Those of y'all wanting rechargeable 123s, Surefire offers a LiFePO4 kit now.

There are many manufacturers of rechargeable 123s and without lots of research, you can get yourself hurt pretty easily. The SF kit seems like a good solution for those that do not want to spend the time and resources on research.

I was wondering if they were ever going to offer something like this, too bad the runtime is half of what it is using primaries. I wish you could fit an 18650 in their lights without having to buy an aftermarket body.

I wonder how well they deal with recoil?

For my weapon lights, I won't use anything but high quality primaries.

For my other lights, I have AW protected Li-ion batteries.  But I have to admit, $29 from Surefire for that is a pretty modest price.

I wonder what would happen if you put three of those in a G3 LED?   I have an old Surefire KL2 head, using a cell extender, I put it on an M3 and put four rechargeable Li-ion's in it, which was pushing 16 or more volts.  The higher voltage didn't bother it one bit.

These are LiFePO4 batteries and not Li-Ion. They come fresh off the charger at 3.6V on a open circuit. They drop down to ~3.3V under load with a nominal voltage of 3.0. Surefire states not to use in incadescents and only in the LED lights.

I would not use rechargeables in a weaponlight.

I use rechargeables for practice and general night time mayhem and primaries for bedside duty.
