Jetbeam M1X batteries.

Hi everyone, been a while since I've lurked the forums, but needing your help.
I've got the said flashlight, and not used it for years, I needed it the other day and no batteries in it, so my question is, what batteries do I need and can I use rechargeable ones as would prefer to use them.
Any help appreciated.

I found an old selfbuilt review on here that's very detailed.
Here's some text taken from this review:

Specs (from the manufacturer):

• LED: CREE MC-E
• Max Output: 450 Lumen (Torch Lumen) / 700 Lumen (LED Lumen)
• Reflector: aluminum reflector
• Lens: Toughened ultra-clear mineral glass with anti-reflective coating
• Material: T6061 T6 aircraft aluminum alloy
• Finish: HA III Military grade hard annodized
• Battery: 3xCR123A, 3xRCR, 4xCR123A, 4xRCR, 2x18650 Li-ion
• Input voltage: 6.5-18V
• Switch: Forward clickie switch
• Waterproof: Accord to IPX-8 standard
• Dimension: Bezel diameter 63mm, Body/Tail diameter 25.4mm, Overall length 198mm
• Weight: 285g
• Output & Runtime: 3xCR123A Max Output (450 Torch Lumens) for 100 mins, Min Output (10 Torch Lumens) for 150 hours
  4xCR123A, Max Output (450 Torch Lumens) for 130 mins, Min Output (10 Torch Lumens) for 200 hours
  2x18650, Max Output (450 Torch Lumens) for 3 hours, Min Output (10 Torch Lumens) for 300 hours

From the looks of things you'll need the extension tube it came with to use 2x18650 (or 4xCR123).
This light looks like a great light to mod, you could easily swap the LED/MCPCB out.
I wonder how well an Osram 1mm2 would focus in there, would be fun to try.

Thanks for the reply,
Unfortunately I don't have the extension tube, wish I could find one to purchase. So basically the only option I have with rechargeables is 3RCR's.
Would two protected 18500's work, if you know?
Thanks.

It should providing there's enough length in the tube. I noticed that the light doesn't have a spring at the head so it might be tight.
Considering it specifies that it can take 3x16340 then I think you should be fine with 2x18500.
