Ampage

[jtc]

So I've just got some SS fused clapton and above is my calculation on the dual coils I'm trying out in TC mode.
I'm using my Reuleaux DNA200 with 3 sammy 25'rs.
The ampage I'm drawing seems too high for the batteries to me though.
Am I wrong?
40 amps!
Can anyone tell me if I'm going to blow my face off with this please?

Using your locked figures above Steam-Engine reckons you have only 28% headroom, but at least it's not in the red, but you are getting close and yes Amperage was 40A:



Just realised you are talking about SS and TC, the DNA200 probably will not hit anywhere near the 180w under TC at the normal temp of 430-450F or even at 500F

No the DNA 200 spec has max output current as 50 A continuous & 55 A peak, it will be pulling far less from the batteries (input current).  Ohms law calcs don't really help with regulated mods, it's easier to work in watts.
EG
Power: 180 W as in your calc
adjust for 97% efficiency losses 180 / 97 x 100 = 185.6 W needed from the batteries
when the batteries are at their lowest is when the max current will be pulled
current from batteries at 9.3 V = P/V = 185.6 / 9.3 = 19.95 A, if the batteries were full it would be 1865.6 / 12.61 = 14.72 A

Awesome thanks VapingBad
All seems well right now with the 200 update and I'm getting an excellent vape

[jtc]

In fact at that I'm going to 200w
Never thought I'd do that but this is awesome

[VapingBad]

I told you you'd like it jtc

[jtc]

I do but the 200w got put down to 100 atm as it was too much

[SteveF]

I wound some fused SS316 clapton wire on Thursday, call it a therapy moment (although the neighbours might not have been too happy at 8am).

0.45x2 c/w 0.16 wrap. spaced build in the griffin came out at 0.199 ohms.

Escribe says the rolo is peaking 20amps, holding temperature at 12amps

very very smooth with the SP3 tc mode 210c @ 90w

[jtc]

Koolio
I'm at 80w with a 120w preheat and 460f
It's a banging vape

[SteveF]

I'm not even bothering with preheat, I tuned it down to lose the initial spike and then thought why bother... all it was doing was making it crackle.

Do you lock the ohms?
My rolos seem to lose consistency and I really don't see why.
Ive always had this with ss on 4 rolos and numerous atties.
I thought this update would sort it but no.
I'm on the verge of kanthal only

[jtc]

It's like sometimes it just goes weak and I have to get the mod to re-recognise the coil before it performs again.
It's so annoying

[jtc]

This happens on my foggattis as well so it ain't the rolos.
I feel I must be doing something wrong but gawd knows what.
Nickel works fine but ss pfhaaaa it's doing me head in

It will be a connection somewhere, probably the atty, 510 or 510 ground, but if it's all your DNAs then it's probably the atty.  If you have to lock ohms 30-45 mins after fitting a new coil so it has a chance to refine the res first.

no, I had one tiny fluctuation 0.01 yesterday but the mod had been left in the car....its a black car
I was just pleased that the griffin hadn't emptied itself into the cup holder.
I was that close to nichrome /kanthal only again too, SP3 seems to have done it but my temperature preferences are creeping up again.
Its actually the first time in over 6 months that this griffin has worked as intended....kind of. It vapes, it hasn't dumped the juice  I almost like it.
Are you using spaced coils?  I made one contact coil, awful.
