    Hi everyone. Coming here from ES forum. I have my new product done and would like to offer it as it might be of relevance to some skateboard builders. If mods feel this is inappropriate, please remove at will. Here is some introductory reading:

    As some of you know I have been working on solder-less, weld-less design for some time, well, nearly three years with on’s and off’s, ups and downs. Recently I have finished my fourth prototype and done tests to ensure proper battery operation. The tests came out very good but I was starting to get frustrated on managing production of all the bits, logistics, purchasing bits and bobs and steps necessary to get it delivered. This all work for a single line of battery, 14S6P which would satisfy a small part of people further cut down by limited power output of 2000W.
    Funny enough, after so much time spent on this design I had some eureka moment and went back to the drawing board. Now I can present my own, AMtech 18650 cell module with SNATHtech inside. I had to give it a name, N ew E ighteen S ixfifty E ncosure, NESE :).

    Here we have a lineup of four modules for 3 to 6 cells in parallel. So, what’s good about that?
    you don’t have to solder or weld cells anymore, that’s the key;
    you can repair it on the fly;
    your amp draw is theoretically limited by cell discharge power capacity.
    Other points include: assembly using minimal tools (scredrivers), reusable hardware; replaceable enclosure.


    I have thought of an idea to make it even better. The enclosure was designed so it was easily printable with today’s FDM technology, furthermore, because of this method of manufacturing, it was made light, yet stiff and it’s impossible to do with traditional processes, but that’s just a small part of the equation. Here it goes: i am selling all the copper/steel hardware and intellectual property. What this means, is I will be supplying all the bits that go inside the box and file that you will be printing your enclosures from on your 3D printer. If you don’t have one, perhaps a relative or friend will print them for you or in school, or in library, or through 3Dhubs and the likes. This brings several benefits.
    Manufacturing cost goes way down, including logistics involved;
    Shipping costs go down significally. I am talking 60% cut;
    If it breaks, you print another one, no shipping cost again and it’s local;
    You choose your color;
    You choose the type of plastic to use;
    We don’t do wasteful manufacturing where a lot of material is sculpted down, we use precisely as much material as we need by using additive decentralized manufacturing. This one fits nicely with ES spirit ;)


    Also, you pay someone who’s in your country so part of the payment stays within your country and you support local guys as well. It’s a small game but never the less.
    I will not bore you with tech stuff that I did on testing this method, you can find threads by me and Mr. Snath and find all relevant information there.
    So here’s what you can do. You can build yourself a battery out of 18650 cells without buying different bits from China like nickel strip (and then finding out its magnetic :) ), Plastic holders, spot welders, solder, iron, all that mess. You can build whatever SERIES combination you need and choose P combination that suits most out of four available, further more you can increase P by doubling or tripling or etc. You can make it waterproof by using plastics like ABS or polycarbonate and welding the lid on with common materials like acetone(to weld ABS), silicone(to seal the terminals), methylene chloride(to weld polycarbonate). Take precautions with later stuff!!!

    What’s in the box? Per one module, you get 2 x nickel plated copper tabs, one bare, one with SNATHtech. 2 x M5 nuts, 2 x M5 screw, 2 x M3 screws and chosen P printable design file. I could even arrange printable parts to be printed in your area if you are too lazy :).
    I hope you will like this new approach in battery building, different take on manufacturing and encourage sustainable fabrication. I trust community here will not judge me or think that they are purchasing couple bolts and nuts, but rather a concept that I have spent countless hours and large funds to get where it is now and improve it in time that will come.
    I am setting up a website to place orders without going through forums at 18650.lt – 18650 but at the moment, it will be available through paypal at agniusmk@gmail.com.
    I would like to offer first five sets (minus printed parts, shipping and up to 14S) for people who can do unbiased video review. Forward payment and after video review is up and posted here, get full refund.

    Any questions, please do not hesitate to ask!


    So that’s that of my shoulders, if you have any questions please ask, would like the discussion started with good’s and bad’s. I don’t have final pricing yet.
    Cheers, Agnius

    I now have a functional website at http://www.18650.lt
    I would like to clarify pricing to avoid misunderstanding. It is a big price to pay for couple of bolts and bus bars but i include my cost of the development of the product, paypal fees, expenses involved with packaging products for shipment, website support and my cut. I have all my 3d models available to download and the work on them is also calculated into the price.
    Basically the cost of 10S6P battery would end up being ~150EUR + cells.

    Thanks for looking and reading

    P.S. I would hardly recommend to visit blog section on the website. It has some videos in regards to making these modules and testing them

    This looks like a really cool idea, but on of the things that makes Evolve batteries struggle, and is challenging to 3rd party replacement batteries, is how thin the enclosures are. Any dimensions for width and thickness of a built pack? (if that's listed on the site, sorry. . . I'm unable to access it from a work computer)

    Looks like it could be great for a top mount battery on a off road mountain board though.

    Thank you. The dimensions are on the website along with 3d models and thech sheets. Its a DIY module and strongest aspect is that you don't need to solder or weld it. Regarding evolve board it all depends. I see they are 36V su putting largest 6P module would be out of the question cause it will make it 740mm long. 6P module size is 22x74x123. That's up to 20AH pack at 10S, 36V nominal. Now if you would take 3p module, that's up to probably 10AH, it would make it 370mm long and 150mm wide, 22mm in height. Its not most compact but its very friendly to inexperienced diy'er. It also has most punch out of 18650. I tested it at 120A continues and cells were limiting factor.

    I think the Gen2 Carbon box is something like 15x142x615. I think the case on my G2 Bamboo is 15x133x330mm. I'm not sure about the GT series boards. The 15mm height is relatively easy to increase to accommodate 22mm, but I'm not sure about the width.

    Wish I were available to do some fiddling and measuring, but unfortunately, it'll probably be a month at least still before I can even get mail. Sounds like it might be an upcoming project for me though.

    ps: totally ganked this picture (and a lot of info) from whitepony's thread here: Endless-sphere.com • View topic - Evolve Carbon AT with 50km+ range
