Wow! Michael I've been looking for person with your knowledge for a long long time and I finally following you. You are awesome. I'm 80 years old and I'm really excited with E bikes and I want get one. I've been watching all your videos and I want to thank you for all your knowledge and it's really been helping me out and I'm about ready to make the move to buy my first E bike. Thanks again, Roger
You're a real inspiration Michael. I fell into leftover ebikes and for the last 3 months all my time has been learning all I could about battery building cause the most recent acquisition had burned 3 battery packs and a charger in less than 50 miles of use. Just put 10 miles on the new pack built from batteries salvaged. So far, so good. I'll be looking for all your videos.....
Great video, very useful info about the e-bike replacement battery, charger and e-motor. I ride since 2023 spring one of the best loaded and most affordable e-bike - Heybike Race Max 48V, 12.5Ah, 500w hub motor, 3 pedal-assist levels and throttle, 7-gears Shimano, handlebar adjustment. For only around $500. Just so you know, I’m not in Heybike business relationship, just online conscience senior buyer on limited fixed income, sharing my own experience. Sure, I enhanced the lower-tube controller & battery attachment by using triple bob cradle, changed the grips with Egraon-4 for more anatomically-correct handlebar handling, and etc.
This is great that you share some of your source vendors, Micah. It helps add some credibility to suppliers unknown to the noob who is taking a gamble by just blind trust that the sources they choose are honest and fair. Thank you.
Hi. I like your videos and many are kept downloaded to watch offline. I need a help and if possible please make a video on this topic. I am working on one project to replace motorcycle battery with lithium battery. This are used in harley Davidson. I can make the battery pack, but worried about the bms. Which bms to be used, because in the description of online site its written, input voltage should not be more than 13.6v and in motorcycle the rectifier will give voltage of 14.3v, also the bms should support more than 30amp. I had seen few videos on this topic but not mentioned about bms. Can u please help
Can i use the NCR20700B cells without having to change anything else ? The voltage seems to be the same, the dimensions are just slightly bigger so the bms and controller should work the same ?
I would love to see a video about a solar charging setup that would fit in a set of pannier bags, maybe direct charging rather than having another battery in between.
Hi I have ebike model MATE X-750W. Battery 48V/14Ah fail. Battery voltage 42V -when turn battery ignition key to ignition position-drop to 0V. What can i do?
Hope to get a battery from them one day. How does figure out which battery would be an exact fit for the Rad City Step through. I see below Jeff is asking same question. I would like a second battery but just can't see paying over 600.00 after shipping. Thank you.
I have been ur fan. I am working and searching to convert gasoline bike to electric. U are in bicycle only? i have some question regarding the conversion process. I confused which motor is used, hub or engine motor. I neef 60-70 km\hr speed. Then if i used 3000w motor in72 v with 3000 rpm, can i get that speed? please suggest me.
Good vid! I am busy with cheap 18650 cells to save old makita drills, lamps, flashlights etc. Now converting a dirt bike for the woods. starting with 48 volt for low speed travel. ? where do I find a reliable motor ? or should I go higher voltage ? looking for range not speed and possible backup power. thanks.
Hi, very interesting stuff. I love to DIY. But am new to ebikes, I've made a few adjustments, but would like to know more about the battery and electricity side of things , glad I found your channel 😀.
I have a 750 watt geared hub drive that peaks out at about 18 mph. Is there anyway to bump it up a little using the adjustment feature on the little dashboard?
Would old but barely used 3 fazed moters work? I’ve not got a clue about electrics but I know I’ve them same moters all are bigger but not all the same size ,but lots are just a little bigger. Could I use one and could I use moterbike batteries?? I’m sorry I’ve so lil info I just know the moters are 3 fazed moters and I tink 2 faze. I don’t know what faze even means eitherways I’ll be making or buying so your info I’ll need 👍🏻and tanks for the other parts links and keep tem coming 👌🏼💯
I have a question my battery will no longer charge up to 42 volts it's drop down to about 39 volts at full charge is this a sign the battery going bad?
question: I got a 750W motor with a 48V battery. the motor is installed on the rear wheel. I was thinking of adding a motor to the front wheel. What would be better in terms of speed - having both motors hooked to the same throttle or separate throttle for each? I'm guessing the latter would probably cause the motors not to be in-synced which might increase drag (?) the follow up question is: should both motors run on the same battery as well?
