p60L query

for those in the know...is it safe to run the p60L w/ a single 3.7v rechargeable Li-ions (17500 or 150S) & vise-versa?
thanks

it works, but may not run in regulation for long(if at all)

thanks very much.

That's the only way I run mine. They run a VERY long time in regulation for me. Much longer than with a pair of 123 batteries.

that "regulation" you see is more likely due to the constant voltage that Li-Ions can hold rather than the light being regulation. The much longer runtime is a tip off, there is no way a 17670 or similar sized battery can put out more capacity than a pair of primaries, especially when moderately driven.

My G2L runs noticebly dimmer on one li-ion battery than primaries. It also depends on the Vf of the LED, but in general a Li-Ion battery would give shorter runtime than primaries unless it was a high-drain situation, in which case the P60L is definitely not.

I had 2 G2L's and tried one with the SF 123A's and the other with a protected 17670, as said above the 17670 was not as bright to the naked eye, no idea of numbers just not as bright.
