When you turn on your mobile data, and use last Megabyte of your data just to watch this awesome DIY, then you know this is the best DIY tutorial on internet! Great work, keep on going :) And I want to start building my own E-bike so I am glad that I have found your YT channel where I can learn anything about batteries and e-bike :) thank you for your contribution :)
hello, I have only just been turned on to electric bikes, I am still blown away daily with stories and pics of new projects, positive and all good in the bike world. now because I am on a budget I have found it to be an expensive hobby that I found I personally couldn't afford, so when I first started to see some of your battery builds frankly it gave me the confidence to eventually attempt my own fantastically reduced price battery builds of my own and after months of umming and ahhing finally, I have the confidence through knowledge to happily build any cut-price battery pack that I may need in the short term. I think it has to be said that your youtube videos are a service. I will be buying both books as I am interested in the two titles that I know of, so thanking you very much stew.
Dude, you and your videos have set me on the path of (slowly!) converting my recumbent cruiser into an e-'bent. I've even got your first two books on my shelf, now I'm just waiting to get the parts in hand to put the knowledge to work - and I'm seriously considering your solar book so I can adapt its concepts to a bike trailer. Thanks so much for sharing what you know and making battery pack assembly more accessible!
Your channel has helped me sooooo much. Just wanted to thank you for all the good info and confidence to build a DIY setup instead of paying for less performance. One thing that I haven't really seen and genuinely hope there's enough material for you to make a video about, is the waterproofing of these DIY setups. I live in Flagstaff AZ and we get the monsoon season and I would absolutely LOVE your brilliance and opinion on the safe water resistant method of approaching these projects. Thank you again!!
Thanks Jeremiah, that's why I do this, to help people achieve what you did! I'll try to make a video on this subject. The summary is drip loops, making sure wires exit components down towards the ground, silicone caulk things or add weep holes at the lowest point on enclosures (since its hard to keep something 100% sealed, its often better to have an opening somewhere for the water to get out instead of trapping it in).
EbikeSchool.com oh awesome! That would be amazing. Thank you for the info in summation. Stoked for you and your products taking off, keep it up brother!
Congratulations on V2, and your drone shots are really terrific!. BTW, I bought a new battery for my new kit from unitpackpower, (I can never tell if using your links works), it's a 36v equivalent to your mighty mini in that new kettle casing, love it! Thanks again, Micah, for all of your help and videos!
I love watching your videos and I intend to get a copy of all three of your books soon. Thank you for putting out all the free top notch information and I am so looking forward to this electric revolution.
The cap system is interesting and seems like a great alternative to welding or soldering. If you were just getting into DIY lithium batteries, they would save you some money on soldering/welding equipment.
how do you calculate a theoretical range or how long a charge will last you? Also, is it possible to connect two of those bottle type ebike batteries together to double the Ah?
Thanks for these guiding videos. I have learnt a lot and am still learning from your channel. Helped a lot in making an ebike for myself. It has a 24v 250 watt hub motor and a 7s9p battery pack that has 18ah capacity and gives me a very long range. All thanks to you. Keep making such awesome videos.
I am not understanding how you are connecting the balance wires. Do you connect them to every single cell? Or which cells do you connect them to? Also, which part is used to charge the battery and which part is used to power the bike for example?
Nice build. I am thinking to put that entire pack into a plexiglass box in a 10s4p or 3p config and strap it under my board. And i totally dig the color choice
At 7:12, isn't the battery just the opposite of the diagram? The diagram for the bottom of the battery shows "+1" in the lower left, but the lower left on the actual battery is a "-" cell...
Thanks, solve the problem for me. Since most of my commuting is down to the local supermarket and back, I’m only getting a 48V 14 AmpH battery for my set up. Having a little spare for a longer ride I’m about five ampH is a help👍🏻
Hello Micah, I do have a question or four for you. This 52V 20Ah battery: What range do you get with it? How many hours does it last? What is the exact voltage when fully charged? At what voltage to you recommend recharging? Thank you for your time.
The illustration around 2:30. Did you make this manually, or was it generated? I need something to make a schematic that can be very easily understood, safety first ^_^ .
Great video. I have a basic question that has always confused me; I understand dielectric grease keeps moisture out, but dielectric grease is non conducive, wouldn’t coating the battery connections reduce or block current flow?
Can you make a video showing how to build a 10s with 5 cells in parallel, 36v battery? I’m a bit confused on how to lay out the bus bars on a bigger build? Thank you!
What is the weight of the finished pack? I’d like to see each of your battery builds on a postal scale, or similar, so I have a better grasp of its dimensions.
Great video. I would absolutely not recommend 30q cells for a 2p pack. I actually built that exactly thing, and within 2 miles the hot glue melted and I had to disassemble it to avoid a short. So dangerous lol. Be really careful with your batteries . Get some 18650 insulators from IMR batteries, and make sure your amps are high enough so the cells aren't stressed out.
