I’ve followed and have used all versions. While the earliest versions had limitations, they still serve my needs. V1 24v packs have been powering yard lights and charged by solar panel since the became available. The newest version seems the result of brilliant young engineers committed to DIY builders. Evaluating, improving, and listening to customers. While the competition claims they are superior is more sales blather than fact. The exciting possibilities of morphing into user repairable and buildable packs is forward thinking. No, I don’t hard a financial interest in Vruzend. I do have more than half a decade of emails and PMs from two of the most reliable and honest young dreamers I’ve met. I’d be proud to call both a son or at least a valued friend. BTW have had Sunnko, Kweld, and JP welders too.
As always, another nice demonstration. Thanks, Micah. This is excellent example, when you have used batteries and some of them fail, then you can replace only those affected, not tearing apart the whole pack. Exactly what I need.
From some of the videos I’ve watched, they say that all used batteries should be replaced regardless when any battery is replaced because you can’t guarantee that they are equal in all regards. To be fair, I don’t know anything about battery packs and this may or may not be solid advice so take with a pinch of salt.
@@BadPractices i had a thought. Bcuz we replace just one or two cells, means those new cycles are out of sync with other older ones that have more cycles, therefore more difficulty of balancing between them.
I used this kit to put together a 14.4V, 10.2 Ah battery pack for portable ham radio operations. First time out the radio was used at 50-75 Watts output for right at 5 hours, and still had plenty of battery power in reserve. Outstanding kit!
This is my fourth kit (v2 and v2.1). For sure buy 2.1. Life will be a bit easier. Also, there is a reason he is wearing gloves. That well made plastic can be a pain, especially if you don't follow instructions (video) and need a do-over! :) I highly recommend this kit for those that do not want to spot weld. It truly is like lego pieces! Life is good!
Can't wait to use these for future projects! I built a 14s 7p with 2.0 kit. I loved the design but it needed a lot of time to get all the caps fully on. It is great to see that you are invested in your product because the 2.1 seems so far way better. Also nice job giving a good tutorial. I see potential for the whole diy community.
the Vruzend company is a fraud they will steal your money and never send you your product. I purchased 6 kits from them on 11/28/2022 and they never sent me my kits. I have contacted them everyday for three weeks and they will not respond. stay away from this comp[any they are scammers.
Thank you very much sir. We are a startup doing convertion for old vintage bikes and cars. We thank you for guiding us with your very valuable information. A true mission to save the environment and MOTHER EARTH.
Looks easy putting it together. I would hate taking it apart to fish for bad, unbalanced cells. PVC pipe with threaded end caps are still my choice for cheap , tough, cell holders. 1” thin wall pipe for 26650 cells…3/4” schedule 40 for 18650 cells. Tight fit but not too tight , and cells can be extracted after removing one end cap and extracting with telescopic magnet for individual charge/ balancing in single or dual digital display chargers.Cell to cell direct series connection, no soldering, no welding, no itty bitty nuts and bolts to tighten. Hillbilly ingenuity does it again.. does fer me!
I am late to this party but at age 69 and with COVID-19 still on the growth cycle I am glad to still be in this world. I have been searching for a battery packaging system for 12.6 (3 cell lithium ion) and 16.8 packs (4 cell lithium ion) for a portable power pack so I can change out 1 battery without having to resolder everything. I use plugs on all connections. I am NOT running a DC motor. This also gives my customers the selection for Lithium LiFe04 batteries if they want them. J The ability to replace one cell WITHOUT HAVE TO solder to each battery end verses just bolting them in place is BOTH simplicity, genius and the sign of a very experienced and knowledgeable maker. In the old days government called it Research & Development. The reality is Retry and Do it again till you get it right is what this experienced is absolutely perfect for my design. Hope bus bars for 26650 LiFe04 2600mah 55A Vascell arrays are on your future product design list too. In FlorDAH we have been know to be without AC power for extended times due to Andrew, Charley, Matthew, Irma and now Sally with more to come every year. Beats running noisy ass generators running for hours. I also hope this write up confirms I can suck up real good to both customers and winning a book. This maker actually got his first patent 4,104,695 back in 1978. Most likely before have of your viewers were even conceived. Harry Regician. Regeration is my game plan.
i can make any coinfiguration battery pack 12.6v 16.8v 25.2 v and on with sal short bits of neg and pos wire salvaged from cable cut and stripped a few rolls of mini sellotape and few rolls of black tape some 4mm connenecter and 4mm terminals with 5.5mmx1. 5mm connecter to charge
Here is the Man whom should i have to follow....to learn how to play with li-ion battery 18650. thank you very much for your simple explanation of how to work with 18650.
