Fixing loose cartridges on an M-401 electronic Cigarette
This is a quick how-to for fixing loose cartridges on the Evo and other M-401 / 402 / 403 style electronic cigarettes. MAD props go out to Sun Vaporer from the E-Cig forum for telling me about this fix. If you're looking for an e-cig forum, find a good one at www.e-cigarette-forum.com



OOoeu
Your the man. That trick works great I just tried it and it works great but I used a paperclip was really tight but it also fixed my problem with my light goin off in the middle of a hit also. Worked out great.
Seems that cap somehow reduces the sensitivity of the battery. Not sure the physics of it but removing that and punching the tiny holes in the cap made a world of difference. Now I get sad when that battery dies.
cool! i know the plastic disk you mentioned so i might just give that a try!
I popped the end cap off to expose the LED and then pulled the LED out whilst taking care of the wires. There was a plastic disk in there (contact shield, no doubt) which was HUGE...I cut that out and then scraped out some glue that was in there. After that I melted 3 clean holes in the cap and replaced it. My god, it's insane. It pumps out more power than the evo batts so I hget POWERFUL vapor and throat it. Love it.
well after reading the thread on the pilot batteries its no wonder you opted for the EVO one! lol
what mod did you do to your generic?
Yes, you are correct. I have 3 evo batteries 2 evo atomizers 2 pilot atomizers and 1 generic 401 battery which I have now modified to the point that I like it better than my evo batteries
I did another vid comparing the evo atomizers and pilot atomizers. Surprising results.
hi mate,
am i right in thinking thats a Pilot atomiser and a EVO battery you are using in this vid?
nice tip!
You're very welcome. I hope it helps!
Great tip man thanks for sharing
