Well, praise be, the authentic flask is now coming in a SX 350 J version. My favorite board in my favorite form factor. Yes, that's an authentic VF with an authentic Yihi board inside.

I do wonder if it'll still be parallel, or if they go serial to get the higher wattage/joules out of the SX board.
I'm pretty sure it's still parallel battery connection.

It looks like the lobes of the side curves are no longer the same size. They probably needed more room inside to fit the J chip.

My Waidea flask is working just fine, I haven't had any "extra" problems with it but finally decided to go ahead and put an Evolv 40 board in, thinking about doing this one a squonker also but I kind of think I'll just put in the board and FDV v3 shorty 510. I already have everything I need to do it so I figure I might as well.

I haven't done a nickel build on my SXK yet, but I'm concerned that the -0.1 ohm inaccuracy is going o cause problems. Being that the lowest I can build is 0.16 ohms without hitting the minimum resistance imposed by the chip. Can I use the purity function to balance out this glitch manually? I've tried to find a simple explanation of how the purity mod work but I cannot so far, can someone spoon feed it to me please?

There's a good discussion of the low resistance issues with the SXK boards and ways to work through the problem with the purity feature in this thread.

I think what you might be interested in comes up fairly early in the thread.

I made some measurements with different atomizers and TC boxes and compared them with the Keithley Microohmmeter. The amount of inaccuracy depends on the Ohm value.

From left to right: SXK Vapor Shark - Kangxin Mini VF - Hcigar DNA40 - Waidea VF - Fasttech Ohm meter - Keithley 580 Micro-Ohmmeter

Atomizer----- SXK------KX M------DNA------Wai------Ohm m-----Keithley 580 Micro-Ohmmeter

FeV Nickel----0.11------0.15------0.15------0.16-----0.09------0.1491

K4 Titan-------0.42------0.48------0.49------0.50------0,44------0.4986

Rose Kant----0,95------1.08------1.04------1.10------1.04------1.0925

Rose2 Kan----1.06------1.20------1.14------1.21------1.17------1.2170

Orchfun ------0.52------0.61------0.59------0.64------0.56------0.6147

I've been using a 0.12Ω ni200 coils on mine for quite some time with great success. They read 0.08Ω on my SXK flask and the purity setting I'm using is 90. The SXK firing cut off is about 0.055 Ω which would be about 0.09Ω actual.

What do mean buy buttons? The little chrome covers that press on to the switch or the switch itself?
The ones on the Kx are part of the switches, the up/down is same as Hana(close enough) but the fire switch is an odd sized one, slightly larger diameter.

Oh Ya that's right, they cheaped out and just hot glued some hana style tactiles up in there. Just leave the pin out leads hang out of the flask through the button holes and just touch the ends of the wires together to change watts or fire. Simple fix. ;) Try varitube.com for some replacement c&k tacts.

I read all 40 pages of that thread and along with a sore head I now have a significantly better understanding of TC. Tweaking the NP helps to correct inaccuracies created by the low resistance reading, but it doesn't help with the fact that it limits the lower end of what you can build to.
The SXK Flask and VS clones will be the last TC clones I buy. I will save up for an authentic if get another TC mod as I've had it with these moody knockoffs.

@TheBloke I tried using your spreadsheet saved in my google drive and downloaded as a .xlsx and the drop down does not work.

Received my SXK rDNA60w today. Was expecting the low ohm reading but mine reads the same as my boxer and ohm meter. I also have the new coil/same coil warning. Maybe they fixed the low reading, need to play around more to really know. Suprised about the excelent build quality and stiff 510 spring, puts my boxer with upgrated VT510 to shame.

wow 90 is pretty high. What temp you using with that (what atty also)??

cheers

450, it work great, not sure what it would do to dry wick though. I've run my tanks bone dry numerous time without dry hits though.

is that on a tank or a dripper??

Im using Ti with NP at around 45 or so - Ti TCR should be around 0.4 but here is no guarantee the NP and TCR are 1:1 correlated - probably not. Part of this is the low resistance reading issue I reckon but I have been running Ni at the default 70 and it works fine but I really think static resistance of the atty is a big deal in all this...

Where did you buy it and when was it shipped?

Maybe SXK fixed it - @TheBloke should know, but he´s bussy somewhere else :)
