I have been waiting for a system like this for a while. Also truly appreciate the honesty and transparency. That made me even more interested in what you had to say.
Love these, built 2 4x12 packs. Amazing how simple and easily arrange in to limited space. Drone ground station runs forever on 200,000+ mah
really nice kit but insanely expensive unfortunatly
I just got my first couple of kits. This is perfect for guys who don't want to spot weld!! Thank you!
So happy you are so into this and others too to bring this idea to fruition. I have been running SLAs and aspire to Lithium Ion. But that is a lot of penny's to save for a pre-built battery. $100 compared to $600, that is a stretch I cannot make. Now I have an opportunity to build my own without welding, which of course requires a welder, again cost, or soldering. Plug and Play basically. Brilliant! I have a fighting chance! My ebike is my mode of transportation which is Fantastic. Winter gets a little rough and rain is unpleasant, but doable with the right gear. Your book, DIY Lithium Batteries: How to Build Your Own Battery Packs, is on it's way. I will definitely be buying the kit and possibly the 18650s from VRUZEND.com as well. I have learned my lesson on cheaping out on other things, so I will be sticking with a name brand battery. Thanks so much, enjoy your videos, very informative and it's lot's of fun to make your own stuff, and of course less expensive. Kudos, keep on keeping on!
Wow these are awesome! Just bought some and I gotta say, the price of $44 US, is just the right price. Thank you for this product!
One thing I think could greatly improve your product is if you would just make half of the connector tops black instead of white or clear. Then it would be really easy to spot your negative and positive ends and would make battery design so much more simple. Maybe you could implement this in your future production?
I was an early adopter of Vruzend. I've changed out the stainless steel 'bus bars' with copper. Much less heat but still more than I'd like. The 'spring/bolt' combo is also a pretty high resistance material but for what I'm doing 36v 10s 5p it works pretty well.
I'm still working on a box that I can quickly remove and replace the 18650s as taking the Vruzend system apart and building it again takes too much time. Still if you want an interchangeable battery pack this is the best one I've found.
They also sell a couple of pretty nice BMS if you want to wire them up and balance charge the cells. For me that's lost as I want to charge each battery individually.
Thanks for the vid
Thanks for your videos too! And good call on the copper bus bars. I've been doing that as well. We're also working on new spring terminals for higher current, so you should like that version even more, once it gets released!
EbikeSchool.com sounds like I might need . I'm far from wealthy but with age and disability electric bikes are really interesting me.I know there are a lot of variables but could you give me a ball park average of how much you save by building your own!?
EbikeSchool.com for those who purchasing kits now, how can we get updates. I have an account with Vruzen.
yea, i thought the steel bars were a bad idea all so (cheep) why not stamp a better contact metal?
this helped me a lot cause I am just learning I hope you will do one for 48volt 20ah battery pack too and also adding the bms to the 48 volt pack I realize it is just adding more cells but being able to watch you do it step by step helps big time and takes away any concerns weather you forgot something or just that you did it right I would really appreciate it anyway thanks for all you have done
Hi Micah: Your book on DIY LITHIUM BATTERIES was the bomb! Well written and super helpful for the beginner. I want to buy your gadget. I also used to live in your neck of the woods back in the late '80s. Cheers!
As a newbie to battery building this kit really makes it easy. A bit of a learning curve on connecting them but once you know the secret..easy peazy. The terminals for the wire contacts though could be beefier and a bit wider. 1 gauge doesn't quite fit IN the connector. The battery comes out less streamlined but it'll be worth it if you don't want to mess with soldering or welding.
I am not sure about the battery kit. Okay for prototyping small to medium power but the more power to be drawn out of a battery and in a shorter period of time could be a problem. A real time saver building a battery with this kit. Many have noted other problems so I will not go into them again. I will be buying the kit for quick prototyping projects. I bought your book when it came out. Thanks for the video and good luck with your venture. I hope it is a long time success.
I've been asking for a product like this for many years. I saw an Indian company stared selling them last year but they weren't spring loaded. I prefer the spring loaded version because it seems like it would be more reliable in making contact with the cells.
