Thank you Mikey, After finding ebikes as a hobby for an old electronics engineer, who likes being hands-on, you have given me the drive & confidence to build my own battery, all I need now is your book!
R.P. Rosen yeah... Micah is the NICEST GUY... I also have a channel my Micah’s videos are way more “educational” than my “weird” presentation style hahaa more POWEEEEERR
Thanks Micah for all you do. I just completed my first 14s3p 52.8 battery build to go with my first e-bike build. It turned out great. I've been riding it everyday and can't wait to build my next battery.
This is the first time that I've seen you I'm quite impressed I'm new to e-bikes right now I'm learning I found your comments very informative thank you
As far as City Slicker jitter, I discovered a problem with the factory tires and will do a video on it soon. Basically they have flat spots from sitting and shipping stress that makes the bike bounce. If you watch your first ride video forward camera look at the bouncing but the front forks don't move, suspect tire flat spots. I'll install new tires to test but it won't be anytime soon.
Your The MAN.... I HAVE GAINED A GOOD EDUCATION IN Battery TECH...YOUR A GREAT GUY. GREAT Video ....SHARED LOTS OF Video ON FACEBOOK...ONE DAY I HOPE TO BE AS SKILLED AS YOURSELF SO I ALSO CAN PASS The KNOWLEDGE ON....
Hello Micah! I bought a new and bigger battery for my ebike. I know a fair bit about RC Lipo batteries but not much yet about batteries made with 18650 cells. Anyway, when I removed the old battery I noticed it has separate charging leads from the discharge leads. Question: does this mean its BMS cannot handle charging from the discharge leads? The new battery that I got has only one set of leads for both charging and discharging. I measured the voltages on the charging and discharging leads of the old battery: they are the same. I want to stick the old battery in my ebike in parallel with the new battery, but that will only work if I can recharge both batteries from their discharge leads. Best regards from Brasilia, Brazil.
Hey Micah, I fell in love with electric bikes and scooters few months ago when I went to visit Tel Aviv. Great city. Question, hub or mid-drive motors. What's your preference and why?
could a three wheeled trike type bicycle have identical rear hubs of direct drive for good traction, or would that make it impossible to steer the front wheel to turn a corner?
I have a battery powered EGO lawn mower. If my battery is "rated" for a number of charge cycles, if the battery is not fully exhausted, will a half charge still count as a full charge in this number of predicted charge cycles? Am I shortening the life of my battery if I charge after mowing and not waiting for the BMS to stop the mower motor? Thanks for your help.
Hi Micah, Two years ago I built a 36v battery using new Samsung 25R cells and Vruzend caps, 10s 3p. It powered a 350 watt front hub motor on a trike. It was ideal for going around our Retirement Village. Last year I increased the size using recycled cells to 10 s 5p. Everything is working fine but the battery now needs to require recharging more frequently. Do you have any suggestions.
I'm considering building a discharge device as demonstrated in another of your videos . . . The problem is that the discharge port is a proprietary connector . . . Would it be OK to connect the discharge load to the charging port? Are the two ports electrically the same connections? Thanks, Luke Wood
What is the best switch to use in switching between 2 li-ion batteries of an e.scooter? Cant seem to find 1, I plan to use 2 batteries with different capacities.
After some research, found a way to control the temp of battery pack using W1209 controller and NTC sensor. In theory effective and cheap. I have the need to heat up the batteries in cold weather.
Yeahhh nice to see you’re doing a lot of travelling... just a quick sleep on the floor and you’re good for more haha Yes, EM3EV is by far the best battery maker, I’ve been to the factory a few times, I wish Paul (EM3EV) was allowed show some of his custom design build he does for other companies but often there’s a NDA contract. Love this Q&A video!! Please make this more often =]
Martyr4JesusTheChrist ohhh losing your channel would be heartbreaking =/ Yeah, those NDA paperwork also stops me so much from making videos showing all the battery design and build I make. Some reeeeeeeally cool ones but sadly can’t share anything =/
Micah can you recommend a battery from Alibaba I have a Chinese my1018 chain drive motor it is 24 v 450 watt would like to use a 36 v battery should I change to the 36v controller as well hope you can help I am waiting for your 2nd part in the cheap conversion series I have used the disc brake back wheel and a good quality 24 tooth sprocket
why do retail ebike battries not seem to go higher than 52v. what are the pros and cons of higher voltage batteries ? since you live in Boston have you considered building an allwheel drive fat tire snow bike ? fat tire, hand crank, tadpole design ebike for paraplegic ?
