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.
Just thought I should bring it up as it was not mentioned in the first 96 post on this thread incase new people are looking to buy some 26650's and resurching. It has been mentioned on some torch threads the TR-J12 is the only one I can think of right now.
Well the Sanyos can be used in series in a battery carrier. :)
Anyway, just add a blob of solder.
Definitely, which is how I use them at the moment.
Yeah great batteries if you have to add solder to them so you can use them, im surprised the battery reviewer did not pick that up 
. Im going to solder small light duty driver springs to the positive end and maybe even remove a driver spring on one of my torches. To recharge them im going to use a magnet on the negitive side and a aligator clip for the positive side. Also there is a bit of diffrence with the cells IR and mAh if any one has noticed yet when testing multible cells.
I soldered some amount of solder material at the positive end, not little, rather more, then just some seconds with dremel on them to clean and they work on trj12 without problem. Even a123 you can use there after such mods.
It's funny I got some cell samples recently that look just like that. Gold wrapper 26650. However they say ICR instead of INR. There are definitely 4500mAH+ 26650's out there.
Keep in mind though that your hobby charger is probably not very accurate. Infact my hobby chargers charge mAh readings is off by literally 10%! So you may want to verify the accuracy of your hobby charger. 4500mAH is possible for ICR, but not likely for INR.
For the record fresh MNKE IMR 4000mAh cells (while they were still being made) did about 4200mAh!
I think my Hype-RC X-treme Charger X8 overcharged my ICR26650E battery.
Here is the battery:
And here is what the charger displayed after charging:
Here is the charging graph:
I monitored the charging at my computer and wasn't concerned because the charger monitor programm showed 4.2v as you can see in the picture above. After seeing 4.35v at the actual charger display I tested the cell with my DMM and got an reading of 4.39v.
Any advice how to handle that cell?

Ive been testing a trustfire protected 26650 5000 mAh battery.
1 amp discharge.
4523 mAh (matched the king kong's)
3 amp discharge.
4313 mAh (better then the king kong's)
5 amp discharge.
4533 mAh with the PCB removed (better then the king kong's)

I'm glad I'm not your charger Benkie. You have given it a real flogging lately. Thanks for all your work.
Between the battery testing, charging my xbox controller batteries, digital camera batteries, my EDC torch batteries my charger has been on every day for over a week now, it has spent most of its life like that, its why i recommend the icharger 106B+ and my P350 power supply. Now I'm running test,s on some nimh's then cycling my RC batteries that have not been used in a while so no rest for my charger just yet.
Like a complete muppet I left my Poppas 878 XML ftt light on before going to work. It’s kind of my replacement bedroom light until I get round to fixing my light switch. Came back 5 hours later and the thing was still running on high with the King Kong, although it was very pale and flickering. I’ve got it on the charger now, any advice? Think I can still use this sucker?
Should have checked voltage first.. I wouldnt charge it unattended.
Thanks the advice, I’m keeping a close eye on it. Unfortunately I don’t have any equipment to check the voltage. Interesting to see what happens…
It's good advice. Really shouldn't be using an unprotected cell without checking voltage. 26650 packs a lot of power.
I know, I need to get round to purchasing some hardware to measure voltage of these suckers, might as well as it seems I’m newly smitten by this flashaholics disease. I doubt I’ll find anything like this from where I’m living at the moment, I’m pretty remote in a small city in the central Highlands.
Any advise on where I can order any equipment?
Any hardware store should sell DMMs...
