Olight IMR 16340 Too Easy to Short? ...

[jayflash]

... And dangerous? Having the + & - terminals a millimeter apart increases the possibility of a lot of current available to quickly over-heat something conductive. Am I mistaken? Unless I overlooked it, "protected" isn't printed on the cells and I did measured a "flash amp" current of 11A on their 5C & 14A on the 10C cells. More may have been available but it was a very quick test.

Maybe my search effort was insufficient but I didn't find any threads about this. It's quite possible I overlooked the obvious as my wife, often, painfully, points that out.

Much has been said about LiIon safety, on the CPF, and my post about short-circuit testing had me wondering about the Olight cells that I just purchased. Are these custom-made and are there other brands with similar termination? I avoid carrying any batteries in a pocket with any metal and hope I never forget to do that.

I try and stay away from freaky proprietary cells and I'm an Olight fan, same with on board USB charging and even rechargeable lights.

I'm old school.

Yes custom "proprietary" cells to work with the now never ending proprietary Olight charging systems they seem to want to bring to market. I have a whole bunch of edc Olights but it looks like no more Olights for me. JMO I don't think this is a good road for them to go down. And no I don't see another brand with this type of "custom" battery and hope I never will.

I'm in agreement with your concern about custom cell necessity. Although I did read the "custom" Olight cell, I never imagined the light wouldn't work with conventional 16340s.

Vapcell (White wrapper) INR16340 800mah 700A max discharge, Efest (red wrapper) IMR 16340 700mah 7A discharge. These are a couple of 16340 cells I use.

There is short circuit protection, no problem, I shorted them many times, when adapted them to work in a stun gun, and they continue to work well in all the lights. Vapcell beautiful, they have more capacity.

I'm talking about the Olight cells, I know the light itself does have protection even though voltage appears on the bottom contacts. Maybe I didn't let the test probes on long enough, but a bunch of amps were available from the 16340s themselves. Perhaps it takes a second or more for protection to kick in, but I stayed connected only ~1/2 second.
