In which of Peak's 123A models is it OK to use rechargeable lithium-ion cells (3.7-4.2V)?

:bump:woodfluter said:Archangel, if you check in here, could you tell me if you know whether use of the RCR123's is likely to reduce LED life to any substantial degree? Due to higher voltages? Or could speculate? Don't know that they have buck circuitry to bring higher voltages down, don't know enough to guess about overdriving LEDs. I like the McKinley HP and would really like to use my rechargeables in them as well as my HDS.
I've searched & read replies about this from MJ, but they were generic "yes" rather than specifics about impact.

One thing that makes protected RCRs larger in diameter is the strip that runs up the side of the battery for the IC to work. Another, I beleive, is the manufacturers use up all the space they can and possibly a bit more, since Li-Ions are at a capacity disadvantage compared to lithium primaries.woodfluter said:And why the heck are the RCR123's larger in diameter in the first place?
