    Just hemp

    What Tibs said....and yes oxyclean is used for laundry. Don't use the thread from hobby lobby, I tried it and no bueno. Get the thread from etsy that BJ linked. I don't really pack the side pieces, I just set them on top.

    Battery Question Dna Device

    I have tested single and dual Sony VTC4 and LG HE2, both work single (with a good low resistance connection to the DNA) as well as dual.

    DNA 30 battery voltage issue

    I actually talked to Evolv and directed them to this thread. They said based on the info provided that it sounded like a bad board.

    DNA 30 battery voltage issue

    The DNA needs to see a load to output, so an atty needs to be hooked up. Then you can use a dmm somewhere on the output +/- and see what it reads while firing. Just curious....what ohm coil are you using?

    DNA 30 battery voltage issue

    Then I would say something is likely off on the output or the atty/coil causing the ohm to change. But you should see the ohm change on the DNA screen as well. Hmm.....weird....

    DNA 30 battery voltage issue

    Is the DNA showing 3.2v when the fire button is pressed? Or are you measuring voltage somewhere else?

    Battery Question Dna Device

    DNA30 at 30 watts needs a battery capable of constant 12amp discharge. The c-rating of a lipo is only half the equation....c-rating x battery amp hours = constant amp discharge rating.....2000mAh = 2Ah x 20c = 40amp constant discharge rating. C-rating has nothing to do with the charger as far...

    Picture of Your Setup Part 2!

    Self made (3D printed) DNA30 18650 side by side mod.....I call it the bap SxS. Still unfinished....I got in a hurry and made a delrin button....need to make a ss button.

    Raptor Flip-Top VV Mod with 20A, 120W dc/dc converter...

    BJ I almost forgot.....but I remembered :D Housing for 0.28" digit volt meter - https://www.shapeways.com/model/1736356/volt-meter-housing-0-28-quot-digit.html

    The "WeekEnder"

    That is a tough size, any lipo that size will likely be less mah than a good 18650. You can check out Hobby King but I bet most flat cells will be wider than 30mm, I will try to remember to measure some when I get home. Hobby King has some 800/900/1000/1200mah round lipos that would probably...

    Wow!!! Check out the fuse I just found!!! 7amp 0.001-0.007Ω 2920L700SLPR

    I have a fuse question.

    I just found a 7amp fuse with super low resistance that I'm going to order - 2920L700SLPR

    The "WeekEnder"

    So to go along with some of the resistance testing.....see below for what I noticed on my SxS mod. I have been doing some resistance measuring and etc. and I was planning on using an Origin mech ss battery tube for the inner battery tube, but I picked up some Copper 122-H04 Hard Drawn tubing...

    I have a fuse question.

    The right fuse or fuses for you is going to depend on you, your enclosure, etc. For a DNA 30 you want a fuse(s) for 12 amps or close to it. If you use a PTC resettable fuse you want to go off the hold spec. Using two fuses in parallel reduces the resistance imparted by half. So I recommend...

    dna 30, dna 20, Groove, or zmax PCB board to make my mod?

    Evolv has the DNA30 data sheet on their website and it covers most of your questions
