Old Trustfire at overvoltage

[mudglutten]

Have been rummaging through my old collection and came across my old C2-T60. I had nothing to lose, so stuffed a couple of 16340's in instead of a single 18650. the lux doubled and nothing went bang! Has anyone tried this on a sustained basis? Does anyone have a spec for the drive electronics to give an idea of whether they can cope? Thanks.

Plain luck.

Especially (very efficient) 1*Li-Ion drivers drivers can be very sensitive to overvoltage

Must agree. So far, OP has been very lucky.

Or the cells are junk and lack the power to blow up the driver. Not something i would do to a light i cared about.

Thanks for the responses. Nah, it's not a light I care about, so I tried a sustained run with protected cells. It's tough! It ran for about 3 minutes before becoming insanely hot (too hot to touch) and cutting out, with no prior diminution. After cooling, it ran happily, with no apparent detriment. That's it, experiment over, I don't have appropriate PPE and fire fighting equipment to continue .

Interesting experiment though...

Perhaps you missed the post title, the flashlight is a "Trustfire"

Pretty much any "old" flashlight, with "fire" in the name (not being a SureFire, that is) is pure junk to start with, so I'd say no chance of being a cared about light.

And yes, I wasted my money on trying a couple of "Trustfire" lights, back in the day, and yes they were junk.

But they did save me money in the long run, as I then learned NOT to purchase any more lights with "fire" in the name, excluding SureFire, of course