I have been looking or researching this type of building lithium battery without welding for my ebike, escooter, golf push carts. Thank you for inventing this gadget.
@@ebubekirelladin7471 Yes. If you don't, one of the battery will cause the others to no longer charge or doesn't conduct at all. Example: One is at 3.9v and the other is at 4.2 (full charge). The 3.9 will no longer charge. Or, one of the battery isn't properly attached and makes it 1 voltage less, ruining the Series connectors.
Just finished assembly of a 4s7p battery with LG MJ1 cells and the V2.1 kit. Everything is working great NOW. The reason it did not work at first was totally my fault. Even though I had watched this video and your video from a couple of years ago cautioning us to follow the recommended assembly method; I decided to take a short cut. What a mistake! I have three suggestions for anyone considering making an 18650 battery. First. you won't go wrong with the Vruzend V2.1 kit, Second, if you are an older guy, like I am and don't quite have the hand strength that you had a few years ago, use a ratchet clamp (I used it on individual cells even.) And last, please, please pay careful attention to the orientation of the caps before you put them on, as Micah says use a system!
YOU DID IT!!!!!! Ive been wanting to buy theses but was worried about the rattling while riding a custom ebike your the best awesome job keep up the good work
Hi Micah, last year I got your DYI Lithium Batteries to build a spare battery for my Ebike. I'm glad I waited till the V2.1 kit came out. I am excited to start building this and also a battery system for my Ham Radio set up. Nice work. Joe KG7DTF
@@lordnox69 unfortunately I have not done anything in that regard. My level of lethargy and procrastination are preposterous. I built a small 24v pack with parts of the kit and tested out the motor + controller + throttle setup and everything works well. I've built have a wooden chassis, wheels and a rod I wanna use for the rear axle. All I need to do is build the front wheel steering/controls and bring all the parts together. Alas procrastination will not let me be great. Oh, I also need a BMS or balance charging system. What are you up to?
@@lordnox69 unfortunately I have not done anything in that regard. My level of lethargy and procrastination are preposterous. I built a small 24v pack and tested out the motor + controller + throttle setup and everything works well. I also have a wooden chassis, wheels a I keep blaming
Wow I'm so glad I found this - great product. My friend built some batteries with a spot welder and had lots of trouble - I thought no way can I build a battery - until I randomly found Vruzend on an e-bike forum. Thanks for making such a handy product - can't wait to give it a try!
I'm disassembling my battery pack as I write this. Many of the plastic caps are not only cracked but have fallen apart. Micah had a great idea and it seemed like the way to go, but no cigar for effort. I gotta say I will continue to follow him for his great e-bike related reviews and keeping me up to date on the latest technology. But as far as these caps go, use your money to invest in a spot welder. It'll save you lots of time in the future, not to mention your e-bike power loss at the most inconvenient time.
Great product. Just built my first 36V battery following your excellent video instruction and it works fine. I will be building more soon. Question: can you do a short video on how to detect and replace a bad cell, if necessary? Thanks again!
Wow! This is the second battery building video of yours that I have watched; fantastic! I just bought my LectricXP ebike as my first electric bike, and I was wondering what it's battery is all about. Now, I have a pretty good idea. I guess when it comes to repowering it, I will have someone like you do it. This video shows why the battery builders are worth their money! Thanks again
Getting started on the prep work I need to build my first battery build. I have two projects in mind for this build, 12 volt battery and a 36 volt battery.
Cool, this is just what I'm going to need to build my hotrod powerchair. Needs to be 24V high amps and large capacity/Ah rating, prolly 100Ah battery pack. Thanks for sharing.
I love people in 2020! I'm using this to build an FPV drone that runs on 4g satellites with my 17.5Ah battery giving me continuous 11V power (for about 3-4 hours of flight time)
Very nice kit, has some advantages over welding like: Can easily remove a bad cell; no welding needed and all that goes with it all; you can make an ever expanding battery or several large batteries as you get materials.
