Question about VCT4 and current build...

[Everpresentnewb]

I have a Sigelei 100+ mod with two VTC4 batts in it. My current build is .15ohm. Looking at steam engine that should be fine as I have a 20% headroom, but since my mod is dual batts, that is actually 40% headroom right?

I have read ohms law, and every other sticky I can find on multiple forums, and I think I know what Im doing. I do know that even when I ran it at 90watts the batts never got warm, but then I started thinking... Just wanted to check with smarter people than I on this. I normally build at .25 to .5, but I was playing with 24g Parallel build and ended up with a .15ohm dual coil set up. I have never been able to comfortably run higher than 60w with my normal builds but this thing is sweet all the way up.

yes I know Im really representing my user name by asking this, but I just dont wanna end up with a hand full of fuck here.

Vtc4 is 30a continuous so just 1 batt can serve this build, 2 of these in series can serve .08 if your throat can handle it and if your batts are real. Sigelei can fire down to .1 so with all these statistics in mind you should be ok.

I thought VTC4 was 20 amp...

 

[martinelias]

No sir vtc4 2100mah 30a continuous 60a pulse internal resistance of .014
Same as vtc3 only vtc3 is 1600mah and internal resistance is .013

To answer your question...The batteries do split the load.

Sigelei's are series regulated mods. VTC4s are 30 amp batteries. They're the good stuff for this because to operate at its full capacity the Sig needs 30 amps input current. However, these are series so you're still only getting 2,100 mAh and 30 amps. However, again, this is regulated so voltage is whatever you want it to be up to 8.5 volts.

The mod won't fire below 0.15ohms and the lower your ohms go the less voltage it takes to reach higher watts, and it cuts off at 100watts. In series with VTC4s you have a possible 252 watts. You're well within your limits with this mod.

Its the wattage on a regulated mod, not the build. Well, within the limits of the mod that is. Regardless of the build, 90 watts is running that thing near the top of its limits. If the batteries don't get warm, awesome. Keep rocking it...

Coil current and battery current aren't the same in a regulated mod. In other words, the resistance of your build has jack shit to do with the amount of current being pulled from your batteries in your mod. Your batteries cover the max input current of your mod. If your mod will fire it, your batteries will handle it.