This kit in the video has spring contacts
Can you please tell me something about the Indian company
Great video! Always very helpful man keep it up. Appreciate all the links in the description too 👌
Great! It helps innovators on all rungs of the ladder. Bravo.
Great concept , you might even embed electronics in each to manage notification , and manage the cells when they become sick ..use colour plastic to identify pos and neg sides ..red and black tinted plastic .
pay this man
if ur a fool, indeed - do it
Nice to see you acknowledged my idea of coloured terminals in your new release ... Sarcasm
Red and black is a good idea
I want to let you know how much I like you sharing your knowledge about building batteries. I would like to see you build a battery that fits inside an aluminum bike battery case. Also your idea of the best alarms for ebikes.
Thanks for the great instructional video. I joined to learn and you are a good teacher.
This is a SWEET kit! I ordered mine today!
I definitely think you made the correct decision in supporting this project. Heck I wish I would have known because I would have tried to help them but I guess I'll help them by buying some now.
very helpful video,,iv watched so many of these due to interest,,yours is very easy to follow and glad the title mentions the name of the kit,,great job
I appreciate the transparency, cool !!
thats just awesome!
Great product and idea! Are you guys planing to make kit for high drain cells? Looking forward to that. Am planing to make 72V battery pack with 18650 20A cells. It would be great to NOT spot welder all 140/180 cells and make life little easier.
It's good knowing how to build a battery and have fun doing it saves you some money.i appreciate your how to battery building and charging videos.
Just what I was looking for. This is perfect because I want to built a 14.4 kW batterie unit for my reverse trike! :)
Great, this makes things much easier for people who do not have access to a welding machine and can create a battery pack as needed.
Awesome video... love those kit. Question, can I build battery banks for my rv solar system using this kit...like 4 100 amp hour...?
Love the bed head look Its going to be in style 2018-2019
It’s 2020 here, confirming that every single male is rocking this look.
So much information . This is so enrichment . Thank you
I can’t believe no one thought of this long ago ! Great
And another suggestion, for the BUS BARS, Suggest you make it not a STRAIGHT FLAT BUS BAR but rather a TAPERED BUS BAR or it is very thin at the middle portion, for what purpose? The thin portion will act as the FUSE WIRE, making it not only a BUS BAR PURPOSE but also has FUSE PURPOSE, a thin strip at the middle of those BUS BAR will burn, break or melt just in case 1 cell becomes defective and effectively shorts out.
Very cool!
You mentioned making odd shapes like a triangle. I can see how you’d do that physically, but how would you wire the busbars to preserve the electrical balance of the pack?
Great work, dude! Just what I need!
I like this - Great Idea -
things to add
also sell stamped copper buss bar in Rolls - then it could be cut to length needed -
Looks like pack would be hard to take apart because of tight fit - is it ??
just purchased your Ebooks to support your efforts. Thanks
Liked how u were honest from the gate.. 👍
Hi! Excellent video! It would be lovely if you had a summer school work shop on how to build a complete ebike!.... It would be an awesome one or two week holiday!!
Great system design. Looking to replace my Lead Acid batteries on my 36v scooter 10Ah. Looking forward to your next video on installing BMS to your 10S pack. Do you solder leads to batteries or crimp wire knuts and then bolt to battery terminals tops?
Ha, had this idea 2 years ago, to 3D Print a system like this that would all interlock to assemble into any size and eliminate soldering! Finally somebody did it!
Brilliant invention! Can't wait to build mine!
I'm going to be building a battery to power an electric motor for my (large and stable) ocean kayak. I plan to put the batteries in a water tight container with desiccant packs inside to absorb moister, however, I've found that no matter what you do in water environments, moister creeps in and corrosion sets in. In the past I've used dielectric grease to stave off oxidation on electrical connections. I was thinking about using a very small amount to coat the connections when using this kit.
Can anyone think of a reason that would or would not be a good idea?
