Seen people like looks, I don't get it, looks like a old fashioned portable radio!

Billetbox looks, twice the power, probably too much power from an 18650 without the type of monitoring and control you get from a DNA, shame they are not using the sx350 as it seems a lot better board IMO.

Not sure it's a good idea using a 18650 with 100watts is it?

The sx330 won't downregulate, no biggy to me, but curious about other negatives? Build quality?

I will stick with the DNA for a while, though John Evolv's designer said something alone the lines that the SX boards were alright (IIRC near the end of the pBasardo factory tour part 2), but I like how the DNA monitors battery sag and load and I don't think YiHi do nearly as much in that area.  I wait a few months and maybe build a small SX350 mod.

The dna tests ohms whilst firing and regulates the volts to keep wattage same, whereas sx330 just tests ohms at start and outputs same voltage till button released, at least that's what I got from pBasardos review.

Is that a problem?

That link doesn't seem to work for me VapingBad, at least on my phone.

Curious about all this stuff, fully admit I don't know as much as I'd like about it.

Night bud, sleep calling.

Could be if you melt an insulator, pop a coil or the heat makes poor connections tighter with thermal expansion and that suddenly lowers the resistance. The DNA may regulate power dynamically by voltage and current without testing the ohms at all while firing.

ah...that doesn't sound good.

Would just hope that wasn't the battery that went boom in this case.

Would be good if someone was willing to test what happens if dead shorts whilst already firing to confirm if it does go boom.....any volunteers

Wonder if sx350 chip would fit the IPV case if sx330 chip went pop.

If it is a problem then it will happen to someone...hopefully not me!

I've had coils pop before in protanks, but they just lost connection.

Did have a short happen in fatty v3, was because I'd put it together wrong, showed ohms when testing but then shorted.... I'm going to be very careful with this!

Twisted wire I've had change resistance a bit so maybe avoid that too, no need to hunt lower resistance with this thing anyhow.

[VapingBad]

I don't think that is anything to worry about just be aware of, a little like the difference between anti-lock breaks and ordinary ones they both work but ABS eases off the pressure if a wheel is about to lock. I don't think popping a coil would cause a problem.

At the weekend I built a coil in another members Kayfun clone, it was the expected resistance until I put the cap on the chimney when it shorted. On inspection they had socket head screws on the coil and the +ve one was shorting on the chimney cap, they said that the short didn't always happen. Strange things can cause a prob with heat the screw may expand and cause a short where it was OK when cool.

Just to confirm, so if I get a short mid firing it is likely to break board at very least though?

I don't know, but from the video it seems very possible if it was a short that would take over 50 W, maybe the board can handle over 100 W, maybe the board is protected and will cut out when things get to extreme we just get snippets of info and are trying to complete a jigsaw with only half the pieces.

Thinking about it I don't know how happy I would be with my ADV which is dual steel rope Kraken as if the rope touched the centre post while firing that could take a lot of power, but maybe there is a fail-safe in there.
