what to buy if I buy more in the future.
Just some examples:

http://www.mymnke.com/en/index.php/Product/show/id/22
http://www.mymnke.com/en/index.php/Product/show/id/4
http://www.mymnke.com/en/index.php/Product/show/id/3
Initially the capacity wasn't printed and all kinds of cells were shipped probably. But even so probably most of the early ones were 4000mAh
The 4000's did well with the 30 amp discharge and any thing from 0.8 amp to 20 amp is nice and closely grouped. They would do well in RC but might not be cost effective
Does anyone know the exact chemistry of these KingKong cells? I know as mentioned above, they aren't IMR's but what are they then that it can handle such high current draw?
TIA!,
Tim
While these batteries do well for mAh and high draw IMO they are crap if you try and use them in series with out adding solder to them and they will not work in some lights due to the fact the positive button sit's just below the battery outer edge i wish i new that before a brought some.
That's how it is with industrial cells.It's not special with the King Kongs, same problem with the Sanyo UR18650FM, can't get a light to work. King Kong even made the cathode contact higher to compensate for the thickness of the PVC. I have the Sanyo UR16650ZT, those are impossible to be used in series.