I've just started watching these battery build videos, how great! I think I'll be ready to build my own battery soon with one of these kits, thanks for all the info!
Good to see the new addition of the barrel bolts. I had a catastrophic failure with the 2.0 kit when the pack seperated slightly after using on and EBike for 60 miles or so. Was using zip ties to compress a 10s3p pack. Looking at this new mechanism, I would be happy to recommend again.
The new kit looks great, it a nice improvement over the previous one. I’ve been tempted to try and build my own battery for a while now but after looking into the price of new quality cells and other materials to build a battery it’s hard to see where the major savings will come from building your own. I’ve heard of people harvesting battery’s from used devices to make their own, is this something you would recommend or have tried yourself? If so I know used laptop batteries seem to be a good cheap option but are there any other batteries you would recommend as a good cheap source? Looking forward to following your future releases.
This is awesome. I am new to building and I was a little intimidated about spot welding. I building my first Ebike and this will make the battery part a little easier to do.
Thanks bud, really well done and informative piece. The sound , the lighting, the editing, your physicality and balance of instruction with the learning experience (or fun) are excellent. Outstanding. A person with vision problems would be able to follow on and build these batteries. I'm so glad the ebike community is rich in diversity and talent. And "stuff" worth listening to.
@Joshua Owen Just head to the Vruzend website and add to cart all the items he uses. I did that just now and came up with a total of $54.95 without any battery cells. With 30x 18659 cells to fill every connector supplied in the kit, it will be an extra $149.85 for the most expensive pair listed. This can make you any number of combinations and will be the total cost of $204.80 (excluding shipping and I didn't add the kapton tape or nut driver) If you only want a 12V battery as a reserve pack for say camping lights, you could use some of the version 2.1 connectors in a 4s4p configuration. The cost if you ONLY wanted the exact cells for that kit would be: 16x 18650 cells, the v2.1 30 cell mounting kit, 4s BMS, heat-shrink, a black and red 14AWG wire for $134.87. This would be a 14.4v 14000mAH pack (14AH). However, if you had your own cells from recycled laptop batteries then you wouldn't need to buy the new 18650 cells and could get away with the $54.95 price for the assembly kit pieces. Just make sure the cells are all good first.
First off - excellent product and idea! Secondly, as someone who makes a lot of batteries but still not enough to justify much machinery or manufacturing space - it would be nice if you could supply each part of the kit separately on vruzend or provide price breaks at quantities.
Oh yeah,, I'm sold now, I like this set up better, more redundancy to insure the batteries make contact, I'm going to purchase a small kit first (to learn) Then order the kit for my powerwall (6kw) bank
Why is this question not answered? All this battery stuff is great but everyone seems to assume that we all have EE degrees...how about a video that explains how to decide about amps and volts for any application...why one way is better or worse than another....especially concerning powerwalls hooked to grid-tied systems.....BASICS.....TEACHING!
I have this and am generally pleased with it but I have comments and suggestion. I didnt receive anywhere near the right number of "barrel bolts and plates. Also when pushing the caps over the cells it's a tight fit on most cells which is good, but it ends up compressing the air inside and like a spring, they tend to pop out a bit. I put the entire pack between 2 2x4s and gently squeezed them all on in a vise being careful not to over tighten. But if there were tiny holes in the caps they would allow the air to escape making assembly and disassembly easier.
Love your videos! I do paragliding but I am planning to get into electric paramotoring do you have any details on the paramotor battery that you mentioned on your videos? Thanks.
My brain just exploded. ELECTRIC PARAMOTOR!!!!!!! such an amazing progression. Glad to read this comment and discover people who are pushing this field of e-flight
It looks very appealing...BUT, anyone who is practical will not use this in a million years. This thing needs serious engineering before it becomes viable
I bought these and had them for a while just used the kit to build a 24v 7s I believe it was 49 cells in total was super easy ..now I’m planning on buying more
So much information. I can see these kits lowering the prices of the OEM batteries. It is just over $1100 CAD for a 48v 14ah replacement pack for my Surface604 Shred eBike after taxes and shipping etc... get taken into account. The list price on the website is $799 for the pack which on it's own is more than enough for the components and workmanship that goes into making one. The lithium battery scene for OEM packs is criminal for the amount of money that they charge a 9 cell Milwaukee extra large battery costs an insane $279 before taxes. $18 for the cells and maybe around a very generous $50 for the brain box BMS and such and that's when you aren't buying in bulk. I'm So glad that someone came up with a kit like the Vruzend. I found out that it existed during my research on designing one myself. If only had had been faster off the mark. Anyway I'm about to shave off $600 to $800 off that $1100+ price tag and build my bike a 48v 20ah pack. Save tons and get more chooch for you're chotch.