Hi Micah. First things first I would like to say thank you for all the informative videos. I would like to know if you could do a updated video on saving $$$ on purchasing ebike parts?
When running series parallel stacks wouldn't it be important to break up the parallels two bottom balance the batteries and how would that be done without having to put a bunch of wires on the pack? With the charge controller take care of that and a high-quality charge controller?
When choosing a solar panel, look for a panel using SunPower cells. They are tested to be the most efficient cells on the market. AllPower brand uses the SunPower cells in all of their products and you will notice a huge difference. Combine that with a GVB-8 and you will have a ebike solar charger that will actually make a difference.
That was a great video. I recently bought an ebike and I am addicted to ebikes. It looks as though you have the information that I have been looking for. Thanks...
Great info! I realize it's a couple years old, however still reliant ! Navigation needed for nubile s like me ! Building a 3 power bike cruser. 48v / 1000w front hub.. Four stroke 38 cc rear friction drive with springer forks .
I bought a Vruzend kit and discovered that some of the threaded studs on the caps stick out less far than others. I assembled a pack and found it impossible to fit more than 2 of the provided metal strips on a terminal. The thickness of 3 strips does not allow the nut to fit on. Did I pound the caps on the recycled cells too hard? I used the block of wood as you describe. Was it me or is there some irregularity in the caps?
Thanks for the video and info. I have a BionX 350 watt, 36 volt conversion kit. About10 years old. Battery is no longer working. Bronx. Is no longer around (as far as I know). Any ideas on how to match a generic battery that will work with my bike? Battery fits in a carrying rack on back of bike. Motor is rear drive. Thanks
Hey Micah, i found a 36v 10Ah Li-Mn battery that comes in one of those frog style enclosures. Is that chemistry efficient like all Lithium batteries or should i avoid it? 36v 10Ah are the specs i need.
Yeaahhhh super welcome to share your solar panel projects here mate!!! People will love to learn new things and yes they're totally related! We have been charging our eBikes at work with a mobile solar panel... so good it really makes sense!! =]Solar panel POWEEEEEERRR hahaha
What would you like to know about solar power ? We've been off grid for close to 10 years now, and are finally up to using around 20kW peak worth of panels, several MPPT charge controllers, and most recently Nickle Iron( Edison style ) cells. We put about 200A into the batteries at 32v most days( mid day ). Yeah I know . . . not the 20kW you'd expect ;) That's the way solar works. Do the math on what you think you need. Multiply by 3, and then you *may* be starting to get close to what you really need ;) Making a portable ebike charging system from solar, is what I'd consider a waste of time. If stationary, yes, that would work fine. Problem is, for a pack that's say 52v and 10ah. For a C5 charge rate( 5 hour complete charge ), we're talking you're going to have to push ~104w. For a portable solar charging system, that's not going to be very practical to carry around. Of course, that's assuming the batteries are completely empty. C10 could be fairly practical, but at 10 hours, you're probably at best going to just be doing minor battery charging maintenance. Maybe something slightly better than brake regen.
I do not have as much experince as you when it comes to solar power but ive done quiet a few months research and had a little play and building my own system because since i was a kid i have always wanted to generate my own eletric. Down side being a kid not got the money and no internet back in those days. I agree with you about about what you say about portable charging and 2 years ago there was a young lady (can not remember name) cycled across America cover just over 3200 miles and she had a trailer with solar panles on it which charged the bike as she cycled on here eletric bike. The battery never got below 60% charge and she did it make people aware of mental health and a few other things basically charity type work. No point me doing solar for eletric bike as would have to go to another country to make it worth its while.
