Limitless Sleeve Mod, Slow Ramp Up Time

[Tesla109]

So I bought a Limitless Sleeve mod Aluminum with the light wood sleeve. I cleaned the contacts with warm water and soap as well as use Alcohol on the threads and contacts. I also use a nail file to smooth out the contacts.

Mod: Aluminum

Build: Dual, Stainless Steel 316L 10 wrap, Spaced. 0.25 Ohms

Battery: Samsung 25R Green

juice: 70 VG/ 30 PG

The mod gets hot after chain vaping. Even after warming up, there is still a ramp up time between pulls. The mod didn't feel hard hitting. Is there any way to further clean the mod?

Thanks!

Is it the Mod or is it the Build that is causing you the Slow Ramp Ups?

What Gauge 316L are you using? And what Diameter are the Coils?

It's the mod, I had a Kanthal build before and had the same issue. I used different RDAs as well as different batteries.

Coil is 3mm, 24 Gauge.

OK...

I could see how you would have the Same Problem with that build with Kanthal.

All I'm say'n is that if I put that build on one of my Mech's, I would get a Slow Ramp-Up Also. Dual 24ga 3mm 10 Wrap Coils is just kinda a Lot of Wire Mass for Mech to Heat Up.

My previous Kanthal build was 24Gauge 3mm, 6 Wrap Dual, Spaced. Also at 0.25ohms. Is there a safe build that has a better ramp up time? I've seen people that use this mod that fires instantly. :X

Thanks!

If you stay at or above 0.25 Total Ohms (0.5 Ohms per Coil in a Dual Coil Build) you should be OK with a 20 Amp CDR Battery.

To make the Ramp-Up Faster, you need to Reduce the Amount of Wire Mass to be Heated. ie: Use a Thinner Gauge Wire.

If you go to this site and fill out what you have for your current build, 24ga 316L, Dual Coil, 0.25 Ohms, 3mm Diam, you get a "Heat Capacity" of 111.77 mJ/K.

Coil wrapping


Now notice what happens when you Change the Wire Gauge to 26ga. The Heat Capacity Drops to 44.21 mJ/K. This means that the Ramp-Up would be Much Faster.

And if you went to 28ga (Probably would be Too Hot of a Hit), the Heat Capacity Plummets to 17.49 mJ/K.

Finding the Right Balance of Ramp-Up to how Hot the Hit you get can take some Experimenting. But you will/can find it.

Just Don't Exceed the CDR Amps you Battery is Rated for. And Always give yourself a Little Safety Zone by not running the Amps all the way up to the Battery CDR.

Strange, my Kanthal build had a heat capacity of 47.20 mJ/K. It also did not heat up well either.

Like I said, 24ga Dual Coils is just a Lot of wire to Heat up.

I run mainly 26ga SS Coils in my RDA's on a Mech. Don't like the Slow Ramp-Up/Ramp-Down I get with 24ga. And those are Single Coils!

Wire is Very Cheap. I would suggest getting a 50' Spool of 26ga & 28ga and doing some Experimenting.