User friendly. I doubt the shortage depends on the nicd or you rather suggest lithium ion. OEM batteries may have shortages. Which type and which brands of batteries are optimized with the kit?
Hi, this is the 2nd video that I watch on your series. The 1st video was on "How do you know if a battery is good quality?". I find both of these video very informative and useful. This is a website that I can learn from. Thank you. Wilfred from Singapore.
Your video was excellent. I will probably be getting your book. Even the product you were advertising looks pretty cool. The only problem is the kits are so expensive that for the cost of 2 kits you can buy a spot welder.
Where weight is a big issue, I wouldn't use the Vruzend kit because it does add weight to the project. Therefor the solar car and the paramotor are not very likely to use Vruzend. Vruzend also adds size to the battery. In super large batteries I would think of fusing the single cells (like Tesla does) or fusing the parallel connections. The BMS only protects the serial groups (and only to a certain extend). Instead of the parallel bars you could use little glass fuses of 2A or 3A. You can easily solder those on, also when using the Vruzend kit. Those glass fuses only cost a few bucks per 100 and are most probably even cheaper than the parallel bars.
Thanks for continuing to write and develop these concepts. While I understand your emphasis is bikes, I'd like to see some perspective on micro cars or neighborhood cars for those of us who are too unsteady for 2 wheels!
I really love with passion, the great work by way of research and openness to deliver your teaching in very simple and easy way that enables everyone to understand. You lay good emphasis on areas of new developments and dangerous ones to extra careful about when venturing into lithium ion battery projects. Mica Toll is a great source of inspiration to many DIY enthusiasts like me. More Grease and more grace to you Sir!😄👍
Hi Micah. I have the kit and the physical assembly is done. Next step is bms, wrapping etc But I do have a question. I notice there’s no cell to cell fuses in your system. Lots of others make copper bus bars with individual fuses between cells. Is there a reason you don’t think cell fuses are needed, even on bigger packs with lots of batteries in parallel?
As a person looking for a battery for a solar powered generator and a ham radio this looks like it would be a great idea for that. What is your thought(s) on that?
I really don't know why it took so long for someone to design these for project use, nice job. I was considering building a motorcycle starting battery and car battery out of 18650 cells.
A very useful how to video building battery packs, it is not an intuitive process until you see how it is done to build correctly and not create dangerous shorts with li-Ion batteries

Thanks bud, really well done and informative piece. The sound , the lighting, the editing, your physicality and balance of instruction with the learning experience (or fun) are excellent. Outstanding. A person with vision problems would be able to follow on and build these batteries. I'm so glad the ebike community is rich in diversity and talent. And "stuff" worth listening to.
I am curious what the "average" total cost would be for the entire battery build from this video including all parts?
@Joshua Owen Just head to the Vruzend website and add to cart all the items he uses.
I did that just now and came up with a total of $54.95 without any battery cells.
With 30x 18659 cells to fill every connector supplied in the kit, it will be an extra $149.85 for the most expensive pair listed. This can make you any number of combinations and will be the total cost of $204.80 (excluding shipping and I didn't add the kapton tape or nut driver)
If you only want a 12V battery as a reserve pack for say camping lights, you could use some of the version 2.1 connectors in a 4s4p configuration. The cost if you ONLY wanted the exact cells for that kit would be: 16x 18650 cells, the v2.1 30 cell mounting kit, 4s BMS, heat-shrink, a black and red 14AWG wire for $134.87. This would be a 14.4v 14000mAH pack (14AH).
However, if you had your own cells from recycled laptop batteries then you wouldn't need to buy the new 18650 cells and could get away with the $54.95 price for the assembly kit pieces. Just make sure the cells are all good first.
