The 200 has separate Atty Lock and Power Lock settings. With profiles, Atty lock becomes useful if you need to switch between coils while hot.

Difficult. Not impossible.

It didn't offer to retry?

Linux on the desktop is not even an asterisk's worth of marketshare. Will we do a Mac version? Yes. Will we do it by a programmer employed by Evolv, in house? Yes. If you feel that smok makes a better product or has a better direction, feel free to go buy their configurable 200w product. If you feel smugly assured that there will be a clone product eventually, I agree there probably will. Feel free to buy that. Let me know how that goes. Or don't let me know. We aren't doing a Linux port and we aren't interested in volunteers programming.

Yes, and to have any low voltage cutoff. The taps are not optional.

Oh... That is an interesting question. Room and board temperature are internal prooperties. I'm not sure those can get converted to C right now. Worth adding if not.

Asking questions is what this forum is for. Where do you want to show Celsius? It should be available everywhere you can show a temperature, but how you set it varies by item.

If you want to come work for us here in Ohio, send us a resume. We are always looking to hire truly superior talent. We are not interested in having ports done out of house on a volunteer basis. It is too big a project for that to remain workable long-term.

You are free to trust or not trust whatever you like, but what exactly are your concerns with charging the 18650s from the board? It is very much built to handle it.

Just as safe if the 18650s are tapped and polarized properly in their connections. Lipo and high drain 18650s charge exactly the same.

Make sure you have both the power leads and the tap leads connected before you start charging! Otherwise yes, set up the proper settings in Escribe and you are good to go.

You can change the max output power on the research tab. Under power select "locked" and enter a smaller range.

To elaborate a little on this, DNA 200 is the base product. DNA 200D is a configuration (standard board, with standard screen) If you were a larger manufacturer that assembled your mods in china, you would probably order them without screens (no reason to import them to the US to re-export them back to China) and that would be a DNA200. If you got them with different switches that would be a different order code. They are all DNA 200s though.

We'd be happy to host them if the wire manufacturers send them to us, but I imagine they'll put them on their own sites with the wire.

Has to be 3s Using LiFe the max output voltage and the battery cutoff are lower.

The portion with the battery meter paints on top of the image, unless you have it selected to do otherwise. Make the screens as you like, and then leave space for the battery meter if you want to display the battery display on top.

The board itself really shouldn't require ventilation if you have a decent thermal conduction path from the board to a metal case. Even in a plastic case, the DNA 200 at a pretty typical 100 watts and 30 amps generates less heat than the DNA 40 did at 40 watts and 18 amps. That said, the board is conformal coated, and all the switches are waterproof and dustproof. Dripping or condensing moisture won't hurt it. Conductive dust could cause a problem with the pads for remote buttons, but non-conductive dust isn't going to hurt it. My biggest area of concern would be the USB connector.

There is a new Escribe (V1.0.20) and Firmware (6/30). Escribe will offer to update the next time you run it. Once you have the updated and run the new Escribe, there will be a message offering to update the firmware on your DNA 200 the next time you plug it in. No major features were added in this round. We made small tweaks to the Production Utility to allow it to be used to mass update bare boards, as well as complete devices. Other minor bug and graphical fixes. We added an optional message screen if the user is hitting the max kanthal power. On the firmware side, we fixed a few bugs that would have made the device consume power while sleeping if the setting file was corrupt, fixed the blinking screen when the balancer is disconnected for Power Supply mode, the device recovers correctly from a balancer disconnection, and stops charging if the balancer is disconnected during operation. We added the option to charge to 4.1 instead of 4.2 volts, which improves the number of charge cycles a battery is good for, at a cost of runtime per charge.

The new update that just went up should fix the blinking in power supply mode. Let me know if you run into any problems with it.

Well, we don't plan on making DNA 200 mods. We do plan on making parts for DNA 200 mods.

The issue is really more at low battery than at nominal voltage, so the math goes 23A * 9.1 = 214W 214W/(3.0*2) = 35.7A And I agree 100% there are few realistic continuous 35A 18650 cells. There are ones that can do it as a parlour trick, but not all day every day.

Is that a rumor? I thought we'd been pretty open about that plan. But we have zero full time machinists right now, and while I can run the machines for prototyping and betas, I can't realistically make money if I'm machining cases in production rather than working on electrical designs.

You can certainly vape while connected to a USB charger. It turns the charging off while you are firing, and for about 5 seconds afterwards, so it won't stress the battery or the USB port to do so.

When we were assembling them we would have them electrically complete, including the output connection on an insulator angled above the case. Then gross position the board into the case, remove the insulator (really just a piece of cardstock) and then be really careful. If there was more space, using a power connector would have made the process faster, and if we ever went into production we would use a connector. The plan is for individually insulated short 2mm bullets.
