Rechargeable 123's in a G2L?

[waynephatg]

I have searched the forum, but haven't yet found a definitive answer. Can I safely use rechargeable 123 cells in my G2 LED Nitrolon? I have heard things about unprotected this that and the other. Could anyone shed any light on this? I was looking at uniross 3v R/C cells.

I would appreciate any feedback.

Thanks!

Mdocod's guide (above) is a fantastic reference.
Short answer (excerpt):
G2LED, 6PLED, Z2LED, C2LED, G2ZLED, Or any 2xCR123 size unit utilizing a P60L
Battery Size: 2xCR123
Regulation Type: buck
Recommended Input Voltage Range: 4-9V (estimated)
Recommended Rechargeable option: 2 3.7V protected LiCoO2 RCR123
Rechargeable alternatives:
1. 2x 3.0V LiFeP04 RCR123 (least runtime)
2. 2x 3.0V "voltage regulated" LiCoO2 RCR123 (less runtime)
3. 1x 3.7V 17670 size LiCoO2 (drops out of regulation during the run, extended runtime though)

My 1.5 cents, alternative #3 would be the best alternative if you wanted something else besides his recommended option. Somewhat less output but better runtimes and a single cell is a somewhat safer system due to voltage balance issues between two cells.

Enjoy,
