I can confirm.... I had one of those older color coded kits and they all split open. I mailed and got a brand new kind in 4 days !! Really great service guys.
I bought part of a pack from someone who over ordered. I`ve put together a top tube pannier with 40 cells.I have zero experience. Lot`s of instructions and tips on youtube. It`s very adaptable even when you can`t fit the cells in a single block. I paralleled them to my original pack and doubled the range. Worked first time.
Can't wait to build my ebike for the 4 mile morning commute! Love that there is a community and demand for this product - Gives you hope for the future :)
I built a starter battery for my lawn mower with the original version. Stacking 3 bus bars was quite difficult for me, so I'm particularly glad to see that this has been addressed. The battery is still working perfectly after a season of mowing. :)
Thank u! I haven’t built a battery yet. But one definite advantage is that u can reuse or reconfigure. With spot welding, it would b hard to take it apart.
Thanks for the update. Sounds to me like you have made huge progress coming down the learning curve on this very innovative approach to assembling 18650 packs. I will be ordering a V2 kit just as soon as they are available on your VruzendUSA site. Very exciting advances in your initial offering and very quickly developed and tested. Thanks for all the hard work !
Love your demeanor and style of presentation! As a beginner, it is nice to see someone who is Interested in helping people. I could see these kits becoming a go to for college and high school instructors! Collecting batteries now...
Great update; I'm really happy to hear about the progress of the v2 caps. The limitations on current with the v1 caps was a deal breaker for me, but now a modular DIY kit seems viable for my ebike projects. I'm also very impressed by you production timeline and how quickly you're able to iterate on your design and implement improvements. Kudos!!
I just want to say that your videos are so empowering! (no pun intended) I feel like I can do anything with this knowledge! Now I know how to build a battery I can use to store solar power for my home! And customize and upgrade my low powered E-bike. So thank you for this incredible information. :)
Yessss the high power VRUZEND is coming ohhh yeaahhh exciting times ahead haha... love the copper connections and all the plastic improvements. All these details make a lot of difference. VRUZEND POWEEEEEERRR
Awesome guys! Now we are talking! Version 1.5 is very nice upgrade and Version 2 with 12A+ will be game changer for people with high current cells. Good luck you guys I wish you best luck with testing and production! Gratings from Sweden! :)
Loving your DIY lithium ion book...working through it with my son and planning an electric gokart to polish our mechanical skills too!! Keep it up your writing is really accessible!
Thanks for sharing the extra stuff at end of vid, i just ordered my 1.5 kit, and i received your battery book yesterday, im a first time ebike and battery builder that appreciates all the knowledge you share.
Glad to see you take feedback from your customers and work to make an already good product better. I always wondered why you chose red and blue for the caps instead of red and black :) Wishing you success in all your endeavors.
Thanks! Mostly so it just stands out a bit more and doesn't look like some other options out there. We figure with red and blue, its still pretty obvious which one is which.
Wow Gonna have to get me some of these things. So far, I have been trying to join the cells together using soldering. Failed miserably, solder really does not like to take to 18650s. Resorted to buying hordes of cheap 'DIY power bank' kits from China, sawing off the electronics, and just using them for the spring loaded 18650 carriages, and soldering *them* together.
To me, that's the only way to do business. Especially when you're competing with cheap stuff from sweat shops in third world countries, you have to not only have a better product, but better service too. I don't want to deal with a company that doesn't stand behind what they sell, so I always make sure my own products and businesses are held to the same standard.
Hey Mika, Can you follow through on your battery and show a video of the connections, charger and the battery actually working on a bike, ride-on golf cart, mobility bike - anything
Thanks for the reply on % of an 18650. Next question: I bought 200 harvested lg 2200mah that were advertised as lgds but received a mix of lgds, lgdas, lgcas. What kind of battery am I looking for in my ebike. I've started to look at data sheets but don't yet understand. If this was explained in your battery pack build guide, sorry, but I haven't won a book yet! When I get steady work I'll buy one. My next book by Micah Toll: Batteries: Different types and how to use them. You can use this title for your next book and all it'll cost you is yourDIY
Great improvements to v1.5...definitely needed. However, none of those improvements address the single biggest issue with v1: the size of the opening is too small. I'd say every fifth battery of mine had the shrink wrap split open because it took so much effort to jam the cap on due to the extremely tight fit. Increasing the patency would allow easier assembly of packs. You said it yourself: the actual diameter of different brands of batteries varies. The solution isn't to add a thicker wall; it's to widen the opening.
Good point. I didn't explicitly mention it, but part of the reason of switching polymers was to address this. It wasn't that the hole was too small, it was that the polymer was too rigid. This new polymer has a bit more stretch to it so now the cells slide in much easier as the plastic is smoother and stretchier. That means that the cells are held better and don't need to be forced in as hard.
DIY solar power? Didn't realize you had that available. Congrats! Hopefully your new Vruzend 2.0 can handle 20amps sustained so it can handle 1500watts peak motors.
Hey Micah. Thanks for the great videos! When ordering the Vruzend V1.5 kit, does that come with the nut driver or should that be ordered separately? Cheers.
Sweet! I haven't gotten around to ordering my kit yet, and now it just got better. So, do I wait for the V2 to show up. Hmmmmmmm Decisions, decisions, decisions. It will probably be August or September before I order. Might just get the high power.
It's awesome that you are putting out so much good information and continuously improving your product. Have you used temperature sensors on any of your battery packs? Given the new caps will carry more current and one of your recent videos about battery temperature, I'm wondering what you recommend for monitoring battery temps. I built a battery for my trolling motor, I used Samsung INR18650-15L which are rated for 18A (at 25℃). I'm sure temperature shouldn't be an issue, but wondering about options.
Looking more attractive with the copper, your getting more of my attention . In the future do you have any plans for a kit that we could use on larger batteries such as the 20700 Or is there a logical reason besides bigger battery that I haven't seen any battery packs with larger batteries Love your diy battery book looking forward to building a battery
Nice video bud hope the new vruzen are better than the old ones. I have ordered althow i havent resived them yeat so i really need a video for a 60v+ or 72v triangle battery.
How long do you think we will have to wait for 20700 or 21700 batteries to become the norm for ebikes. I will be building my own battery but preferably with larger capacity cells A few years ago I built my first ebikes 6months later a better more stable motor was released of course I had to upgrade Now my gut tells me 18650 cells will be a thing of the past soon I don't want a repeat my motor dilemma Looking forward to building my custom battery
We had a good effort by the students, and are working toward next year's continuation of the project! We did end up with splits in most of the caps from our sets, so I'm glad to see in the next generation they are both more robust plastic caps and spring terminals are capable of carrying more current too.
Fantastic updates, I am looking forward to making a large order in coming weeks. What is the exact diameter (width) of the version 1.5 caps when they are connected? Let's say two connected?
Like some of the other Ytubers on here when building a battery using 18650s they talk about fusing the cells, how do you/would you go about that in using this kit? Im also looking more towards power wall cells instead of powering transport. I like this idea because of my lack of soldering skills.
Thanks for the info bud! I just got an original Phat Scooter(sport model) 1200 watt with a 72V 20ah battery. I do deliveries around the University of Arizona with it. I'm looking for a way to add a second battery to double my range and possibly hack the motor to get more speed. What are my options. Is it possible to build a battery and have it be portable so that I can easily unplug it and take it with me when not in use? Cheers!
I can confirm.... I had one of those older color coded kits and they all split open. I mailed and got a brand new kind in 4 days !! Really great service guys.