Another helpful video. These mini packs look like a good option for me. If I were to parallel two of them for longer trips how would you recommend doing that if you still wanted them to be able to be separated? Also I noted some comments below and your approach to fixing issues. That is awesome! Customers always appreciate service and are willing to deal with lots of problems if they feel they are being treated fairly. Bravo.
i had a question for you, have you tried the 12volt lifepo4 batteries that i think would be an upgrade to 18650 type batteries ...i herd lots of good news on them so i was wondering have you done a review on those for a Ebike usage with those type?
do you use the BMS for discharging as well? and would it be bad not to use a BMS for discharge and just connect the + and - directly from the battery to the controller
Just learning about building batteries , can you build them into different shapes to fit different bike frame configurations , some full suspension bike don't offer a lot of space .
Great video Micah! Thanks for the upgraded kit I received! I was wondering if you have or would do a video on how to make a flat pack that’s 12s for an eskate
How will a 12v 42 cell be made would they all be paralell or would three cells be in series or does the charge controller keep all the cells at 12v with more wattage
I have seen someone using the V2 this year and saying the splitting issue as with V1 is still happening. Was thinking of these to trying a a large 28s20P pack??
The kits themselves are so new that they aren't in the book, but all of the same concepts about how to plan the battery, connect the cells, etc etc is in there. Just substitute 'nickel strip' for 'bus bar' and things like that and you're good to go. I also made a bunch of videos like these.
@@EbikeSchool Thatnks for the reply!! Yeah that's what meant, the diagrams. I just order the book from Amazon. One more question if you don't mind. I'm not an electrician so I may not word this properly. Is there any loss in efficiency with the V1.5 and nickel strips? Is one better than the other at conducting current?
Great learning video, thank you. Hey Mike, can you please make a video on how to make a 10s3p Flat battery pack to be used in a slim battery case on an electric skateboard? Thank you for sharing your knowledge.
Hi, Thx for all the info. New kit looks great. What's the max amps per bus bar for the old kit? Bought two of the old ones a month ago, they did not work well with 18650GA cells 😕 Too many splits. Plus low tolerance on the mouldings imo made construction a pita. Wish the new ones had been out then. Keep up the good work. A
Maybe it was just me or the fact that I was watching really early in the am but I’m not really sure on the difference between v1.5 and v2 other then color and tightness but it seems like v2 costs quite a bit more looking at the Kickstarter. Can you elaborate further on the differences? Maybe another video that just goes over the differences specifically?
Rishard C. - See this video from Micah where he goes over the differences and evolution of the kit: ruclips.net/video/r5LlTUiO9vg/видео.html (Hope that helps)
They line up with the V1.5 but not earlier. If your caps don’t have the Vruzend logo on top (removed starting with V1.5 to make more room for bus bars) then the V2 dovetails will fit.
I learn so much from your videos. If I build a 3s10p battery with cells rated at 18A max. continuous discharge rate, how do I compute the draw on each cell when my battery is connected to a load? Or how do I determine the max load I can place on my battery?
If I wanted to make a 52V 14S pack which had a bit more range, is there a way to add on a few cells with the Vruzend kit? The way I understand it is to make a 52v 7.5 AH pack, I would have to make it either 14 cells long, and 4 wide, or 7 long and 8 wide. Thanks!
yesterday i bought your kindle book (diy lithium battery) for looking diy 12 volt battery (about 20 amp) for my fish finder. a bit disappointed that i could not find any diagram for that application. 12 volt is quite popular for many applications so wondering if you may provide a video for us who do not know electronic, current, amps, volt stuff. thank you.
Yes, it’s an option. The insulating posts on the caps mean the sandwich plate does not contact the connections. You do want to make sure you don’t have any loose wires anywhere though.
The v2 is a good refined product now,if you can diy,a lunacycle,or radrover,pack with almost no soldering you are doing good. Now get that much promised graphene enhanced cell on the market, even a percent boost would be awesome
nice mate, im from Australia and I to say I love your videos. im looking at doing my own bike but kinda big battery. but I was also thinking about making a solar battery storage with your kits. im also getting a pulse wave gen that would be hook up to your kit once I get all the batterys. so I hope I can get one of the books to help with my projects :)
great tutorial. thanks. I run a 36v bbs01 at max 18A and I'm going to try build a micro battery for my daily commute. Could I really push something like a 25R with a continuous 20Amp rating on just 1P or would it just not be worth it. Would 2P always be the bare minimum do you think to get any sort of viable range. It would need to be good for 7miles.
Looks pretty good! Definitely thinking of trying this! I'm still trying to run the numbers and see if it's that much less expensive building your own battery (with the batteries, case/bag, BMS, etc.) compared to buy a commercial battery pack. Any thoughts?
For my model aircraft application I need ultra light batteries. I was wondering how much the lithium batteries would weigh without the casings? So lithium batteries can get like 200 watt-hours per kilo. How much do you think this could be improved if they did not have a casing? I'm thinking I can separate the conductive parts with something lightweight like balsa wood for example.