Best li battery pack I av watch so far
I bought two of these kids I can't wait to try them out.
I like u r videos Mike . I learn so many things from u r videos . and I waiting for u r next video to add bms to the kit
Great idea! Congrats!
Fantastic product. Will try find it here in South Africa
wow thats pretty cool, nice implementation, though they will have higher resistance than spotwelding. however for the sake of reusability/repair and ease of building that is a good trade off for a few milliohms.
I have the kit, it's pretty amazing!
Is it much cheaper to build your own?
Superbe taf propre pour les Trottinettes electrique etc...bonne idée Merçi bonne continuation cordialement Michaël
I like the concept, I found another printed option close to this design as Battery Blox using magnets and bolts to close the contacts.
Can you please tell me more about the printed option. Name or some link would work. Thanks.
@@therishabbakshi Take a look at @Shawn McCarty on youtube he has a really solid design too .
@@therishabbakshi Oh and try the application from the google play store "Battery Package Calculator" works for calc all your design battery 🔋 needs to tell you what power and what shape decisions you can build and how to set up your parallel and series connections as well as power consumption.😉 Or go get Micha''s Books 📚 Thanks Again for all the info on this channel for my builds has been invaluable information !
Wow that is an awesome kit Mika thank you 🤙🇨🇦
Once pack is assembled use wood blocks with bolts to keep the compression from decompression only true way to be 100% certain contacts between each cell will stay tight
Omg this is so amazing. This is life changing. I'm going to buy so many of these thank you so so much.
George Knowles loool.
hey man let me know how it worked out
I really like the honesty two big thumbs up
Two things that caught my eye as you where working. When checking for a connection with a multimeter add a load, a small load will work. If there was a 1000 ohms resistant in your connection it would show good in your voltage test. It would be like a open circuit if tested with a load. Pushing the batteries in with your bare hand. The acid on your skin could affect the battery connection over time. I like your kit, I think it will get many more people into making there own batteries.
These are both excellent points, thank you. And I meant to mention that latex or mechanics gloves would be good to avoid leaving oil from your skin on the contact. That oil can slightly increase resistance, which makes waste heat.
I've soldered tags to CR2042 cells. Being thin have to be careful. I tinned the surface with solder then was able to attach the (tinned) copper (or brass) tags with just enough heat. Not everyone will like the idea but it does solve the issue of mechanical loading.
Yeaaahh... I have 2x VRUZEND kits here!! The value you get with these kits is just FANTASTIC! Excellent price and customer service, super easy to build packs, only one small socket driver required!
Replacing any faulty cells in the middle of the pack is super easy, maybe the easiest design I have ever seen!! All you need is to locate the faulty series, remove the bus bars connecting to the neighbour series and remove the faulty whole parallel group. Even easier you can just remove few bus bars from one side of the pack and find which cells is killing the group =]
Depending on the orientation that the blocks are locked there's no need to use the zip ties that comes with the kit (stationary batteries definitely won't need it). The downside of locking the blocks in different orientation would be replacing a faulty cell in the middle of the pack (it's not impossible but you're just making your life harder when it could be super easy and simple).
The thick bus bars also increase the structural strength of the pack, it feels really strong and solid! Yes, it can handle enough current for most applications.
*if using recycled 18650 cells, make sure the cell terminals (positive & negative) are smooth and clear enough to offer a good contact between the cells and the spring load inside the block.
Love this little DIY battery kit =]
AWESOME video Micah, I'm sharing this video right now!!
Its BRUNO YEEEEEEEEEEEEEEEEEEAAAAAAAAAAAAAAAAAAAAAAHHHHM SO MUCH POWER.. LOL
papagino007 yeaaahhh so much POWAAAAAAAAAAHHHH... hahahahahaa =]
How would you know if the battery is faulty? or if it a bad connector? Either ways, I am willing to take the risk and build a small pack to try it out myself and see how it holds over time.
Festivejelly never got a cent $$$ to say anything about any product!!! I wish I was getting paid hahaha... if I think something is AWESOME I just like to spread the word and help others out there =]
Ohh yeaahhhh
Sonnet Gomes j
Simple idea... great idea...!!!
