Well said sir. I obviously need to invest in a printer, I think that may be my next purchase. After I get these next two mods built I think I will take the time to learn some new skills :)

 

Before you go investing in a printer, I would recommend checking out a printing service like 3Dhubs.com

Very inexpensive, I've printed quite a few enclosures in the past for other projects through them. Tons of suppliers on there so they are very competitive with prices generally costs me $15-$20 delivered AUD for a enclosure.

Fantastic service, I was considering purchasing a printer myself... but honestly I just wouldn't use it enough to justify the purchase.

Hope you don't mind another one jumping in!

I hope you don't mind if I get in on your thread? These are my first  250C builds I used  3D printed enclosures  from SW, evolv 510's & 4S 1500 mAH Lumenier  Lipo's  I didn't take a

Hope you don't mind me jumping in too, same mod as steamer861 I think (mine is sized for a maxamps 1300MaH 4S, but in black, used a Cisco v2 510 from Avidvaper.com so I had to shim it 1mm, lov ing rep

@gizman, I didn't find a battery by my prefered manufacturer to fit your bill.  My dislike for Maxamps came from my rc experience running my 15lb monster. 3 separate times I had Maxamps 4s lipos crap in less than a month, plus they couldn't deliver the amperage I needed from packs rated 3x what the max of my esc is.  SPC Racing was my brand of choice until they closed up shop, now turnigy seems to be the only packs that can reliably feed my beast and hold up for over a year.

It's a nitro revo converted to electric. Mamba xl extreme esc with datalogging, castle 1717 motor from XO-1, diffs from a losi xxl, and 1/4" keystock with impact wobble sockets for driveshaft.

I am sorry to hear you haven't had good luck with them.

Very impressive, good lord that thing is insane! I haven't been in it since the early 90s, my dad and I built some badass machines for what it was back then. Mad respect though, beautiful beast!

On 4s, with a phone inside for GPS speed, she'll do 62mph before she goes airborn. That's about 3/4 throttle.😎 she can pull 2 5yr olds in a wagon for an entire parade route on a single 5000mah 4s batt with power to play at the end

Sounds like getting some to help with (or just doing) some custom design work isn’t as difficult or expensive as I thought. I have been wanting to buy, build or get built a DNA75 (or perhaps now a 75C) Single 26650 Tube Mod but have had no luck finding anything remotely like it. I was looking at trying to buy an existing SS  VV or VW MOD which already had cutouts of a similar size but even finding one of those has been difficult. There was one released a couple of years ago (Can’t remember it’s name or the maker, some Chinese mob I’d never heard of I think) but I can’t find anyone who still has one...perhaps I’d be better looking at getting one designed &  “Printed”?

Hey Bud

If you are looking for a kit to build a 75c? Here a pretty good deal, you can get every thing you need in one kit :) http://analogboxmods.ca/Box-Mod-Kits/DNA75-Kit

You have several options, I build an ABM1 with a FD 510, a ABM battery sled & external chip mount. It's a nice small sized box that fits a 21700 battery. 

Here's a few pics of mine :) Thats a Hana Mod DNA200 beside it for scale :)

You can Email Them with Questions before you order, if you need Help  Dan even has some nice YT videos to Help along the way :)

Here'a another one :)

ABM2, 1000mAH 4S lipo, Sorce 510. 

I posted some reference pics, thats a  Silo 950 same size as the old Evolv Reference Mod 

FYI ABM = Analog  Box Mods

What’s the battery life like with this battery?

Hi

It's 14.8 watt hours :)  Compare this to 10.5 watt hours with a FullyMax 950.

It's  pretty good :)  I would say equivalent to dual 18650's,  :)

Assuming 2600MaH dual 18650's, you would be looking at ~18.7 watt hours, 3000MaH dual 18650's would be roughly 21.6 watt hours, if you could find a 1300MaH 4S that would fit it would give you about 19.2 watt hours which would be a closer comparison, or an 1800 3S would be about 20 watt hours.  The 1000MaH 4S I ran for about a month would sometimes need charged by the time I got home from work, for me and my habits anyways, the 1300MaH 4S and the 1800MaH 3S both pretty much get me all day with a full charge in the morning, just like dual 18650's used to.

I understand the numbers :)  It seems to me that a good 18650 (VTC5) would give as good or better Watt Hour rate as a Fully Max 950.

But in reality, with low ohm high watt vaping like I do, the Fully Max gives Me better performance & run time.

I find the same thing with the 4S 1000mAH lipo in my 250c. With my Vaping style the 4S 1000mAH will give me approximately the same run time as dual 18650's, even if the numbers would say different  :)

Funny, I was going to say basically the same thing, that at over 75 watts or so I get much better than what the numbers say I should with a 3S or 4S lipo than I ever got at that wattage, even running VTC6's.  Ironic that sometimes numbers DO lie :)

My go at building a 250C......

Materials:

Alpinetech 1590B with pre-cutouts 

DNA 250C Board Cradle

12mm Domed Tactile Switch

Varitube V1 22mm 510

Infinity 4S 1500mah 90c Lipo

14awg Output silicone wires.

28awg enamel magnet wire (fire switch wiring)

Waiting on a 6mm 3D printed spacer, from the UK, for between the lid and box . It’s a big a$$ lipo.....

How’s the battery life so far on that lipo?

@kwfranklin88 The mileage with a fully charged lipo is as expected for a 4s 1500 mAh lipo, not as long as you'd think with a lipo that size but my main reason for getting such a high C discharge rated lipo was so i wasn't stressing the lipo, regardless of my set wattage.  I'm sacrificing vape time for a higher discharge. There's barely any voltage sag even at a 300w preheat. I figured overkill on the lipo so i never have to replace it.

For those of you's who may be looking to build a more pocket friendly sized, lipo powered  250c mod.

This may be a solution for you :)

I built this mod with a silo75c enclosure  https://www.protovapor.com/product/silo-dna-75c-billet-aluminum-dna-mod-case/ a source 510 & a FullyMax 950mAH lipo. 

This enclosure was intended for a 75c! So with out some internal modification a 250c will NOT! fit.

The main issue is the space for the chip, as the 250c is 2mm wider. The button fitment & usb fit perfectly, once you remove the extra material for the chip to fit in place.

I used a dremel, & it was a lot of work! If some one has access to a milling machine it would be a piece of cake :)

Also note, space management gave me a choice of a better quality 510 (source) or an xt30 connector. I choose the live battery connection & the better 510.

If how ever you would choose a Varitube 510, there would be adequate room for an xt30 battery connector :)

See size comparison to a Silo 950, older dna 250, but same size battery

Went the shape way route, fit like a glove. Max Amp changed their battery size and it still fits. A bit too snug for my preference but with a 4S I don't think I'll have to worry too much if the battery puffs. My soldering skills on the other hand are a bit rusty.