Congrats on the V2.0! Impressive copper with nickel plating, you guys are great at listening to feedback and adapting quickly.
Nice to see the V2's are now available!
Have you done a show on matching the BMS to your battery pack? Are there recommended BMS brands and models? Where are the best places to buy them? Thx
You made that look entirely too easy 😀
Awesome build.
It's what he does for a living.
Converting an 80s recumbent trike. Your videos are really filling in the gaps in my knowledge. Thanks!!
really liking how easy the vruzend kits make producing a DIY ebike battery
Your channel has helped me sooooo much. Just wanted to thank you for all the good info and confidence to build a DIY setup instead of paying for less performance. One thing that I haven't really seen and genuinely hope there's enough material for you to make a video about, is the waterproofing of these DIY setups.

but it makes the battery WAY thicker.. not a fan.
I love watching your videos and I intend to get a copy of all three of your books soon. Thank you for putting out all the free top notch information and I am so looking forward to this electric revolution.
when do you expect to have thev2 kits in stock thank you
Nice that this pack is so easy to assemble you can build it on the family couch. Love it.
The cap system is interesting and seems like a great alternative to welding or soldering. If you were just getting into DIY lithium batteries, they would save you some money on soldering/welding equipment.
It's getting better every time. Congrats.
That made battery pack assembly look so easy. Thank you. So much to learn.
I suspect I'll be viewing this video many times over the coming years. Thanks!
I'd like to see more discussion of the charge/discharge connectors, wiring for an ebike specific power connection, etc.
how do you calculate a theoretical range or how long a charge will last you? Also, is it possible to connect two of those bottle type ebike batteries together to double the Ah?
Can't wait to get a v2 kit.
Yay V2!!! Thanks for moving forward with the technology!!!
Awesome work. Just pre-ordered the 2.0 kit. Got a few projects to use these in.
Thanks for these guiding videos. I have learnt a lot and am still learning from your channel. Helped a lot in making an ebike for myself.

Those v2 connectors look swell!
Is it okay to connect all 14 wires of the BMS to a 14 pin connector and connect the BMS only during charging along with the charger?
Awesome videos. Each I watch makes my engineering and understanding more complete
At 7:12, isn't the battery just the opposite of the diagram? The diagram for the bottom of the battery shows "+1" in the lower left, but the lower left on the actual battery is a "-" cell...
Awesome! Congrats on V. 2.0 guys👍🏼👍🏼

Great video! Your cinematography is spot on!
Continuity is a bit dodgy - looking off camera in one spot:)
This answered alot of questions I had about building my own battery system for an eBike! thanks buddy
After watching this, I actually feel confident enough to try to build a battery of my own! =D
Hello Micah, I do have a question or four for you.
This 52V 20Ah battery:
What range do you get with it?
How many hours does it last?
What is the exact voltage when fully charged?
At what voltage to you recommend recharging?
Thank you for your time.
Did you get your questions answered?
@@reedcastleman105 No. :)
Gonna give these a try just ordered a set gonna try out a 7s pack …for my powerwall
I just ordered the v1.5 will test those out for my application but I'll definitely pre-order the v2.0
I was just about to buy v1.5. I'm excited to try version 2 out.
The illustration around 2:30.
Did you make this manually, or was it generated?
I need something to make a schematic that can be very easily understood, safety first ^_^ .
can you use maxwell Supercapacitors to offset some of the weight ?
could you please share the dimensions of these very cool connectors
Where can you buy the vruzend kit online?
Finally! Been waiting for this to come out!
Great video. I have a basic question that has always confused me; I understand dielectric grease keeps moisture out, but dielectric grease is non conducive, wouldn’t coating the battery connections reduce or block current flow?
Curious what material are the busbars made from ?
Can you make a video showing how to build a 10s with 5 cells in parallel, 36v battery? I’m a bit confused on how to lay out the bus bars on a bigger build? Thank you!
What is the cost savings of making your own battery V buying one already made?
What is the weight of the finished pack? I’d like to see each of your battery builds on a postal scale, or similar, so I have a better grasp of its dimensions.