Thanks...!!!
I'm going to grab a kit. Cheers from Aotearoa NZ.
This is awesome! Can these be used for LiFePo4 cells? Cuz I think they have a different diameter.. please let me know if there is a way to use this for LiFePo4
great job,keep up the good work
Very cool. One suggestion: the individual bus-bar ties should have a narrow part that melts at high current and acts as a crude fuse in case of a fault.
Interesting product. Thanks.
This is excellent invention. One thing that concerns me a bit that if the spring lose tension over time, the batteries may have intermittent connectivity issues during a jerky ride, but I would still like to try these out and see for myself how it holds up over time.
Has this been time and stress tested?
I like this. I can upgrade my battery pack little by little.
Great idea, cant wait to see just how versatile the 18650 will become. This product will set this battery up to work in so many things. Bye bye AA and AAA batts.
Love the idea. But i have watched some videos where some cells don't connect correctly.. my question i understand the plate is spring loaded - but why have a plate and not a spiral type connector - so if the battery pack moves the spiral will always be in contact with the battery...
Great Video! Do you have a video on building a 48V 20Ah battery. What cells and how many do you recommend? Thank you!
18650 cells are all over the place. Diameters and lengths vary +/- .5mm or more. Is that accounted for?
Add springs on the contacts to ensure perfect conductivity
Hi .Would you made up a battery and ship to New Zealand ? Great vids .Thanks Dave
Mikea Can you please do a video lay out for a 12 volt or 4s , or something close battery @17.5 amps, I would like to build one using the snap on caps, thank you, Tj
What's the maximum discharge current your caps can support? i'm building an electric board and i need 80 amps. is this possible with your caps and nickle stripes?
thanks, yes true with the sparks. i'm wondering, the sellers of battery holders or kits like this - don't write the max discharge current supported. also on vruzend.com i couldn't find those informations.thanks for answering :)
Hi Gary, I thought that info was up on vruzend.com, I think in the FAQ's section? So far they've been tested up to 3.5A each per cell, testing is still on going. They aren't yet a high power solution, better for medium to low power projects. But there's a version 2 coming out, probably later this year, that will support higher currents. For now, these are meant more for ebikes and home energy storage/powerwall types purposes, unless you can fit a large AH pack on your board.
Thanks for the Information. ok cool, i will check the second version for sure. like your videos and stuff you're doing. Thanks it helps a lot.
Hey Job91, so far I have not seen any resistance increase over time.
Terrific product for build your own battery packs. If you are still giving away the "DIY Lithium batteries" book it would help when I purchase a half dozen kits. Also very interested in your BMS video. Been looking for a clean way to service pack that will need a replacement battery.
this is great! when will they be back in stock?
hello tanks for the information.... how many batteries i need for 72v 20ah
Why not make the BMS a no need to solder, plug in and bolt part of this kit? AND make it easy to FIND and replace bad batteries....
The way you find faulty batteries is with a multimeter for 5gbp and you use a soldering iron for 15gbp to connect the bms because everyone fucking hates those green terminals that cost a lot to implement, take up a lot of space, are unreliable and so on. Don't do electronics without at least a soldering station! Mine cost 15 with shipping and works with 5+ years zero maintenance and I'm an electronics tinkering eng student.
You just made my day. I was overwhelmed by the prospect of soldering a pack together, but this works so perfectly. Thank you
Also it's awesome that you can change an individual cell that goes bad later down the road. This is a great invention
this would be cool wonder if they are gonna make them for the 26650?
Hi Mikeh (spelling?), it would be cool to make these in a round form factor. Designed in such a way that they connect off set in a zigzag pattern, it would make it easier to build non square packs.
Also, please add global shipping for these, or at least shipping to Australia. Thanks!
dear, I have a question, I have a Scooter with 36v with 3 12V batteries, which model 18650 should I use 10 batteries of 2000ma or 2500ma or 3500ma? thank you and congratulations on the channel is very good.
