XTI Procyon and 3.7v li-ions...

Does anybody here own this light and use rechargeables with it? I ordered the light today, it should be here next week, and I was wondering if I could use the 3.7v batteries I already have.

Anybody? Any info would help, I don't want to ruin the light.

I have one and I couldn't get the regular 3.7 RCR123s to fit in. I did have success with the smaller 3.0/3.6v LiPO4 cells. They have less capacity but fit in the light.

Thanks for the info. So if it handles 3.6 volt batteries fine, I should be able to run it on my 3.7's... if they fit. Any idea where I could buy some of those LiPO4 cells in the US if I have to get them?

I got mine from battery junction (

but they are available other places as well.

I'm going to purchase the 900mAH ones soon enough too, hopefully they will fit.

I tried Ultrafire RCR123s in my XTI and the back cover wouldn't fit, but the LiPO4 worked great; great way to save on batteries.

Thanks a lot for the help. I really appreciate it.

No prob! What do you mount your XTI to?

I mount mine on my CZ P01 but it's a little loose...

Well, it's not here yet, but I will use it on my 1911.



There's a green laser mounted on it in the pic, it's cool, but it moves inside the mount when I shoot it so I haven't been using it.

Got the light today, so far I like it. Still not dark out to go play yet...

Neither of the latch bars that came with it would fit my rail well; one didn't fit, the other did but very tightly and it wouldn't come off once I had it on. The bar was a bit to tall, so I grinded it down a bit and polished it, now it works perfectly. It comes off easy and goes on easy while still being fairly tight to the rail (no rattling whatsoever).

I'll post a pic of it mounted when I get the chance, and hopefully get some comparative beam shots with it and my Gerber RX-700 (slightly modded to fit a cree r2 drop in) and do reviews of both the lights.

Also, my 3.7v CR123's fit perfectly. The light runs fine with them.

what brand of rcr123s do you have?

I'm not sure, I got them from a guy off ebay who imported them. They came with a Since charger, not sure if that's the battery's brand though.

Unprotected cells will probably fit, while most (if not all) protected batteries will not.
