I've rewired a Fullymax 3S 900mah, into a 3p...probably the smallest package I could come across with 3 in parallel. Their pack assembly actually made it fairly easy to breakdown and rewire - no circuit board at all, but I would advise using some adhesive solvent and a thin piece of wire to separate each cell to flip it for proper orientation.

Sure you're not just hitting amperage limits on these batteries? 18650's sag considerably more under load than lipo. 25r's are basically a 20amp battery right, and doesn't the 75 pull about 26amps under max load?

thanks, Nick.

So Nick you mention putting a female charging port in the bottom of one of your personal mods. would you anticipate any issues with have a parallel JST connection, one from battery to DNA board and the other to an external port - to use an external lipo charger?

I would think 3.4 ohms is pretty high, could you make a similar and put the two in parallel?

The case analyzer will help with this. Each chassis has different thermal properties, the only way to get this thermal offset is with case analyzer. it's kind of shocking that these large mod makers aren't customizing this prior to sale.

Thanks guys!

I see one mention of refinement on the DNA200 spec sheet in the resistance lock session, and various mentions of the term on ECF and here. When exactly does it take place - during run time, soft / hard reboot, while powered off? What exactly is refinement? - I know this sounds like a dumb question I'm not really seeing much fluctuation in resistance, maybe a .14 build I will see change over the course of the day to .15. I'm guessing this is just a rounding of the thousandths digit.

Any of the modders here have experience with these? http://www.electronicstix.com/products/z2-2-510-connector-obsidian-zenkote Obviously it requires a screwdriver for adjustment, but I'm curious if it would be a bit more solid connection than a Varitube 510. I'm thinking my spring is compressing a bit, and without buying 20 wave springs....not sure where else to go. If only we could get Evolv's 510

I've not taken my 200 past 60 watts yet, stay in the 20-30 range. Mainly build for flavor, but it's nice to know my mod has much more headroom if I choose to use it. Using a 3d print copy of the reference case with the fullymax 900mah battery, I'm easily getting two days out of use. I've also got a mod that's extremely pocketable, with a great chipset behind it. I can't say that about the 100's of budget mod's flooding in from China.. Not saying a 1S variant is useless, but maybe I only use my 3s like a 1s

fuse data sheet from mouser: http://www.mouser.com/ds/2/358/typ_UST_1206-245456.pdf 3413.0332.22 is the pn listed in the DNA 200 data sheet -the final .22 is ordering in 1000pc blister reel. The .0332 would be the 25a variant, this fuse package is sold in 7a through 25a types - with these 4 digits varying by rating Just to confirm, searching http://www.schurter.ch/ by pn 3413.0332.22 returns the same UST 1206 print that is referenced in the mouser link. ( http://www.schurter.ch/content/search?SearchText=3413.0332.22&tab=section-2&filter[]=attr_subcategory_facetata&filter[]=language_code:ger-DE ) I'd say your good to go

By the manufacturers pn that should be the same fuse listed in the dna200 data sheet.

I'd like to see this as well, or at least a way to tag a profile as temp protect or Kanthal - so you could not see a temp on the kanthal screen

There wattage should throttle down as you hit temp protect target, but I've not seen mine go to 0...like it was said before hot legs, odd coil connection, etc

Could you share a shot of device manager with you firing? Is your non firing resistance fluctuating?

This may sound too simple, but have you tested removing escribe and reinstalling as admin? I had a similar error after installing the 8/6 rc over the previous version.

Thanks, John. Actually I assumed it was only the two test states, first setting base temperature and then charging. You say there are 3 charge states, the roughly two hours of data wouldn't be enough. Time to run this on a stand alone pc outside of our network environment!

I agree xevape, heating the whole pca isn't ideal. That removal alloy stays fluid for 6 seconds or so, so it theory I could rotate heating all four contacts with an iron and remove by suction on top. With a lower melting point, it could allow you to use less heat/application time and hopefully doing this would eliminate the chance of melting a pad free... Simply posting this as an alternative, not trying to take anything from your approach! Great looking mods by the way. Are you pca's adhered to the chassis by the tactile buttons? Is this why you are testing applied pressure?

Would you guys think it would be feasible to flow some chip quick alloy onto these button pads and use an IR board heating station to get these loose? Chip quick would lower the melting point to 100-200C, and most board heaters I think tap out at around 250C. I've done similar to remove large flat packs.....~200 legs.

The orange buttons are already showing signs of color rub from the black. I may eventually paint them. You may notice I mounted my +/- backwards...luckily escribe has the ability to swap function! The same creator on shapeways lists only the chassis without buttons and buttons as a 3 piece for a few bucks. I am liking the form factor in hand, but it just feels very light coming from using an aluminum mod before.

Finally have left my enclosure closed for a couple days, this 3d print copy of the reference case has very little room for error in depth. The side walls of the back chassis snugly hold this fullymax 900, so it isn't likely to be jostled....although i'm not sure of the shock absorption rate of abs. Many attempts at filing down the +/- buttons to not actuate when the back was screwed down. I ended up tossing out my xt30 connector and soldering the fullymax directly to the board. JST connector is still used for the taps. Considering 3d print plastic likely will not take well to repeated screw fittings, I don't plan on battery swaps!! Once someone gets the aluminum reference boxes up, I'm jumping in line to purchase. Definitely not as refined as several that have been posted, but my first foray into a mod this small.... case: https://www.shapeways.com/product/6524725AS/evolv-dna200-case-with-buttons?li=search-results-1&optionId=57294605

Evolv clearly stated in the 200 datasheet wire Gauge usage and peak current... Modders should be able to find appropriately rated power connectors or solder the battery to the board. The screw posts are also clearly labeled as ground plane, so a modder assembling with a conductive fitting that overlaps onto a solder plane or via is just sloppy in my opinion.

Have you set your mod resistance? Using an atomizer with a copper short between neg and pos, you should be able to go into Atomizer Analyzer and it will give a reading of your mods resistance. Power mode will compensate for whatever internal resistance (short answer), but temp control at such a low resistance can be thrown off when your mods resistance is 0.005...or whatever it is. My 0.005 was generated from an old ego to 510 adapter that i've solder shorted. After typing this into mod resistance, device monitor will now show a different cold resistance than live resistance (with a kanthal coil attached).

Is there any way to upload a partial case analyzer csv, or at least the formulas used to derive the time constants and case usb charge fields? My pc freakin went to sleep with 30 secs left on the second hour (charge cycle)

Could that batt + solder use a bit of work?