Does anyone know of an 18650 1000w 48v battery that would be good for a 1000w hub motor conversion kit? I'm new to the whole ebike thing but I want to build one! Also I need a good 15 miles of range. Plz someone reply because I need help!😰😭
Restoring a Vintage 1961 Lambretta, Italian made scooter, because of size constraints i have to make make two batteries and connect them in parallel. ie, 20sx26p which will be TWO 20s by 13p batteries. My question is what size BMS do i get? because these two batteries will be permanently connected giving me 72v but each battery pack is only 36v, do i need a beefier BMS? Jimmie
Hi, could you recomend a motor controller which is fully programmable, has a power of at least 500W continuous and a DC/DC boost converter integrated. Link to website or manufacture Thank you. Please text me in case you answer my question
Love your Vids Micah. I present to you an enigma that has me perplexed. I am going electric for the first time. So I'm planning on going with a 500 watt rear geared Bafang motor, kit comes with a 22 amp controller. can I use a 48 volt battery with a thousand watts?
BMSs...I'm looking at a programmable one. $42 for a 7S. Expensive, but after watching a TON of videos I want to set charging to 4.1v. Extending the battery life, more charges etc., and safer. Also setting the discharge a little higher, probably 3.1v. Your opinion sir?
Hi Mike, I recently purchased a dual motor e scooter from Alibaba. Each hub motor has 2800 watts of power totaling out to 5600 watts. It also includes a 60V 35ah battery. When riding it consistently for 30 minutes the working moter heats up to the point it can't be touched for more then a second. Can this be a problem or ist just normal and its ok to continue riding it like this?
I enjoy your you tube video reviews. I am 63 and I’m interested in getting a EBike to use on streets and mostly on dirt roads for joy riding and scouting for hunting seasons. I live in PA and I saw that we have a 20mph rule for ebikes. Folding ebikes seem interesting (portable), comfortable seat is a must, I’d prefer to use the motor than pedal and I have a budget in mind of say 500to800 dollars (not sure if that’s realistic). Any suggestions? No local bike shops near me even sell ebikes so I guess I’d have to buy Online. Thanks.
Hi Micah I have ebike model MATE X-750W. My battery fail-48V/14Ah size 2x4x14 inch. Voltage output 42V battery terminal-when turn key to ignition position -drop to 0V. What can i do?
Thank you for all of the extremely useful information about e-vehicles, I own a 1979 Schwinn Stingray that I would love to use for short rides once in a while, but I live in San Francisco and the hills are impossible for my little bike. Do you or anyone have any advice on what components to use on the coolest bike ever? Any help is greatly appreciated.
I bought an Ebike two months ago. I'm interested in getting a second battery for it. I would like an exact fit, that is when battery is depleted, just be able to remove and put charged battery in. Is it possible to get and exact fit for the bike? If yes, then what information do I (or you) need to get an exact match? Thank you.
i'm starting a fat tired tadpole trike build .... what are your thoughts on using lets say 1500watt hub motors on the front wheels , or even 1500 watt motors on all 3 wheels ? i'm wondering if pulling to one side , or torque steer might be a issue
@NANO BOT that isn't a tadpole , it is a delta style .... and it is a single hub motor in the front tire, tadpole has 2 front wheels , that need to be sync'd or equalised some how with 2 hub motors .... points for effort , but not relevant really.
I can tell you that the first version at least will not do 1000 watts, it will give you 500 if you’re lucky. I think the second version performs a lot better.
Hi, love the channel. I have a question about ebike wheel conversion kits. I bought a generic 36v 20” ebike wheel kit from eBay. It included everything (speed controller, throttle, brakes) except the pedal assist sensor. I wanted to know if I bought a generic pedal assist sensor on eBay, would it work with the speed controller?
You’re my go to bike guy and when first getting into eBikes recently I consider your books a “must have”. I have a question referring to my car. I drive a Prius and the battery is failing. Would it be feasible to convert the original nicads to lithium flavored cells and matching voltages per cell?
If powering a 750W bafang rear hub motor, how much of a difference will 48v at 16ah make over 48v at 14ah? Also how can you calculate that cost to just go up by 2ah? Thanks.
I `m looking at converting my old fold-up mountain bike into a 250 watt front wheel drive Ebike - whats my best option for a camper van solar panel to charge the bike?
