New & improved Vruzend V2.1 no-weld 18650 kit

[@moonwalker573]

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.

[@BadPractices]

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.

[@luqmanhakimnoorhisham5402]

@@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.

[@thomasjaszewski64]

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.

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!

[@glock35ipsc]

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!

[@Soren.iz.snoren]

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.

[@morrisdonald]

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.

I like this connection system, although I'd recommend using blue locktite on the barrel bolts if they are used in a high vibration environment.

[@allthehobbiesbrady]

I really like this. Make me feel a lot more comfortable building my own battery. Thanks

[@ebubekirelladin7471]

do you need to measure all of them one by one

[@LeonCamero]

@@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.

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!

[@ginnynewman317]

I love to build ebikes, but for some reason I'm afraid to build a battery. Will take the plunge someday! These look like a great way to ease into it!

[@keithballard4621]

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!

[@lonnielister]

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!

[@josephrobertson5555]

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

[@jaysway007]

I am curious what the "average" total cost would be for the entire battery build from this video including all parts?

[@KegRaider]

@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.

[@Lee-007xxx]

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.

[@edwinkania5286]

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.

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!

[@davederryberry7474]

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.

[@catalinchereches3058]

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

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.

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.

[@pleasecho2]

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.

Hi, Mike, I like this system to build a battery pack, a really good idea, But the best I noticed and you did not mention is the cooling effect that this pack can have. Before sealing all the battery wouldn't it be a better idea to make one sleeve with a cooling fan on the front, blowing the cool air through the tunnel of batteries? Really just an idea as I have been reading that electric car batteries have liquid cooling but I know the loads are much higher than a bicycle. Thank you love your work.