From Brazil
I am loving this! A couple of questions, if I may:
1. Is the space between the cells a purposeful feature (for air cooling, for instance) or just a by-product of the necessities deriving from the design of the caps?
2. Have you guys also taken into consideration the (much more space-efficient) hexagonal arrangement?
Can't wait to see the BMS part - I'm a newbie and can't tell yet how one could manage the individual loading of so many cells...
Oh, and also: subscribed! :)
1. Both, basically
2. Yes, but it's not currently on the design board. Perhaps in the future, but we've got some other cool features we're working on right now.
Can you make a video on how to assemble a 100ah 12v? There’s a huge market for that in the travel van / rv market, thanks!
I have an Ancheer ebike. The battery is inside a metallic tube that people often mistake for a water bottle. Would something like this work for my setup? I'd need to stack the batteries on top of each other, not make a brick.
Amazing kit
I want to build these for a 36V Golf Cart Battery and it appears I probably need at least 4 of these in parallel. I will probably start with one and get it running. Can the BMS that VRUZEND has handle 10s 10 P and do you have a video to put these in parallel so it make better sense to me. I would think going parallel I would attach each pos to pos and esch neg to neg to each other from each battery as well as then each battery would go to one single point to both the load and the charging post. I would also get a smart charger that could recognize the battery voltage, max recharge and series and parallel set up. Any help would be great and if you have a video that would be good too. I just got the book and I am reading it but I am very visual so the video was perfect.
This holders will get lose in time with vibration.
Also, need to test the current limit of the phisical contact, and the heat generated from high load.
I would use the method only for a stable not movable battery packs, but not for ebike or any e vehicle use
Love these vids so much info
I like your honesty
This a great product and I can see how it can make assembly much easier. There are so many ways to fix the vibration issues mentioned. I would add lock washers to each connection with a nut. You cant stop stupid people from making stupid mistakes, so that's no excuse for thinking these parts are dangerous. Adults are responsible for themselves.
Great intro and review, by one of the developers, no less! :-) Who else would know more about how this thing works? Thank you.
How much is it for this full kit including the batteries. I just subscribed and really want to do a nice simple portable solar set up to go on road trips.
Good idea - can't help but feel the cells themselves could be better designed for this sort of application, but of course they were never designed for mass grouping I don't think. However, there are variations on the 18650 (button or flat top) and I sense the possibility of an EV variant where they are designed better for large batch use. COOLING is the next thing - how about some slim copper ribbon (like a tube but flattened somewhat) and end fittings and junction pieces, so cooling can be taken care of? That would be an important serious next-level step? For allowing mass cooling by threading such hollow-ribbon copper a cooling system could be implemented?
The first video of yours that I saw (DIY E-Bike battery build) was great! I paused this one @3:09 to start purchasing My "Bat Legos"! I have so many uses for these! Very excited! Will "Sub" of course!
I'm curious about the spring contracts. Under what acceleration does the battery disconnect?
How is it you are not getting shocked when touching all the exposed terminals? This is new to me. Also, shouldn’t there be fuses in here somewhere, like between the cells?
Shocks are supplied by alternating current (AC). Batteries are direct current (DC). You will start to cook yourself at very high voltages DC, but you won't shock yourself. Because you have thick calloused skin acting as a high ohm resistor, you won't actually cook yourself unless you wet your fingers and hold tight at both opposing terminals. You probably need around 90 volts minimum to start risking danger to yourself. I think this is a 36 volt pack without rewatching the video.
Battery packs aren't usually fused internally, but you could do so to prevent a critical meltdown from damaged cell sets causing uneven and high discharge currents within the pack.
Great idea. If the battery is expandable could it be used in a larger scale for solar power?
Absolutely
is there something similar open source for 3d printing?
Brilliant ,, saves time and a lot of welding or soldering fantastic,, do you ship to the U.K. Please cheers Shane
For how much can you build a 24 v 12 Ah battery for an e-bike with this system ?
