Just got invited to my first cloud chasing competition

good luck on the comp ... may you advance to vape another day

Thanks for all the tips. I really didn't expect so many people to start off saying I'm stupid instead of giving advice, but alas it's the internet.
So on to the technique, I have been practicing what I have seen on several videos. My current technique is to preheat the coil then exhale through the rda. Roll shoulders down and collapse diaphram. Then hard inhale while while straightening shoulders to expand diaphram. Followed by a hard exhale to push vapor as far as possible.

Tell me what I'm doing wrong and help me get better.

I think you should collapse the shoulders down and roll the diaphram instead.

I agree with the keeppower battery ive been using one for 3 days now constantly and the charge is still at 3.9ish. Its also the highest amp rating 26650 out there as far as I know.

I'd highly recommend you read up on batteries and especially pay attention to what C rating is and how it relates to different battery chemistries.

A huge misconception I've noticed is that many think that a 2500 mAh 18650 battery has the same discharge rating as a 4000 mAh 18650 battery of the very same chemistry. This simply is not the case. The true amerage rating is based off of 3 things primarily. It's chemistry make-up, it's C rating (which is determined from chemistry and construction) and it's capacity. What this really means is that 10C 2500 maH battery can have a continuous load of 25A safely and the 4000 mAh one will have a 40A conitinous load rating. You can't just go off of it's an 18650 of the same chemistry make-up because the discharge rates are different!

Best thing you can do is to educate yourself fully on the battery you're using. Take a look at battery university's website on C-rating, battery discharge methods and lithium-based batteries information. I'd post the links but I'm not allowed to just yet.

i agree with your view concerning battery discharge rates.

i have been under the opinion that although batteries may be rated to run at say 20 amps continuous,
i have never seen or am aware off any manufacturers literature recommending one to design a circuit
that runs at that rating continuously as it seriously degrades battery life expectancy. the power is available for torquing
up a power tool or charging a circuit with a lot of capacitance. perhaps they don't recommend it for
liability concerns.
i am not saying sub ohming can't be done safely.i have not ever ran applications that required
pushing batteries to an extreme and was only aware of their extreme use in R/C applications
before joining this forum.