Love your content. I'm working on upgrading my Emmo Knight from lead acid to lithium. Your videos are a huge help!
Awesome guys! Now we are talking! Version 1.5 is very nice upgrade and Version 2 with 12A+ will be game changer for people with high current cells. Good luck you guys I wish you best luck with testing and production! Gratings from Sweden! :)
Loving your DIY lithium ion book...working through it with my son and planning an electric gokart to polish our mechanical skills too!! Keep it up your writing is really accessible!
New to the ebike craze. Learning a lot here.
I’ve been watching your videos and I am impressed with your product innovation. Even I can understand how to put them together.
Thanks for sharing the extra stuff at end of vid, i just ordered my 1.5 kit, and i received your battery book yesterday, im a first time ebike and battery builder that appreciates all the knowledge you share.
Thanks for your support, Andrew!

Hoping version 2 out soon. Can't wait to get started!
thank you for improving your product and keeping your product and company integrity
I just purchased a ebike and want a second battery your kit looks like a winner
Looking forward to vruzend 2.0. Thank you, Micah.
Wow
Gonna have to get me some of these things.

Excellent!! Looking forward to the V2 kit so I can build a pack for my Fat Bike.
the cool thing about the old caps is if you get frustrated, you can brute force the caps and they'll snap together if you can't slide the grooves.
Good to know and see that you stand behind your products and they keep improving.
To me, that's the only way to do business. Especially when you're competing with cheap stuff from sweat shops in third world countries, you have to not only have a better product, but better service too. I don't want to deal with a company that doesn't stand behind what they sell, so I always make sure my own products and businesses are held to the same standard.
very cool hoping you get the v2.1 back in stock soon
With ur smile.. u make a very good presenter👍
Looking forward to the v2 Kits.
Looking forward to version 2.0
Thanks for the update
Still looking forward to V2?
I would very much love a book - either of them :)
Can't wait for the latest and greatest products!
Great product! I am looking forward to building a 52volt 20ah when the 2.0 version arrives!
Nice developement. It will be great for e bike enthusiasts to play with the currents and voltages
Man I love them Legos love to have a set but can't afford them right now but good job man
Awesome, nice update and cant wait for the V2.
Had read your book on batteries. Got good info on the batteries as a newbie. Hoping to learn more.
Can't wait to see the higher rating. Thanks micha
I love your videos and the positive energy you put in the project(s)!
Great stuff - just ordered V1 kit - will be ordering V2!
I also received one of the new blue and red kits and I've had no probs with it. Thanks Micah, look forward to the 2.0's. 🔋🔋🔋⚡️⚡️⚡️⚛⚛⚛
Great progress! Im looking forward to the new ver 2 kits. Itll be a great upgrade for my battery packs. Keep up the hard work!
Hey Mika, Can you follow through on your battery and show a video of the connections, charger and the battery actually working on a bike, ride-on golf cart, mobility bike - anything
Cant wait to get building my battery
I have just started watching and am now a loyal follower. I am looking forward to the next video and future improvements to battery science.

Cool.. Can't wait for V2
Totally gonna get the V2 caps when they're available

I just ordered today - Maybe a discount on the v2 when available. Good video - guess I'll watch every week.
Great! Can’t wait to get mine! Thanks for the wonderful videos

Hey Micah. Thanks for the great videos! When ordering the Vruzend V1.5 kit, does that come with the nut driver or should that be ordered separately? Cheers.
Love the idea of your' products . LOOKING forward to ordering soon !?!?!? 🔋🚲 🍁
Keep up the great work Micah! ill be buying some v2's when they are released
I found you by watching Julian OH9STN youtube channel Great product for Ham Radio thanks
This will be a game changer
V2 is looking good.
Just what I am looking for...going to need to replace my Battery Packs in my Electric Lawn Mower.....Some time in the future
What's the current rating of v1.5 of the Vruzend caps?
Nice Job for your upcoming V2's 👌🏽👍🏽
One other thought is how about buss bars in 3 hole, 4 hole for 3P and 4P usage. As add-ons to the kits.
V2 looks great! Can't wait :D
Nice! I am going to order some and give them a try. Thanks for the video!
Sweet!
I haven't gotten around to ordering my kit yet, and now it just got better.
So, do I wait for the V2 to show up.
Hmmmmmmm
Decisions, decisions, decisions.
It will probably be August or September before I order. Might just get the high power.

thanks for supporting our troops.
Brilliant product. Will have to give it ago.
Would love a set of the HIGH CURRENT Ones!!!
Looking more attractive with the copper, your getting more of my attention . In the future do you have any plans for a kit that we could use on larger batteries such as the 20700
Or is there a logical reason besides bigger battery that I haven't seen any battery packs with larger batteries
Love your diy battery book looking forward to building a battery
cool, can't wait to get started, b ordering v2 soon
Nice job!! Saludos from Argentina
Good to know!
Douh. Just ordered and new upgraded versio has come out. :D
When did you order? We've actually been shipping them already for a bit, so you might actually be getting the upgrade.
Nice video bud hope the new vruzen are better than the old ones. I have ordered althow i havent resived them yeat so i really need a video for a 60v+ or 72v triangle battery.
Glad I found this video, these look really cool.
this kit is perfect for a guy like me
32650 would be awesome too! Unfortunately the demand would be small.
How long do you think we will have to wait for 20700 or 21700 batteries to become the norm for ebikes. I will be building my own battery but preferably with larger capacity cells
A few years ago I built my first ebikes 6months later a better more stable motor was released of course I had to upgrade
Now my gut tells me 18650 cells will be a thing of the past soon I don't want a repeat my motor dilemma
Looking forward to building my custom battery
I hope you are still giving out free books . It's time I make a Ebike over the 60cc 2 stroke's that always brake down
Great! I'm looking forward to building high capacity power packs for high speed, off road ebikes!
Sounds fun!
WOOHOO! I'm excited!
Awsome, I think I will use this on my coming project :)
Good job. Love your videos
Hi I would to get your battery build book. I just found your company tonight. Great videos.
Great improvements!
Do you know when the 2170 cells are coming out and are you going to make caps for those when they do
Great stuff, looking forward to what develops!
Thanks Brian! How'd the solar boat go?
We had a good effort by the students, and are working toward next year's continuation of the project! We did end up with splits in most of the caps from our sets, so I'm glad to see in the next generation they are both more robust plastic caps and spring terminals are capable of carrying more current too.
that is awesome work guys love all the good ideas keep up the good work.
These look great! Nice job!
What about a ball and socket in place of the dove tail? Then its a snap to combine then.
Very cool! I have read a rumor that these kits work mostly with new batteries; how well will they work with recycled batteries? Thanks
Fantastic updates, I am looking forward to making a large order in coming weeks. What is the exact diameter (width) of the version 1.5 caps when they are connected? Let's say two connected?
how about making holders for 26650 cells as well though not as popular they are used.
Very interesting. I'm looking for a kit to build a car battery?
Like some of the other Ytubers on here when building a battery using 18650s they talk about fusing the cells, how do you/would you go about that in using this kit? Im also looking more towards power wall cells instead of powering transport. I like this idea because of my lack of soldering skills.

4s10p ?
Why do you need to have 4 bus bars between the parallel? Are not the series already connected so you would only need one going to each p?
I see you now offer black caps. Since you apparently also have red caps, does that mean we can order kits with equal numbers of red and black caps?
Good improvements on v1.5, and v2.0 should be good too. BTW, what is the rated current capacity of the v1 & v15 caps?
Great upgrades