Really interesting.I got am ebike made by Kalkoff and the battery is dead now. They want 700 for a new battery and 150 for a new charger. Was wondering if it can be converted to take any battery?
So the battery supplier does not supply the 3500mAh 18650GA cells? So if I wanted to build a 28AH Triangle battery 14s8p, I would need to find a different supplier of the batteries? Also, Micah what is the most powerful triangle pack you can build? Thanks
I have a question I'm having a tough time getting information I can understand on. I don't know a lot about batteries, but what I have seen seems to point to a lot of advantages using LiFePO4 chemistry, yet I see very little little available in e-bike discussions. Why?
I'm trying to build a 2wd with 36v 500w motors My broblem is that the front wheel is 24 inch and the rear one is 20 inch Can you please explain how can i make the motors run at the same speed Thank you very much
Thanks for the headsup on Aliexpress and the 11/11 sales! I'll for sure use your links for battery buys this November. Where do we learn about controller/display options, Adding 2nd battery, front hub motors, and other cool stuff? Solar Panels keep us powered up for off-grid camping and riding! Better than noisy gasoline chargers...
Solar is a great idea. I met some people ecycling from Europe to South Africa with portable charge solar panels. Great for wild camping and ebiking....but how to do it without heavy panels?
Iam also a treasure hunting metal detectors and have hit a few good licks. Nothing big .I dont have a job I get 1600 bucks a month my house is payed far and iam remodeling it but not in no hurry .can you point me in the right direction to get ebike conversion kit. Thanks
Hi. Do you or anyone have 18650 and 21700 cells you can recomend? Im gonna build New battery bank to my e scooter. I wuld like minimum out charge A to be 10A. But every cell i find cost around 10-12$ and i need minimum 140 cells. Whot to do? Whot to buy? I have the room for 21790 cells so wuld like that, but not if it's way more expensive
Thanks for the recommendations. Are UnitPackPower's batteries safe? They claim no tax on items? How can they ensure that when it's up to customs to charge import duty/tax?
Hi Mike. I got a battery from Aliexpress lately (but can't use it because I am waiting for the motor). My question: How can I check the battery condition? How do I know if the battery was not used before? Is there some diagnostic tools that i could use at home or do I need some special equipment? Cheers
For those of us new to ebikes, how easy is it to use an after market charger on a standard ‘shark pack’ battery? Also there are all sorts of stories warning that charging should be done in ‘ammo boxes’ etc. because of the risk of fire and explosion. Could you comment please.
Trouble with being in uk is vat ,and custom charges .makes a cheap buy not worth it, as for batteries I’m waiting on the new graphene battery’s becoming more available, they will be a lot lighter ,faster to charge ,and last a lot longer.
Hi John I am in the uk too. I was wondering if you can change the battery to fit the existing motor on the Ebike? Kalkoff want 750 for a new battery and 150 for a charger,
People talk a lot about mid drive and hub drive. His dose a side mount motor compare? I️ am trying To build a e bike as cheap as possible. I️ intend to use a side mount and led acid battery. Is this a mistake?
Great vidoes would like your books how do i get them all for free ? Do amps make your battery last longer the higher the number and how do them battery packs make this work
Great stuff, Micah! I'll definitely check that sale out. My 1st conversion comes ALIVE today and I am so stoked. Your channel has been a Godsend because INFO is so critical and you sharing your experience is invaluable my friend.Thanks again and please keep up the good work.
I am not sure about getting things from China because some of the things on eBay say that there may be a import tax the I will need to pay over the price of the parts! Can you tell me what kind of import taxes there may be and how that works!
Great resource! I'm in San Francisco and we could use a lot more Ebikes here. All new to me, what should I consider when designing a bike for our step terrain? Thanks for the channel.
