Can I use unprotected cells in my Eagletac T10LC2 ???

Can I use unprotected cells in my Eagletac T10lc2? I have purchased AW RCR123's but had a couple duds. What protected or unprotected RCR123 options do I have ? Once I have had problems with a certain item, I don't use it again. So that I why I am looking at other options. The Powerizer unprotected RCR123's seem to do well and I have heard good things about Solarforce cells also.

no dont.
use primaries, or use protected li-ion when using series pairs in that item.
if you had to SWITCH, because you got a dud, or cant make them work right, then you could go with a li-fe-po which still has issues, but is safer WHEN it doesnt use protection. li-fe-po has less total capacity.

dont you have the option of using a single protected 18650 in that?

i would have to see more graphs on it, but you might be able to use a unprotected 18650 single item li-ion cell (without destroying it) , because i think it cuts off before you would drop its voltage to low. normally a good protected 18650 would have a really long runtime on an item like that.
can you find me more graphs on the 18650 running in it?

oh i was looking at the wrong line, , ok the 18650 running in it is basically unregulated, a dwindling dd type of graph, so a UN-protected 18650 would be a possibility as long as the USER pulled it when its really dimming badly, and recharged it. a lot of people would not like the brightness of it then.

and i am editing the other post, cause i goofed.

Based on that graph in the review, the single 18650 will be down ~20% from the initial regulated output level of the RCR123s (they start off about the same output) after ~38 minutes. Oh... and then the single 18650s delivers another 2 hours above 50% output....

Lets remember now, it takes about a 35% difference to SEE.

The T10LC2 is one of the many 18650 lights that has a relatively low over-head voltage requirement to run close to full output, much like other purpose designed 1x18650/2xRCR123 lights. (like the TK11 and others)... So a freshly charged single li-ion cell starts it off close to 100%.

I would have a really hard time justifying using anything but an 18650, with CR123s as backups in that light. Considering that you would not be able to see the difference in output in the first 38 minutes anyways. However, at 39 minutes, there would be a very noticeable difference, in that the 18650 powered light would still be on.
