I couldn't resist it, I ordered one from DX in spite their unbelivable long delivery times Smile

Those looks like 26650 King Kongs (not 18650). Please let me know if you ever can use them on TR-J12. Thanks. They should not work.

They are too short. You need longer (protected) ones.

I would avoid protected, can't you use spacer or longer springs?

Are you gessing that they are or are you sure? I haven't actually tried them yet, they're still charging. But why so negative :P? If three 18650 fits then three 26650 should, they even fit each others chargers...

Bah...just put some solder blobs on them.

Do not try neodymium disc type magnets.  They might short out at the positive end, should you knock the light hard while it is switched on.  It's not supposed to, coz the internal is anodized. But there might be negative contacts at the front and you know Murphy's law always kicks in.   3 x 26650 gives a lot of boom, these are not IMRs.  Be careful when using them HB201 and jurdiciously monitor the voltages.  Do not use for long periods or leave it unattended.

I believe he is going by the manual, which is probably not properly translated. Theoretically, the voltages of 3 x 18650 will be the same as 3 x 26650.

Doh! Negative? Just facts. I know. J12 works with 3x26650 and 3x18650. You just have to find tricks for your King Kong 26650. Smile

Try and share some more information with us then. you post cryptic messages and make us try to decipher what you are going on about.

It's difficult to share. You guys know everything and I am new to flashlights. I am trying to share info. But it is hard!

I leave this case to experts.

Check out mitro's battery tests, upper left hand search field, it's pretty good.  Each king kong can do 10A.  So basically each cell can supply 30 watts of power. 3 of them have a 90W potential.  Even 2 x King Kongs is a piece of cake for the light.

IMRs are inherently safer.  Google LiMn (IMRs) and Lithium Cobalt.  BTW, i mentioned safer, not safe.  Smile   The safest is LiFePO4, but that is 3.2V and pretty much lower in capacity.  Do a youtube search on everything, you can whack LiFePO4 around like crazy, burn it with a 1300C blow torch, and it'd be quite a while before it explodes.  Smile   Correction, it does not even explode.

Safest is just get 3 x 18650 protected high-quality cells like XTAR 2600/3100 or if you can afford it AW/Redilast and be done with it.  Still loads of runtime.

I believe that he's referring to the safer chemistry of the IMR cells.  Magnets shift, a short occurs, and you have a pipe-bomb with at least 1/3 more energy than the one that destroyed a coffee maker, window, and human hand.

EDIT: 2100 beat me to the punch by a few sec.

I know those cells, I have many original a123 3.3v lifepo and others as I am RC car racer Smile But king kongs are new to me, I bought them and their resistance is as imr, capacity higher. Safety...is not that important for me Wink

Safety in RC is a bit different from flashlights. RC you can blow up the bugger with enough smoke as if you lit up a 100 shot fireworks cake and no issue, coz it is outdoors and not in your hand.  But a flashlight is often in your hands, plus it is enclosed tightly plus extremely securely (a good tube of 6061-T6 is tougher than you think).

Nice Smile But high current cells usually don't do this without reason, if they do  at all. Remember I charge all my batterries at home Smile So it is not always outdoors Smile My transmitter is lipo powered, I even use liion cells at home to power up home devices. Killed many cells, they always warn you something is wrong.

Yep, for you since you are in RC, you'd have at least the basic skills and equipment to test and monitor.  Charging, discharging, testing is a side-line hobby by itself for some of us.  Check out old4570/mitro/HKJ's work.   But the true is, I think 98% of us here don't even have a basic DMM or lux meter.

But this and good chargers should be something normal. You see what is wrong with cells every charge if you have at least resistance measure and simple thermometer. Past data you can even collect yourself if your charger can't. If you want to say that one light is 5% stronger, it is hard to see with your eyes, you need a meter.

Any of your cells may. But you usually have to hurt them before Smile Overcharge, over discharge -too low voltage, over discharge with too high current, physically damage.

Yes but I'm using small magnets on the + pole, because these weren't able to connect in series due to they didn't have the + side further out than the cylindrical body of the body. Any precautions?

I don't like idea of objects which can make a shortcircuit inside flashlight, can;t you weld some material on cell plus to make it higher? Of course many people use magnets and it works, but it is not safiest method in my opinion Smile
