Mod build planning- Circuit options

[Dougiestyle]

I'm in the final stages of R&D of a 26650 bottomfeed in the Zero style. Sourcing some circuits in the raw is not easy, so my plan is to dissect a mod for the chip. Looking at FT, I've come to these two options for form and function:

A) $40.87 MODZ Pack D-NA 50 Mod - 7W-50W / 1*18650 / red at FastTech - Worldwide Free Shipping

B) $39.80 Smowell DPV-50 Variable Wattage VW APV Box Mod - 6.0-50W / 1*18650 / silver at FastTech - Worldwide Free Shipping

Option B is more affordable, and is rumored to be the same circuit as the smok M50, and option A is the ChiDNA. The Smok/Smowell circuit is one long board with fixed tactiles, and the ChiDNA obviously has modular switches. The long stick circuit does not bother me, as the orientation fits the design I'm going for, but I can accomodate the modular switches to a similar orientation.

Questions are:

Pros v Cons of either/both chips as user and/or modder experienced?

Any sources available for either chip that are even more affordable or comparable, stateside (US)?

I'm an experienced modder, so no need to tip-toe with concerns

TIA for your opinions!

You do know fasttech sell mod chips not in an enclosure?

The dna style 20's and 30's
Vamo and MMT boards up to 55w

Cheap, less than 16 bucks some are 7 bucks.. Good reviews to..

This Vamo board has stellar reviews. Seems much better than the 55W chip. $15.11 Vamo V8 3.0-40W VW Variable Wattage Control Module at FastTech - Worldwide Free Shipping

Wow! Thanks for the suggestions thus far! I guess I should have mentioned that ideally, I'm leaning to the narrow display like the DNA, but 50W or better.

 

[Dougiestyle]

is it possible to source the Yihi SX300 (not350)? I thought I saw that it's proprietary. I know the SX350 can be purchased @ varitube, but trying to keep circuit cost under $50, and I'm not out for wattage above 50W.

Another note would be sub-ohm capable. The Vamo V10 looks to be spec'd @1ohm+. Some varied reports of 0.3ohm, but conflicting opinions on that issue.

The fasttech init is limited to .8Ω but if you can source someone who sells the mmt boards you can buy the 55w board that does .3Ω. I have not seen it for sale but its out there.

Check out the MMt boards scroll down to middle of the page..

I also wouldn't mind a MMt 55w board but the MMt M352a is the one I would've jumped on.. Not the MMt M345a that fasttech sells..
Hopefully fasttech will get the M352a in...

That 40w board at fasttech is solid many good reviews.

But its a new day for us OKR builders
If you don't mind building from the ground up get an OKRt10 build going, its a barebones 60w module but it will do over 100w and Mamu just posted a display for it..
Cost about the same; the okr is 8 bucks the display is 8 bucks then components about 3 bucks for me its almost a no brainer now with that display..

 

[Dougiestyle]

I actually have an OKR-T10. I may need to revisit it and Mamu's tutorials

ETA: Scratch the OKR-T 10. It's 7.4 series. I'm trying to build single 26650 w/boost controller.

Desire E-cig has a DNA style 50 VW module that might fit the bill. I just translated a French comment in the discussions/reviews about the wiring, and along with the pics on the site, it looks like a good option. I am considering it for replacing the module in my older DNA 30 clone.

 

[smaugmra]

The Desire E-cig has a DNA style 50 VW module does seem somewhat expensive when compared to the other DNA style modules available in a lesser VW rating.

I have gone completely over to the large screen DNA 40. Really love the chip and display. I have been getting them around $35.

I've seen some circuits cheap on Ebay but always check the sellers ratings and locations too.
