Good evening everyone. I came to hijack this thread for a post. The OP of this thread, Breaktru is turning ECF Veteran tomorrow. A big event and milestone – happens only once at ECF.

If any of you modding friends of his would like to wish him happy turning– please feel free to visit the pre-vet forum at the link below. If you would like to drop of a graphic off for his thread, his theme is Lady Gaga. If you’re a vet, you can go directly to his Welcome Thread in the Veterans Forum. If you’re not a Veteran yet, the Veterans will deposit it for you. Thanks guys and gals – have a fun, relaxing weekend.

I put this circuit together out of spare parts today... had a broken book light for the enclosure... clunky but it vapes very nice.

I used two 14500 in parallel... they are the lame protected ultrafire batts... with only 1 in the circuit I get about 1 second before it cuts out... with both in there is no cut out. I'm sure with aw imr I could use a single cell with no problem but why not 2 for the extra mah.

Anyway, thanks for posting the circuit and the resistor diagrams.

Great Chris, It should have worked with the one 14500. Is the cut out with all voltage ranges and what atty resistance are your using?

Thanks! The cutout is with a 2.3ohm joye brand 510 atty at 4.15V and higher, loaded. The batteries seem healthy... they work fine in a single cell unregulated box... the two I tested with read 4.06V tested separately.

Check the watts chart that's floating around ecf. You might be way over the 12watt limit. Also make sure your using AW IMR batteries. This always helps.

Good luck!

The cutout is occouring at about 7.5watts and higher...about 1.8A.

I assume it's just the battery protection hitting it's maximum current. I don't actually know what the max discharge current is for these batteries but if the battery is 900mah and the max discharge current is 2C then the protection should kick in at about 1.8A which would give the result I am getting.

Chris, I have a 2.0 ohm atty on it now and it worked great from 3.99v to 5.5v measured under load and ONE 14500, 900mah Trustfire. AW would be better.
Also worked with a 1.7 ohm atty but didn't try a range. Set it to 4.08v just to try it.
A 1.3 ohm didn't work. Cut out due to overload. The 1.3 ohm worked good with ONE 18350, 800mah, same circuit.

So in-conclusion (IMHO), It's the battery that is causing the cut-off with your atty/voltage selection. Not enough ummph. LOL