My home made electric bike just died the first time I took it out in the rain. I could really use your book. Thanks for the videos. I'm super excited about the deals you mentioned. Would you please make a video on hiding purchases from your wife?
The bike dried out and is back running again. Also I tried to order the 48V battery you have a link to but I haven't ordered through AliExpress in a long time and they refused my card. I'll have to plan ahead next time. Thanks for the recommendations and information keep up the good work.
My sealed lead acid battery is 7 years old just did half charge #400 going for 500 on The E-Zip Trail-Z all original . Payed $399 on Target.com for the bike with battery. Always charge right after riding, store in house at 70 degrees & only ride above 40 degrees & below 80 degrees.
Hi Mike, I'm just slightly confused. most ebike kits require cable operated brakes, what if you have hydraulic brakes as per my Giant mountain hardtail? very informative videos by the way, cheers Jonny
Glad I found your channel. I have a e Bike and the battery has died after a yr old and because I bought the bike used they are not covering it under the two year warranty. So hopefully can find a second battery and your channel can help educate me. Also very interested in solar power. This is the first video of yours I have watched but sure will be streaming more to my smart tv.
Hi Micah.... DIY Lithuim Batteries has been a source of inspiration for building batt packs. Very informative. Very nice read! would like to know whether spot welding is better than soldering?
Thanks for the heads up Micah! Hope you get a chance to try and and review the Tongsheng TSDZ2. A DIY mid drive with torque sensing. Seems to fly under the radar to the more popular Bafang motors.
Wow! Michael I've been looking for person with your knowledge for a long long time and I finally following you. You are awesome.

What a fantastic tip sir!! I will use it for the next 11.11 !
question:
I got a 750W motor with a 48V battery. the motor is installed on the rear wheel. I was thinking of adding a motor to the front wheel. What would be better in terms of speed - having both motors hooked to the same throttle or separate throttle for each? I'm guessing the latter would probably cause the motors not to be in-synced which might increase drag (?)
the follow up question is: should both motors run on the same battery as well?
Hi Micah. First things first I would like to say thank you for all the informative videos. I would like to know if you could do a updated video on saving $$$ on purchasing ebike parts?

Hi! Charging battery with CC CV charger while controller is also connected can kill the controller?
I bought a Vruzend kit and discovered that some of the threaded studs on the caps stick out less far than others.
I assembled a pack and found it impossible to fit more than 2 of the provided metal strips on a terminal. The thickness of 3 strips does not allow the nut to fit on.
Did I pound the caps on the recycled cells too hard?
I used the block of wood as you describe. Was it me or is there some irregularity in the caps?
Do you have any information about duel hub systems 😎
I don't find any specific measurements for using shrink wrap, like 13s 4p would need?
Depends on how the pack is assembled. You need to measure the largest circumference of your pack and size it to fit that "diameter" of shrink wrap.
Hello Micah

How do I know if the battery was not used before? Is there some diagnostic tools that i could use at home or do I need some special equipment? Cheers
multimeter. if you don't know that, maybe you should get a professional to do it
For those of us new to ebikes, how easy is it to use an after market charger on a standard ‘shark pack’ battery? Also there are all sorts of stories warning that charging should be done in ‘ammo boxes’ etc. because of the risk of fire and explosion. Could you comment please.
Can I buy 18650 singles to replace bad cells in an old battery pack?
yes
Trouble with being in uk is vat ,and custom charges .makes a cheap buy not worth it, as for batteries I’m waiting on the new graphene battery’s becoming more available, they will be a lot lighter ,faster to charge ,and last a lot longer.
Hi John I am in the uk too. I was wondering if you can change the battery to fit the existing motor on the Ebike? Kalkoff want 750 for a new battery and 150 for a charger,
Apparently any item over £16 purchased outside the EU will be charged customs, VAT and £8 for the post office.
