Protected Vs Un-Protected ?

[how2]

Hi all

Thinking of buying
TrustFire Protected 16340 880mAh 3.7V Rechargeable

or


TrustFire 16340 880mAh 3.7V Rechargeable

What i want to know is

1) Which will last longer in terms of run time? and by how many mins?
2) Which will get less hot while inside the flashlight?
'
Heat is a concern for me.


I has an excellent charger which does not over charge and i am not worrying about under charging.

But do you worry about "Over Discharging" ?

And is this a light that uses more than 1 cell ?

ONE use without any means of undervoltage protection and I guarantee You a damaged cell.
On simply cant stop the light be4 the cell is too depleted. As soon as our primitve eyes notice the output going down, it is already too late.

always get a protected cells. If you have GOOD charger and light that equipped with over discharge protection then unprotected may be use otherwise damaged cells is most likely.

Not worried about over discharging the lights that i have only use one 16340. Every time that i have over discharged. I have no problems. That volt does down to 1.5 etc then if i leave it, goes back to 3.25v. My lights lasts longer on unportected 16340, but does get dimmer. If i use protected cut in starts at 3.85v.

1.5v?!?!?!

You definitely don't have the experience required to safely operate unprotected cells, so protected should be your ONLY choice.

Yes 1.5 volts means you probably are running them ALL the way down. You're asking for a venting or explosion on the subsequent recharge. I'd only operate unprotected cells on a single cell light with either under voltage protection or no boost circuit because when the voltage goes below the vf of the led it won't operate but you'll still be at a safe voltage at the battery. On multi cell lights never run unprotected.
