Dual Twisted 28g on Stillare RDA Slow to heat up?

[leeson]

I just got the Stillare rda and I put a twisted 28 dual build on here. Its 0.4ohm and im using sony 18650 30a battery. I have a marxsus and a magneto mech mod both do the same but it takes allot longer to heat the coils then ive seen ever before with this same build. What could the issue be? Is there something wrong with my RDA? I know 0.4 with these batteries should kick ... pretty quick.
Any help would greatly appreciated thanks.

Sounds like mech mod conductivity issues. Have you tested (or had tested, if you don't own the tools) either mod for voltage drop, or continuity/resistivity?

 

[vapdivrr]

flux is right, if its not loose coil connections then its voltage drop in mods. all mods will have a certain voltage drop and depending on the specific mod some are greater then others. usually the lower the resistance the greater the v-loss will be. there are a few things you can do if this is the case, for one make sure all contacts are free of oxidation by using a polish and q-tips, every point of contact in mod and atty should be cleaned weekly. also connections should be tight, like if there is an adjustment between the batterys and mod, any rattle or loose contact or spring can create more v-loss. also certain batterys create more v-loss but since you have the sonys your good. if all that is done and your still having issues then increasing resistance can actually create more power sometimes. I would scrap the twisted 28g and maybe try single 26g coils, that should speed things up, if not scale back to twisted 29 or 30g.

What he said. Can't think of anything else.

yea I am not really sure guys, I have used both my mods the magneto and the maraxus. I have used both of these with this exact set up on other rda's no issue at all. its only this new rda thats giving me an issue.
I will try to clean the contacts and everything really good but I know its not the mod because I am using the IGO-w on it now and it fires perfectly.
not really sure what it could be. I hope its not a bad RDA

 

[vapdivrr]

could be the atty I suppose although im not to familiar with it.

Curious... to see if what you have lines up with what you should have. If you don't mind...

• Is it genuine Kanthal package wire?
• Twisted huh? What is the distance between each "ridge" of the twisted wire?
• How many strands to make your your finished wire?
• What is the wrap count?
• Compressed coil?
• What size coil ID?
• Approximate tail length to posts?

OK so I am getting it to fire now on the one mod but not the other so its not a problem with the atty or coils, its vaping like a beast on the one. allot of vapor but the magneto still fires it weak. I will post pics just to show you guys and thanks SOOO much for all the help so far.

Yep... sub-ohm can really cause mech resistance issues to stand out. I gifted away my Magneto a long time ago... honestly don't remember what the guts look like. Re-post in the APV forum and I'm sure someone who's into Magnetos will have a list of possible faults and fixes for yours... if basic cleaning doesn't work out.

The questions I asked, would have allowed me to determine if your resistance was your target (if you had a target), or a combination of your target and an internal RDA resistance... and separate them, if it were the latter.
See my first sig line hyperlink for "Steam Engine". Without knowing gross conductive wire length - post to post, it will allow you to take your variables and produce a accurate coil model... even with twisted wire. ;-)

Cheers

Try raising the ohm load to about .8 and slap it on a DNA30 with more voltage going through there you will light up quick. 24 watts will give you 4.4v

what? no wonder they call you Einstein .

what?

Sorry 'vapdivrr'. Call me anything you want... but late to free meal. ;-)

I figured that maybe - the OPs coil, being built from twisted wire, wasn't based on a specific target resistance value, but rather... just what ever it happened to end up - which would be the case with most twist wire builds.

'Dampmaskin' (Lars Simonsen) has recently included twisted wire / rate of twist as 2 new variables in the Steam Engine coil modeling software. If I knew exactly what the coil build was, I could build a model to determine if 'leeson's' 0.4Ω net was the result of the coils only, or a combination of atty resistance (granted, weird and highly unlikely) and coil resistance.

It was a long shot. Unlikely that 'leeson' would pay that close attention to or build twisted wire to such specific values.
But if for some strange reason he had, it might have allowed me to "prove" one way or the other if the atty had an included resistance, that wouldn't show up in continuity testing.

After reading that load, I'm almost ready to say... "ah what?!?!"

you know i was seriously trying to follow that, and then i said wait a minute.
