Got the NEW Maglite ML25IT 2C

[fivemega]

These batteries would be 9v.

No,
Three serial regulated Li-ions have 9 volt at rest (no load).
Under a load of 1~1.5 Amps they will drop to 2.5 volt each. Similar to primaries.
Remember you are getting power from built in circuit board not directly from battery and those boards are not capable of same current delivery as bare cell.
Another world, you won't gain anything if you use 3 of 3 volt (NOMINAL) batteries (even if they fit in 100mm space) compare to pair of protected 18500

This is my experience.

1) What is the ID of the battery tube in mm?
2) Total length of a 2 cell battery tube?
3) Will an incandescent Maglite C switch fit into the tube?

thank you.

1) 26,3mm
2)109mm excluding tailcap
3) no idea

 

[carl]

Thank you for the info!
Most 26650 Batteries are about 26.2mm so they should barely fit but maybe slightly too tight.
Looks like the Mag switch should fit too, especially since if its a bit loose, the set screw will compensate for any bit of looseness and if the switch is a bit tight, a bit of sanding around the OD of the plastic switch should make it fit. Of course, a hole will need to be drilled for the on-off button.

 

[vicv]

Why though? Just buy a standard 2c. That's what you're turning it into

Or, it would turn into a 1x22650 or 1x21700.

Note: The incandescent tube ID is too small to fit a 26650.

 

[carl]

Does the tube have a C-ring in it to hold the switch in place like the incandescent model?
How does the switch stay in-place against the battery spring force pushing toward the head?

That 26.2mm is not accurate and correct for protected cells.
There is no guarantee to fit in even 26.5mm tube.
No cell has absolute diameter size in every direction and not perfectly cylindrical.
Mentioned flashlight does not have similar switch as old 2C, 3C, 4C M*g.
By the way, each C cell is about 50mm long and 2C tube has space for 100mm long batteries plus few mm extra.

The ML25 is also too small. 2X protected 21700 in a 3 cell light in a spacer with a 6 cell bulb/drilled out reflector is the way to go. Or you could go with 1X 21700 in a adapter with a 3 cell bulb in either a 2 or 3 cell ML25IT.

 

[Olumin]

I do fit 2x 26500 in 2c ml25 with 6cell bulb. It does work but its a very fight fit. Require magnet to remove betteries. Go 2x21700 in 3c ml25.

Got a 2 and 3 cell version recently. These will remain stock. Actually they will probably remain in the package for a while.

The 2 cell is S/N 12,xxx where the 3 cell is S/N 1,5xx.

Back in 016 I recieved a few 2 cell versions from the same supplier with sub-100 serial numbers. The 3 cell were 5xx and up.

In 019 I bought one of each and the 2 cell was 12,xxx while the 3 cell was 9xx.

The supplier (ZBattery.com) shows they are nearly out of stock on all 5 colors in both 2 and 3 cell versions.

It seems that these are not popular so they were discontinued.

The 2C is so beautiful but I really don't like that 2-step reflector. It makes the beam pattern so ugly - too many circles. I am looking for a replacement, probably aluminum and with OP.

 

[vicv]

Ya it does make for a strange beam. But it cleans it up more than a standard full size mag reflector and somehow increases the throw. I can't believe how well this thing throws. And in use, outside, I can't see any issues with the beam. I know I did ask FM in his "what is missing" thread, about making an aluminum reflector for these, maybe he will answer soon. I'm not sure how popular these are though outside of this thread

 

[Olumin]

I frosted 6-cell bulb with glass etching cream and the beam is perfect, no rings or artifacts whatsoever. Better then most LED beams Ive seen. But you gonna loose a lot of throw. Id say it cuts throw down to 1/3 stock.

 

[vicv]

Yeah for me that is unacceptable. I couldn't care about a couple little artifacts in the game. I'm not white while hunting I can't see them when I'm out and about using my light. Maybe even if I could I wouldn't sacrifice performance just for a perfect round beam

 

[Olumin]

Really wanting a lightly textured alu reflector for ml25. It will also loose some throw but not much compared to frosting. That being said I decided to frost the whole bulb since it was the first time I tried it with the cream. Normally I recommend only frosting upper third to half for minimal loss of brightness, and not going too far with the frosting to minimize loss of throw. Ill get more bulbs and try it out and compare. maybe take some shots.

 

[konifans]

Olumin, which etching cream are you using? I found something called "Armour Etch"...

Brand called pentart. Armour Etch will work.

Thanks! Will give it a try!

 

[Olumin]

So do G4 Bi-Pin fit in Maglite? Could you run 2x 21700 IMR in 3c mag with G4 Halogen for crazy brightness? When using standard 3c mag I can get a alu reflector & glas lens. Read about Philips 5761 30W G4. Peeps have used them in Mag mods as I have read. Over 700 lumens. Or is a adapter needed? Dimensions of G4 do not line up with standard MAG-num star bulbs. Just curious.
