so I made a flashlight mod. I bought some enercell cr2 3 volt batteries and I get voltage to the fitting ( around 5v) but when i attach an atty to it I get nothing???? If I put my 14500 3.7v batt in it it works fine. I also tried stuffing my cr2's in my 3.7v box with no atty my led lights up and I get power to the fitting. Do these battys not put out the right amps or something? I am lost. Any info would be helpful. Thanks guys!

Well I'm sure that there are enough minds around here to get you up and vaping.
Do you have any pics of your mod especially the wiring?
I have used CR2s they should work just not going to last to long.
Have you used that same atty on anything else?
Edit:
Are those batts rechargeable ?

I have seen something like this before where an atty wouldn't work on one mod but would work on another. a few times it came down to the atty connectors either in the atty or the mod. first I would try to lift the center pin in the mod just a little bit and screw the atty down very slowly, not to tight. But I have also seen stacked batts pushing just a bit to hard inside the mod and opening up the circuit, you did say that it worked with a single 3.7 ??
You should be getting 6volts with 2 CR2 batteries fully charged. Perhaps they are not charged and your reading 5volts with no load. Once the atty tries to fire the voltage is probably dropping below the operating voltage. Measure each battery separately.
Did you take the atty connector apart to solder the wires to it?
(Removed the center pin)

I do understand what your saying, I got some bummer cr2s from the rat shack one time too. but,,,, have you tried lifting the atty connector's center pin scene we started this conversation? I'd bet that is the problem or you have a torn insulator between the center pin and the outer housing. just a small hole in it may only short out after the atty is on it.

Well I did ask about that. If there not rechargeable, well then that could be the problem, I'd bet they had them on the shelf for a year.
heres a link to the battys they are rechargeable. All the connectors are fine, the center pin and isolator is fine.

Yeah. +1. Also, some flashlight mods only work in the dark. Try turning off the lights.........
Seriously, switch batteries. Also check that you don't need a spacer, but since you are getting voltage.... switch.

Thanks for the link. I sure don't think those are rechargeable batteries. they are just Lithium batts not Lithium ion.
If they are not already 1/2 flat. I made a 3.7v mod with some of those and got exactly 5 puffs off of each one of them before they went kaput.

Those batteries are 800mah rated and should provide enough amperage. You should be reading 6v with both in series. If you are reading 5v with no load, they are stale.
A normal 510 runs at 1.3 amps or so to a 2.5 ohm atty assuming 3.2v under load. I'll bet you are not getting the voltage under load to warm the atty to temp.

The 3v reading on the separate batts sounds OK but, if I read this right,, the stacked reading is with them installed in the mod. Try a reading with them stacked in your hand. If that is 5v the batts are bad. If it is 6 v the mod has an issue,
I agree. He should be seeing 6v at the connector. If he's getting a 5v reading with no load, they are most likely going flat with an atty load.
