I just bought my first mech mod and I am not really happy with the battery life or power. I am using a Efest 2500, 18650 3.7 volt battery. I have a Valkyrie mod. Currently I'm using a 26 gauge kanther, duel coil. I'm not getting much cloud production and wanted to also know if there is a better gauge I can use.
Looking for Advice

welcome to the ECF.. i don't have a Valkyrie,but i would guess it's not your battery or the wire gauge . hopefully someone will come along and have all the answers for you. good luck.
Hey Ally, what's the ohm's of your build and rba used? Type of wick and coil used would be helpful too. It's most likely a combination of things but without more info tis tuff to even guess.
Not having a secure trap on coil leads can cause many issues and concerns. The more amps one is pulling from a batt, the shorter vape time per charge. Densities of wick through coils and in juice well or channels can cause deficiencies in vape production and satisfaction/flavor. proper air flow......build location to air intake............. Just saying.
Vape long and Prosper.!!!

I'm using organic unbleached cotton balls for wicks, It's a duel coil, 26 gauge. I've checked and rechecked the connection with the coil. Ohms is 1.48 with my calculations. The RBA has adjustable air flow as well.
1.48 ohms may be too high. That is quite a bit of metal to heat up on a mech mod (that is a mech isn't it?) Try building a little lower and I recommend using a meter to verify your atomizers resistance.
Just a note on that battery you have - I believe it is really a 20A battery, not 35A. I may be wrong though. Probably shouldn't build any coils lower than 0.25 ohms if you decided to sub-ohm.
Battery says 35A. I didn't build the coil, the tech at the vapor store I go to built it for me for the mod so I assumed he knew what he was doing, I may be wrong in that assumption though haha. Yes it is a mech mod. I may have calculated it wrong as well, I don't have a meter yet.
I forgot to include that I believe it is labeled wrong. The cell inside the Efest wrapper is actually an LG 20A cell. I just found the link on the site here: http://www.e-cigarette-forum.com/fo...he2-2500mah-imr-icr-30a-20a.html#post13166415
Edit: Doesn't seem like the guy set it up well for you. I personally haven't had any luck with high ohm + lower gauge coils on a mech mod. I was about to suggest a build, but towelie's below looks like a good place to start.

Purple Efest's aren't 35A. They're actually LG HE2 batteries with a purple wrapper. You need a meter and some wire. I recommend 28ga which you can always twist to make lower res (higher guage) wire. Start with a single coil around .6 ohms and I think you will be pleased. The tech should have told you what the ohms were. Welcome btw!
So if it is 1.48 ohms total, what would it be with dual coils? I'm having some difficulty calculating it out.
Thanks guys. That really sucks about the battery though. Pretty peculiar. I'm checking out meters now. I definitely don't want to burn anything out!
Would you have any suggestions for a better battery or do you think it's fine even though it's mislabeled?
The battery should be ok as long as you don't push it past it's limits and use it safely. You can find meters all over. There are some cheaper ones like this that work just fine and ofc there are better and more expensive ones.

Do you have an ohm meter of mod that reads coils ?
When putting in the info to a coil site make sure you selected dual coil.
1.4Ω dual coil would be two coils at 2.8Ω each giving 1.4Ω total.
If you did two coils at 1.4Ω it would come out at 0.7Ω - or 1.4Ω if only one coil was making a connection because then it would be a single coil.

Hello and welcome to the forum Ally. Glad to have you here!
If you are new to mech mods and rebuildables I highly recommend you spend some time with Baditude (one of our resident battery experts) and visit his blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.
Baditudes Blogs. The blogs regarding mods and rebuildables are listed below:
