A true work of art, a think of beauty and passion. Thank you Pavel

Hey Pavel! Just wanted to say THANK YOU!!! This kind of video is exactly what I wanted to see. I appreciate how you detailed every element and every action you took. I am learning so much and will be constructing my own pack soon. Happy building!

This is what I needed to watch to fill the gaps in my knowledge of battery pack building. Excellent video!

This is like a cooking show, for batteries. Absolutely incredible value!

Tremendously helpful. I appreciate your slow deliberate pace covering all the bases and I love how you dealt with the hot solder iron heat issue. I also like how you compartmentalized 6 batteries at a time making the process simpler to understand. No missing camera angles, either. making you wonder where that wire went! Thank You!

Vote for Pavel !! Great video!! Learned a ton. Saved me from going BOOM!!

THE BEST PERSON ON THE PLANET.GOD BLESS HIM.SUCH A TICHER.HONEST.

Guys! Sorry for the delay but it took much longer to upload than i expected. Took me over 3 months to build and film so hopefully you will appreciate the detail and effort. Enjoy and please comment so i can get some feedback- good or bad. Enjoy! Build safely 🙏

Bravo Pavel! Extremely helpful, extremely detailed and overall best Esk8 battery vid I've found on RU-vid.

I used to work as a PVC plastic welder for a fabrication company in Louisville, Kentucky. A guy that I was training under said measure twice before making cut and tack it together first and double check blueprints before welding it together. 🙂 I like your well thought out plans to try and make a good safe product. 👍👍

If anyone were to buy one of your batteries, they could rest assured that it was built in the most high-quality way possible. amazing work.

Absolutely beautiful build! Only 11 minutes in and loving it! Subbed

This is by far the best battery build video on RU-vid. I have watched so many and spent countless hours watching others, and yet I have learned so much more watching this one alone. The detail skill and care, that you so helpfully share is superb. Thanks largely to you, I now feel confident to begin my first ebike battery build. I will of course watch all your other videos with interest. Thank You for sharing your knowledge, and the help that it gives.

My Man!!! Before one year i see your video for first time... I didn't know ANYTHING about batteries (only AAA to my clock 😁).... Till now i had make one 60v 20a battery and allot of 2s, 3s, 4s, 5s... I write now to thanks you for opening the door to a new MAGIC world....!!!!🙏🙏🙏 From Greece 🇬🇷 with love and Respect!!!!👏👏

Your care to detail is a great example for the people learning. always a great video !!

Terrific. The best organized, filmed, comprehensive, likeable, informative video on ANY subject matter I have seen since RU-vid began. We are all lucky that there are folks like Pavel Garmas tto have the know how, the patience and the organizational skills to make this video. Congratulations from Florida...

This video is by far the best board building video I have ever seen. You're a star, sir.

Thanks for taking the tie to make this, best and most detailed I have seen, yet.

Dude, you are my new best friend, watching every second of your video - LOVING IT

Thank you so much for making this video. I feel more confident now to, maybe, build my first pack someday. Cheers

Wow a child can build watching your vid. Thanks a lot it was very well done ⭐️⭐️⭐️⭐️⭐️

You are amazing and a true pleasure to watch and learn from your video's! Right on Pavel good job!

Simply amazing your video! I am a Physics teacher here in Rio, Brazil and responsible for the Solar Trip educational project, in which high school students will design and build a solar bike for a 2500 km journey. Your video is a real lesson on how to build a battery. Thank you very much. All the best!

Loved watching this, now able to build a battery . Thanks 🙏🏻 love from midlands

Unreal video. Explains alot. Thanks for putting it together. Helped me alot .

Brilliant video pavel best battery build I've ever seen thank you for sharing

Best battery build video on the tube. Love ya work Pavel ✌

Awesome board one of the best builds on RU-vid to date

Your dedication to us and these videos is amazing. I can tell these boards get your best work.

Thank you for this video, I would LOVE to se others take advice as you do, you just seem to love to hear other’s opinion on your builds and improve upon them! It’s just lovely to see that the earth still has people that just want to make things right and put the proper time and effort to make the final product just amazing. I think your detailed battery pack build video is just an amazing video that more people should be watching and learn from it. I’ve seen a tone of battery packs that are just awful, but you really made me happy wen I saw that there are other people that care about safety just as I do 😊 Thanks for the video!

Hey Pavel! WHAT A NICE KIND HUMBLE MAN YOU ARE Just wanted to say A BIG THANK YOU This is by far the best battery build video on RU-vid,👍👍👍

very interesting job Pavel. Thx for keeping us all informed and updated dud. You´re doing an excelent job !!!! Cheers !!!!

we need more guys like you thx for sharing this great tutorial for creating diy battery packs ,,

I watched this the second time b/c this is what I want to follow and I notice that you followed the tips/suggestions from your readers for more improvements. Very cool!

Thank you Pavel! Great video! 💪🏼

I am highly impressed about how detailed and very informative your videos are. Great job 👍🏼👍🏼 !!

This is a real tutorial. Thank you.

That’s how I feel I made a new friend today. That was so informative

I really enjoy this style of video. I watched it in parts and it was awesome! :-) Very educational and perfect for fresh ppl like me. Thanks a lot mate! Keep up the good work!

Love the way u Explain 💕

thanks for the video! in a couple weeks time i'm going to have to disassemble my 10s4p pack to make it lower profile from a 4 stack high to a two stack configuration since i ordered the wrong pack for the battery housing.

The best video I learned about drums. very good, congratulations, here in Brazil there is no video with much detail showing everything. congratulations greetings from Brazil

This is an awesome video! Thank you. I´m pretty experienced in building batteries, but watched it till the end anyways. I love how you transfer not only the technical knowledge, but also the "spirit" of good designing and engineering, of keeping calm and stay focused, and stuff like that. Thumbs up!

Nice job , thank you. I like how you made it low profile.

Thank you so much for making this video! I have been wanting to try and build my own pack for a long time but its pretty intimidating, you did an outstanding job of covering everything especially with the camera angles, I can't tell you how many times I've seen videos where they explain stuff but don't show it properly and it was a waste of time watching. Thanks again hope you keep making these great videos!

nice vid helped me build my ebike battery made 4 36v 14 ah packs and have two connected in series at a time

fantastic video! exactly what first time diyers are looking for!

Very informative.. I'm building my own battery in a few weeks this has helped alot. Thank you

Great video Pavel. Look forward to the next one.

very impressed, it's a really good job, super well explained and in addition it's great to see that you are open and that you take into account the opinions in the comments. It's great!!!

Thank you sir, I learned a lot and lovve the explinations. Had no idea of hte BMS system set up and it was pure vodoo until you expoained it.

Absolutely brilliant video so in depth for a complete novice like myself you should consider teaching as you are a natural person to be able to explain how things work 👍👏👏

U have all good tools at ur workbench👍(perfect demonstration)

This video is SOOOOO Good! Great Job and Thank you!

Simply awesome video. Thank you so much for the detail and the sharing of your vast knowledge. Going over the basics is a great help for t hose of us that think we know what we're doing. Can't wait to see your other videos. Thank yo once again.

This makes me feel like I can build a battery too! Subbed

Perfect video mate, true professionals make it easy to understand and you did just that 🎉

Really helpful. Can you tell me what would happen if the two packs touched each other down the center of the board when your building the battery?

YES, Dude i was looking for a video like this for months. I'm building a 96v Adult "Big Wheel"

SUPER CLEAN awesome man.

Excellent video and yes I did learn something I was dreading building a battery pack not now you have put the process within my skills and abilities. Thank you so much I have learned a lot, Jay

I guess I have 2 best friends named Pavel now!!! My mann, FINALLY, someone who breaks this process down in an easy to understand format! I watched your other video on the block but this was the one for me and took all confusion out of building a battery. On top of that, I am going to use Molicel's so that made it even more confusing, UNTIL NOW BRO! I can finally, confidently build my battery for my bike. Even though it may be apparent, it's worth noting that you save ssoooo much building these at home. God bless you 🙏🏽 for taking an extraordinary amount of time for the rest of us who want to learn. Let me be clear, I have watched 20 videos and none of them were remotely close to what you've done here! Not even a contest. Please keep doing what you are doing!!! The adding of bms tabs, was huge as well. I was counting packs backwards, nownI just do the P 1st, then how manynof those for my series. Just can't thank you enough as you can see lol 🎉😅