I'm super happy to find this set up. I've ordered a set to build a battery system for my solar panels.
When it comes time to rebuild my battery from my ebike I will be using this! Thanks.
I have this kit, and it is a dream to work with. I definitely suggest it. :)
great help sir here from manila
Too damn broke to buy the kit
First off - excellent product and idea! Secondly, as someone who makes a lot of batteries but still not enough to justify much machinery or manufacturing space - it would be nice if you could supply each part of the kit separately on vruzend or provide price breaks at quantities.
Oh yeah,, I'm sold now, I like this set up better, more redundancy to insure the batteries make contact, I'm going to purchase a small kit first (to learn)
Then order the kit for my powerwall (6kw) bank
I have no idea of how to build a good and safe battery, but, now I want to build one for my camper. This looks like a pretty simple project.
Great video. I am going to build a 36v 20ah battery for my e bike using one of these kits.
This is a great site for getting all the information on how to make your own battery pack for an E-Bike
Does your book cover home "Power Wall" Build information? Great video!!
Why is this question not answered? All this battery stuff is great but everyone seems to assume that we all have EE degrees...how about a video that explains how to decide about amps and volts for any application...why one way is better or worse than another....especially concerning powerwalls hooked to grid-tied systems.....BASICS.....TEACHING!
Solutions are rare on RUclips thank you no waste of time just perfect information thank you again
Hey another diy battery channel to add to my collection. New here but love your stuff
I have this and am generally pleased with it but I have comments and suggestion. I didnt receive anywhere near the right number of "barrel bolts and plates. Also when pushing the caps over the cells it's a tight fit on most cells which is good, but it ends up compressing the air inside and like a spring, they tend to pop out a bit. I put the entire pack between 2 2x4s and gently squeezed them all on in a vise being careful not to over tighten. But if there were tiny holes in the caps they would allow the air to escape making assembly and disassembly easier.
Nice one
Please show us 72v 40ah or 42ah or 45ah battery building with this kit
That's gonna be huge! Be very very careful, you're going to have a lot of power to short
14S20P battery at 9:33 , so 58v range
The simple ideas always work the best. This product is not only simple but very effective. I will use this product very soon.
Love your videos! I do paragliding but I am planning to get into electric paramotoring do you have any details on the paramotor battery that you mentioned on your videos?
Thanks.
My brain just exploded. ELECTRIC PARAMOTOR!!!!!!! such an amazing progression. Glad to read this comment and discover people who are pushing this field of e-flight
Have two Prophete e-bikes both with bad batteries. This is just the ticket to help repair them. Great video, easy to follow, thanks!
It looks very appealing...BUT, anyone who is practical will not use this in a million years. This thing needs serious engineering before it becomes viable
I bought these and had them for a while just used the kit to build a 24v 7s I believe it was 49 cells in total was super easy ..now I’m planning on buying more
He almost had me talked into buying this until he said "This is where you have to add your nuts" Nope I'm out of here!!
err well you have to fasten them together somehow
because with welding.....there is another way. Read title
So much information. I can see these kits lowering the prices of the OEM batteries. It is just over $1100 CAD for a 48v 14ah replacement pack for my Surface604 Shred eBike after taxes and shipping etc... get taken into account. The list price on the website is $799 for the pack which on it's own is more than enough for the components and workmanship that goes into making one. The lithium battery scene for OEM packs is criminal for the amount of money that they charge a 9 cell Milwaukee extra large battery costs an insane $279 before taxes. $18 for the cells and maybe around a very generous $50 for the brain box BMS and such and that's when you aren't buying in bulk. I'm So glad that someone came up with a kit like the Vruzend. I found out that it existed during my research on designing one myself. If only had had been faster off the mark. Anyway I'm about to shave off $600 to $800 off that $1100+ price tag and build my bike a 48v 20ah pack. Save tons and get more chooch for you're chotch.
Best build 18650 battery pack ever seen. Thanks
This seems like a nice improvement. I have a V1 system, but for any future builds this is certainly the way to go!
Very nice improvements. Glad to see that progress hasn't been stifled.
Looks like a great update to an already cool product.