Can't wait to try that kit! Good job!!
What pack did you have on your bike before that one ? Did you notice much difference between the two?
do you use the BMS for discharging as well? and would it be bad not to use a BMS for discharge and just connect the + and - directly from the battery to the controller
Just learning about building batteries , can you build them into different shapes to fit different bike frame configurations , some full suspension bike don't offer a lot of space .
Great video Micah! Thanks for the upgraded kit I received! I was wondering if you have or would do a video on how to make a flat pack that’s 12s for an eskate
very intuitive video, with little attention you can make super batteries
id love to get an e book of the battery one plz
Nice work. Looks great! This will make big power batteries much more compact.
How will a 12v 42 cell be made would they all be paralell or would three cells be in series or does the charge controller keep all the cells at 12v with more wattage
Will the V2 kits work with "button top" batteries?
Tell about bms and controllers. Can these be made by hand?
Clearly the easiest battery connection solution around!
I have seen someone using the V2 this year and saying the splitting issue as with V1 is still happening.
Was thinking of these to trying a a large 28s20P pack??
You make it look easy.... I’m gonna try it! Thanks for the video tutorial!
You really make building batteries easy :)
Is all this in your diy lithium battery book? I ordered the V1.5 kit and plan on making a 52v 25ah battery with 25R cells.

They line up with the V1.5 but not earlier. If your caps don’t have the Vruzend logo on top (removed starting with V1.5 to make more room for bus bars) then the V2 dovetails will fit.
Will the vruzend connectors fit inside a shark/hailong or bottle type battery case?
I learn so much from your videos.
If I build a 3s10p battery with cells rated at 18A max. continuous discharge rate, how do I compute the draw on each cell when my battery is connected to a load? Or how do I determine the max load I can place on my battery?
What type of solder do you use for the crimp connection?
Just use a crimper
Micah, can you buy the vruzend kit in Israel?
Can you build one with the gold batteries?
If I wanted to make a 52V 14S pack which had a bit more range, is there a way to add on a few cells with the Vruzend kit? The way I understand it is to make a 52v 7.5 AH pack, I would have to make it either 14 cells long, and 4 wide, or 7 long and 8 wide. Thanks!
How much did all the compound cost?
can you show how to make a 60 AH battery?
Is it really required to have that big air and distance between cells? I saw people gluing cells tightly togather and battery gets more compact.
If your battery is open to air, the gaps can help with cooling. If the battery is sealed, then it doesn't make too much of a difference.
Changing a cell gets pretty hairy with the glue.
yesterday i bought your kindle book (diy lithium battery) for looking diy 12 volt battery (about 20 amp) for my fish finder. a bit disappointed that i could not find any diagram for that application. 12 volt is quite popular for many applications so wondering if you may provide a video for us who do not know electronic, current, amps, volt stuff. thank you.
3s is closest to 12V, and there are 3s diagrams in the book
Forgive me if im wrong but from what i can see from your battery image setup looks like the battery has been configured as all in series wiring
How long would it last on a 48v 1000 watt motor?
if I wanted to connect 2 or 4 of these together would that work?
are you recommending to use metal to sandwich the battery pack?
Yes, it’s an option. The insulating posts on the caps mean the sandwich plate does not contact the connections. You do want to make sure you don’t have any loose wires anywhere though.
Orlando?
The v2 is a good refined product now,if you can diy,a lunacycle,or radrover,pack with almost no soldering you are doing good. Now get that much promised graphene enhanced cell on the market, even a percent boost would be awesome
Can I change out the capacitors in a 48v controller to handle a 60v battery?
nice mate, im from Australia and I to say I love your videos. im looking at doing my own bike but kinda big battery. but I was also thinking about making a solar battery storage with your kits. im also getting a pulse wave gen that would be hook up to your kit once I get all the batterys. so I hope I can get one of the books to help with my projects :)

Would you run those strips in the same configuration for a 12v 55ah used to run a 55lb minn kota trolling motor?
That is a very nice way to make a battery!
Looks pretty good! Definitely thinking of trying this! I'm still trying to run the numbers and see if it's that much less expensive building your own battery (with the batteries, case/bag, BMS, etc.) compared to buy a commercial battery pack. Any thoughts?
Really cool, I want to build a solar powered e-bike to ride around Asia, just found your channel sure it will help me loads
For my model aircraft application I need ultra light batteries. I was wondering how much the lithium batteries would weigh without the casings?
