Is this possible a protected 17670 Li-Ion rechargeable 6v under load

Is the possible for a manufacturer to make a protected button top 17670 Li-Ion rechargeable that is 6v under load? That will fit SF 2 cell lights incandescent/2 cell led lights with out being bored out.

I don't think so. I'm pretty sure LiIon's are always going to be 3.7 V (Or less if they are stepped down). This is just the design of the LiIon.

If you are looking for a rechargable option there are bulbs out there that are designed to work with one LiIon. A simple direct fit exchaneg. I am using the LumensFactory one on occasion and am pretty satisfied.

In a sense, yes. However, to do so, it would cease to be a cell and become a battery which is by definition two or more cells connected together (usually in the same physical packaging/unit.

This would be accomplished in the same fashion that is done in, for example, 9V batteries, or 6V lantern batteries (which consists 4 D-cells, or is it F-cells[??? sorry, i forget], connected in series in the same unit).

The upside would be achieving 7.4-8.4 VDC in a single battery, but the downside is that the stored energy or capacity (in terms of mAh) would be reduced - approximately halved.

The external dimensions would, of course, have to remain the same, and no reason why these dimension couldn't be maintained as they are now.

i'm NOT saying that doing the above would be a good idea. i'm just saying that i don't see why it's not possible to do this as has been done in other cases.

Here's a question, are the Li-ion batteries commonly spoken of in these Forums, actually batteries or cells? The answer lies in what the voltage is for the particular chemistry employed in a single Li-ion cell.

The Li-Ions we talk about are single cells, nominally 3.7V each.

If you could manage to squeeze in a tiny voltage boost circuit somewhere above or below the cell, you might be able to get 6V out of it. Since most lights' battery tubes have springs, you could probably fit a little something extra in there. It'd have to be really thin, though.

Your easiest option would probably be to use those aftermarket LF LAs, though.

That's correct. They are single cells. There was a clue in the prev. Post, viz. "it would cease to be a cell and become a battery".
