75's are all the same.

If you had a 0.08 ohm coil that you wanted to power at 50 watts the 75 will do that, I'm pretty sure the 60 would not. Or if you had a 1.0 ohm coil that you wanted to power at 50 watts the 60 will do that but not the 75.

I bought some 317L a few weeks ago so I could have some experience with the SS3xx but my SS430 works so good I just can't bring myself to change to it.

Did it charge OK prior to a couple of days ago?

I really don't have an answer but do have a couple of questions. Have you tried a different cable or perhaps a different power source? Edit: cable must be OK, it's reading the USB's voltage. Did you change the USB current from the "Diagnostics" tab in Device Monitor to zero by chance? Does the mod work?

It's in the bottom right corner of device monitor under the the Diagnostics tab. On the 200/250 you can set what you want (max), on the 75 you turn it on or off. The adjustment is made to the mod not EScribe (no upload required). Just remember to set it back when your done, it will use it's setting with a wall wart so if you left it turned off it will not charge.

Realistically your watt hours for those will be about 27 -28 Wh, keep in mind that the 200 was designed to use a lipo pack so you won't be taking those 18650s down to the 2.5 volts as that's what was done to achieve their 3000 mah rating. The hardware cutoff is 28.5 volts on the 200. I set my soft cell cut off to 2.9 volts when using 18650's in a 200.

Your batteries are near depleted, what batteries are they and what's your watt hours set to? Post a screen shot of device monitor showing your cell voltages.........after you charge them perhaps.

So I set out to test my SDNA75 with LG HD2 18650 with my Velocity @75 watts....I eventually gave up (at 34 drags) as it just isn't my thing but here are the screens at the start and my finish. It seemed to do quite well I thought. But the flashing battery icon was coming soon...@ 2.75 volts.

Probably better than average.

I paid $80 USD for mine, they list for double that. Sounds like a deal to me.

Here also, depending on shipping charges they may be a bit less than Amazon. http://www.ebay.com/itm/PortaPow-Specialised-3-3ft-20AWG-Charge-Only-Micro-USB-Cable-2-Pack-New-/282068762006?hash=item41ac9bbd96:g~oAAOSwepJXYQK7

I think quite a few of them have the screen off a bit, mine's not too bad but is crooked. I have 3 Bellus' and all of them screw flush as well as anything else I tried fit flush. By pushing in the 510 pin on the mod with a small rod does it seem to have the expected travel?

I left mine there. I think most did also.

Maximum voltage on a DNA200/250 using 2 cells is 6 volts (9 volts with 3 cells) On the DNA75 it is 6.2 volts DNA40 & 60 output to 9 volts

My thoughts on the reason for 316 being in demand more than 430: 316 is a higher grade used for medical equipment. 316 was being used with mechanical's early on as it is what was availible (welding wire) Just my opinion here. The resistance change between cold and hot coil is to be considered, the more change the easier for the board to work with it.

The version of EScribe that you were using is only for the DNA200's You will probably be looking for the mod tab, go to "Options" and "User Interface" and select "Manufacturer" from the drop down menu. Edit: made a correction

https://downloads.evolvapor.com/SetupES.exe Try this.

I guess that part really doesn't matter, my thoughts were something wet and gooey on the board like flux or juice conducting micro voltage from part a to part b, something along those lines.

Is this a factory built mod or did you build it?

What happens with an external charger?

rbtx is in Orange County, Ca.

This is the settings for Steve's Hcigar VT133. What DNA200 mod do you have?

Go to "Options" and select "user interface" then "manufacturer" from drop down menu.

If it were me I'd open a ticket with Evolv and explain everything. It can't cost that much more to send three as opposed to one. Nothing to lose really, if they tell you to send them they most likely will take care of it. https://helpdesk.evolvapor.com/index.php?a=add