Finally got round to watching this and it's pretty awesome to be fair mate. I'm not planning on building my own pack soon, but I will be getting one made early next year. This video helped me a lot with little details I wasn't sure about like a suitable BMS. I never really understood BMS' properly at all actually. Now I know for sure a charge only BMS is perfect for what I need and a smart BMS is very much what I need as I'm really interested in monitoring the health of the individual cells. But if I ever do make my own pack, this is the video I will be following. Much respect!

Great video. When I build my batteries I would use masking tapes to cover all the connections that I am not working on to insure that nothing accident touch and could short the battery. I once dropped a strip of nickel on the battery and it caused a short.

Excellent video man you explain everything like a pro, thanks for such an informative vid, 😎🇬🇧

Excellent video Pavel. Im attempting to built a battery pack just like your .

Dude you are the bomb! Your channel is a treasure trove for my project. This video is the best for anyone trying to tackle a "light EV" project on their own! Also you're a legend for responding to so many comments on a 2 year old video.

Love the video, thank you very much for making it. I learner alot from it

What about external thermal insulation vs heat dissipation of the cell electronics? Does the bricks embedded in silicone resin do a better job as fire retardant?

Do you think anything could be improved in this video or similar videos? Was it a good idea to keep it as one Tutorial? Cheers guys.

You are a Master this is pure électronic arts. You really got talent 💪👍😍

Great explanation.

Very nice video, extremely well explained procédures. Thanks

Thank you for this video it helped me a lot keep up the good work!!!

EXCELLENT TUTORIAL IN EASY TO USE AND FOLLOW FOR EVERYONE. A BIG THANKS TO YOU. I have been converting Mountain Bikes to e Mountain Bikes for the last 3 years. I have always been buying high capacity batteries from China. 48V, 32.2 Ah in various shapes to fit into the MTB frames. This is a very detailed instructions. I will be building my own battery packs to form the exact shapes that fits inside my MTB frames.

Thank you so much for all those tips

I am very very thankful for your help and products spot

Definitely a battery you can be proud of. It was great to see you soldering properly too and the reason the solder alloys better with the nickel when you sand it, is because you've removed the surface oxidation.

Watching this for the third time now, with a notebook, have the kweld completed and calibrated, tested.

Wow this is what I've been looking for.

cheers from greece thank you very much

Thank you so much this is truly an amazing video

Thanks for an awesome build tutorial! It covered everything I had questions on about building these packs. Near the end, just before you put the heatshrink on, what is that extra connector coming out of the end of the pack (at around the 1:38:15 of the video) ? I didn't see it there in the prior shots when the pack was still in the casing.

Nice job man, honestly. I was nervous to make a battery, but after seeing this video, I’m pretty sure I could take it on. Thank you so much for being so passionate about this great hobby and providing amazing information to everyone.

Cheers mate !!!! Thnks alot for all of it.

Well done that was brilliant

Please can you tell me if I want to make 7s3p all the voltage is the same 3.6 but there is one that is 3.9 is that okay? Thanks you

This is so satisfying ❤

Fantastic video ❤ ASMR for electronerds 😊

What's your spot welder's yellow electrode holder called? Trying to find one but can't manifest the right keywords.

Excellent , very cool to share with us all that tips . You”re a master in DIY , you are always looking for the perfection and I like to watch your tutorials for it , they are always complete and precise but staying accessible for the beginners.Perfect ! 😉👍

Hi Pavel, Just amazing vidoes, love your work, just wondering what size shrink wrap did you use?

Thank you so much Pavel - I was getting discouraged about attempting my first build but the way you illustrate exactly how electricty flows from pack to pack down the circuit was exactly what I have been missing and now I FINALLY get it! I am excited for my build again (18s6p Flux/lacroix monster build!) wish me luck brother - Cheers! -

Very nice video, you are the best teacher. Respects dear

Man this video is one of the most interesting ever, congratulations 👍