People talk a lot about mid drive and hub drive. His dose a side mount motor compare? I️ am trying To build a e bike as cheap as possible. I️ intend to use a side mount and led acid battery. Is this a mistake?
Excellent tips. I looking at 48V bottle packs to run on my smaller e-bikes.
I just added that 48V 14.5Ah shark pack to my cart. :-)
Great vidoes would like your books how do i get them all for free ? Do amps make your battery last longer the higher the number and how do them battery packs make this work
Sho what is the difference between the bike kit you referenced and the decently rated kits on eBay that range $200-$300?
Mid drive vs hub motor
EbikeSchool.com. Thanks for the quick reply! I'm new to all this and trying to plan my build. The links are very helpful.
Great stuff, Micah! I'll definitely check that sale out. My 1st conversion comes ALIVE today and I am so stoked. Your channel has been a Godsend because INFO is so critical and you sharing your experience is invaluable my friend.Thanks again and please keep up the good work.
I am not sure about getting things from China because some of the things on eBay say that there may be a import tax the I will need to pay over the price of the parts! Can you tell me what kind of import taxes there may be and how that works!
How much ah (ampere hour ) I cn put in 48v Lithium ion battery under ₹30,000 and ₹40,000?
Great resource! I'm in San Francisco and we could use a lot more Ebikes here. All new to me, what should I consider when designing a bike for our step terrain? Thanks for the channel.
How can I connect 2 motors in one motor controller?
My home made electric bike just died the first time I took it out in the rain. I could really use your book. Thanks for the videos. I'm super excited about the deals you mentioned. Would you please make a video on hiding purchases from your wife?
Keep the stuff wherever you keep your tools. My wife never looks there ;-)
The bike dried out and is back running again. Also I tried to order the 48V battery you have a link to but I haven't ordered through AliExpress in a long time and they refused my card. I'll have to plan ahead next time. Thanks for the recommendations and information keep up the good work.
My sealed lead acid battery is 7 years old just did half charge #400 going for 500 on The E-Zip Trail-Z all original . Payed $399 on Target.com for the bike with battery. Always charge right after riding, store in house at 70 degrees & only ride above 40 degrees & below 80 degrees.
It´s great that you share with us your sources, when buying for china you never know whose vendors you should trust.
Thank you!
Thanks for sharing all of your knowledge about e bikes
Hi Mike, I'm just slightly confused. most ebike kits require cable operated brakes, what if you have hydraulic brakes as per my Giant mountain hardtail? very informative videos by the way, cheers Jonny
Glad I found your channel. I have a e Bike and the battery has died after a yr old and because I bought the bike used they are not covering it under the two year warranty. So hopefully can find a second battery and your channel can help educate me.
Also very interested in solar power. This is the first video of yours I have watched but sure will be streaming more to my smart tv.
Hi Micah.... DIY Lithuim Batteries has been a source of inspiration for building batt packs. Very informative. Very nice read! would like to know whether spot welding is better than soldering?
I can never figure out how to order on aliexpress seems like u can only buy bulk
LOVE the videos! Just got my DIY BOOK! CAN'T Wait for future videos. Hope to get your other book soon.
just found your Utube channel was looking for info on different types of batteries. and then purchased your DIY Lithium battery book on Amazon. thx!!!
How do you pair a charger with a custom battery pack?
Excelent piece of advice!! Is it too much to ask where i can buy large amount of 18650 cells?
Have you found a planetary gearbox in the 20:1 range that is affordable?
Love your videos and the useful information they provide. A lot of the information is applicable to a lot more than just e-bikes, Thank you!
Can you tell me if the Ah Hailong Shark battery will fit the 2019 Rad Power City Bike?
Is it better to buy a factory built battery or to build your own? Comparing price, quality, battery life, etc. Thanx for your informative videos.
Thanks for the heads up Micah! Hope you get a chance to try and and review the Tongsheng TSDZ2. A DIY mid drive with torque sensing. Seems to fly under the radar to the more popular Bafang motors.
