My SMY SDNA75 lives an even a tougher life than Chunky's although in a different way, I gave mine to my wife and it still works. She takes chain vaping to a whole other level. On the serious side I noticed no difference between 75/200 as I only vape at 45/35 watts.

There are connections on the 200/250 board for connecting LED's. They are not configurable through EScribe. One option would be remove/snip them.

In the lower right hand corner of Device Monitor in EScribe there is the "Diagnostics" tab, there you will find "Reset USB current limit".

That's it, it's done once you hit OK, it's real fast.

Explain "off", do you mean it switches from TC to power mode?

From left to right 3,2,1, ground

I used this one in my Vapecige VTbox200, it appears to be the same case. The power wires needed to be shortened and I had to change the plug to a "T" plug. Later Vapecige boxes use a XT-60 plug. https://hobbyking.com/en_us/turnigy-nano-tech-1300mah-3s-25-50c-lipo-pack.html

The screens most likely are made by two different manufacturers. Evolv doesn't make them. The brightness can be adjusted in EScribe.

Just change the watt hours to reflect the number of cells.

3 pin, how about a 4 pin?

From Kesters web site: (copied and pasted) 951 Soldering FluxKester 951 is a zero-halogen, non-rosin flux designed for wave soldering, conventional and surface mount circuit board assemblies. The extremely low solids content (2.0%) and nature of the activator system results in practically no residue left on the assembly after soldering. Boards are dry and cosmetically clean as they exit the wave solder machine. There are no residues to interfere with electrical testing. 951 exhibits improved soldering performance to minimize solder bridges (shorts) and excessive solder defects. This flux is suitable for automotive, computer, telecommunications and other applications where reliability considerations are critical. The surface insulation resistance on soldered boards is higher than that provided by typical water-soluble fluxes. 951 contains a corrosion inhibitor such that no corrosion products are formed when bare copper surfaces are exposed to humid environments. (it looks like water)

For the DNA250 the default (and maximum) is 28 amps for both battery input settings.

Thanks

Here's my question, will it light up the screen by USB power only.....just curious?

When one of mine was doing that it was because I had juice trapped between the balance connector and board.

Best I can tell, just checked a few of mine, is that it still doesn't function properly. EScribe 1.2 SP5.2 on my computer has firmware for 200/250 dated 12-22-2016. Still shows "?"

Have you tried rebooting the device? Either by removing battery or through Escribe?

16.65 watt hours with soft cell cutoff of 3.09 volts and the latest recommended firmware should get you back in order. Battery type: Lithium Polymer, 3 cell

Yes you can flash to older firmware. If it's not within your Escribe you may have to install an older version of Escribe to get the older firmware. I'm not thinking it will change anything charging wise but can't hurt to try.

The maximum charge (amperage) with a 200 connected with a data path shouldn't exceed 0.5 amps. Something wrong with the board in my opinion.

Rotating the cells of the pack when in a series serves no purpose like it would if they were in a parallel, if they work best in a particular order you might consider installing them that way every time.

If you feel like affixing a jumper wire from the output and ground for the 510 on the board and use atomizer analyzer in Escribe that will narrow down to whether it's a problem with the board or not. Kind of extreme perhaps but effective.

Well I think I missed part of your post, how about how well the body of the 510 grounds to the case....any oxidation?