User friendly. I doubt the shortage depends on the nicd or you rather suggest lithium ion. OEM batteries may have shortages. Which type and which brands of batteries are optimized with the kit?
when one cell goes bad, you can disassemble the pack and easily change bad cell, that's a big positive 👍
Great explanation on the battery build, can't wait to build a battery.
Hi, this is the 2nd video that I watch on your series. The 1st video was on "How do you know if a battery is good quality?". I find both of these video very informative and useful. This is a website that I can learn from. Thank you. Wilfred from Singapore.
Awesome video. This kit looks alot more sturdy than the older ones.
Your video was excellent. I will probably be getting your book. Even the product you were advertising looks pretty cool. The only problem is the kits are so expensive that for the cost of 2 kits you can buy a spot welder.
A very nice improvement over the previous version
Here is Brazil, congratulations for your quality.
Excellent tutorial. I'm a newbie watching your videos and I am please with the ease and simplicity of how to build these batteries. Good Job!
Well sandwich plates do work, but you guys recognized a problem with v1.5 and you improved it. Way to go!
Where weight is a big issue, I wouldn't use the Vruzend kit because it does add weight to the project.
Therefor the solar car and the paramotor are not very likely to use Vruzend. Vruzend also adds size to the battery.
In super large batteries I would think of fusing the single cells (like Tesla does) or fusing the parallel connections.
The BMS only protects the serial groups (and only to a certain extend). Instead of the parallel bars you could use little glass fuses of 2A or 3A. You can easily solder those on, also when using the Vruzend kit. Those glass fuses only cost a few bucks per 100 and are most probably even cheaper than the parallel bars.
Will you have kits available for 26650 size cells? That would be sweet for lifepo4 cells
Can’t stop watching these videos. Keep up the great work good sir.
Thanks for continuing to write and develop these concepts. While I understand your emphasis is bikes, I'd like to see some perspective on micro cars or neighborhood cars for those of us who are too unsteady for 2 wheels!
I really love with passion, the great work by way of research and openness to deliver your teaching in very simple and easy way that enables everyone to understand. You lay good emphasis on areas of new developments and dangerous ones to extra careful about when venturing into lithium ion battery projects. Mica Toll is a great source of inspiration to many DIY enthusiasts like me. More Grease and more grace to you Sir!😄👍
Just bought the 2.1 kit and BMS going to be doing a Amateur radio Battery build for my Vietnam era Back Pack radio.jim
Hi Micah. I have the kit and the physical assembly is done. Next step is bms, wrapping etc
But I do have a question. I notice there’s no cell to cell fuses in your system. Lots of others make copper bus bars with individual fuses between cells.
Is there a reason you don’t think cell fuses are needed, even on bigger packs with lots of batteries in parallel?
Cool, lesser solder Smoke and eliminating the necessity of Nickel Terminal welding, nice, safe Packing all the cells together.
I built my daughter a tiny house and now I need to build a battery pack to power it up. I will check you guys out further. Thanks!
I'm just getting into building my own e bike and this new Vruzend V2.1 looks like a winner . thanks for the info
Like the new system wth the nuts and bolts ,thank you, looking forward to other battery projects
Would be nice if you sold complete kit where I choose which battery and the desired V/AH and you provide all the necessary items!
I like battery building. I’m a novice to e bikes and as I learn I am branching out in different directions.
do you need to measure all of them one by one
quick question..what if i wanted 72v/60ah 5kwh? how much battery do i need and on what order? 10x6?
As a person looking for a battery for a solar powered generator and a ham radio this looks like it would be a great idea for that. What is your thought(s) on that?
The kit is nice,easy and safe too for beginners 👍
I want to make a backup battery kit for my power mobility scooter and this looks like the best way for me.
So what's better, building your own battery pack or buying a lead acid battery? In terms of price to performance ratio
Glad I found this D.I.Y battery video,I will use this new kit version for a motorcycle battery build.
I really don't know why it took so long for someone to design these for project use, nice job. I was considering building a motorcycle starting battery and car battery out of 18650 cells.
I'm looking at doing that too! Got any insight you only need 9ah from what I know to crank. I got a little 250 that I want to build one of these for
A very useful how to video building battery packs, it is not an intuitive process until you see how it is done to build correctly and not create dangerous shorts with li-Ion batteries
My battery issues will be solved by v2.1 for my robotic projects. Thank you for video