Hi. I'm from Brazil and have been very interested in EVs and their batteries in particular. I want to start a conversion EV's workshop in a near future to help to introduce the wonderful world of EV's to the people of my country. I couldn't help to notice that most if not all of their batteries are made assembling small battery cells in groups to achieve a desired tension and capacity. I understand that making and selling a bunch of 18650 cells are easier to the factories, and with the same cells you can achieve various tensions and capacities just by reordering the wiring system. But I was wondering, why doesn't exists, or at least is difficult to find a single cell battery that has, let's say, 48v and 13ah for ebikes. Wouldn't that be easier to charge, less prone to fail overtime because of the simpler construction and less number of parts? Sorry if my question is dumb.
waiting my answer but u not address. Come Nepal when u come india in visit Nepal 2020 . my question was: i want to use qs transmission motor with chain or belt drive in old dirt honda xl 185 cc bike to electric to get 60 to 70 km\h. What eill be the wattage of qs motor and battety capacity?
You can hook up 48v, no problems, just make sure your controller can handle 48v. Motors are not rated for volts, they are rated for watts or power, so just don’t exceed the power rating. There is no such thing as a 36v motor, sometimes it’s simpler to speak in those terms but in reality motors only have a power rating, so if you go from 36v to 48v you just have to lower the amps. A 1000 watt motor at 48 volts is about 21 amps, if I run it at 52v I just have to get a controller that is rated for less amps, say 19 and not 21. If you’re going from 36v to 48v and you have a 500 watt motor, you would have to go from a 36v 13 amp controller to a 48v 10 amp controller to decrease the amps for 48v. This channel has a video explaining these concepts.
lugbug27 1 second ago Hello great videos i have learnt so much from them, i have a question, i am making a battery pack with LG cells. the cells are LG INR18650-MJ1 3500mAh - 10A and i am building a 52v 14s5p configuration. This is my first time so i dont know much but i bought a BMS from vruzen rated at 52v 20amps. The motor and controller will be 48v 1000w. my question is the max current on the BMS is 20 amps (the 30amp one was sold out) will this be ok. I just checked that alot of controllers have a max discharge current of over 20 amps, will this affect the performance or effect the battery in any negative way? should i get a different BMS what would you recommend?
What is your take on the Copenhagen Wheel / Superpedestrian and any thoughts on the now out of business BionX ebike motor and battery’s, are they worth buying, I see some are still for sale. Really enjoy your videos, you have a 10+ presentation style and you are really knowledgeable on the subject, thanks
hey, i know the chances of you replying is slime but thought why not give it a shot. so im trying to build a dual 350w motor FATBIKE. i got your battery kit and built a new one. and have a second controller, but my problem is i havent been able to find a small front motor. like the size of a bafang 310. can i use a motor classified as a "rear gear motor" in a front rim. i have been looking at other front motors, but scared they will not be wide enough for the rim and ill have problems. please get back to me or anyone with advise that can help.
I'm the least knowledgeable in the ebike field, but I'm a buyer (ebay), a real life shopper. Sellers on ebay will answer your every question! If they don't then they don't want to sell you something.
Have a question. I wont trust anyone else to answer. So if i have 2 electric motors both rated at 1 horsepower or 745 watts. At the same voltage and amprage will the power of both motors be identical. I know some motors are rated differnt power at differnt voltages. I am asking because i have 2 e motors rated at 250 watts at 24 volts. They are similar size & weight but feel differnt in terms of torque and definitely top speed is not the same. Help?$??!?!
I have a $200 hub drive kit from ebay and a $300 battery from bananza 48v 1000w it will do 25mph and I do not peddle ever . 3 years ride it 20 miles every day going great now only time spent on work stand was brake pads and tire problems . Will I buy another e.bike yes but hope I never have to ya ya I know nothing lasts forever but I can hope . But the way I see it I got my money's worth and no complaints.
My aliexpress battery has a 30A BMS, its a 48v 16.5 ah battery powering my 750w bafang mid drive, i run about 50km topspeed, first build on a mtb but what does "30A" mean? I didnt even know it had a bms, should i be happy it does?
Love your videos, very informative and well put together. Definitely need to make myself a 2x2 ebike as well. Anyway, really my only question, one that I keep asking myself, is why has everyone forgotten about scooter ebikes? Im not talking about those stupid razor scooters, but actual scooters. Those big, 2 person vespa style bikes. It seems these days, wherever you look, everyone just talks about modified bicycles as being ebikes and those silly childrens razor scooters as electric scooters. I have one of those big 2 person scooters, with the big trunk, large cargo under the seat, all the bells and whistles. Anyway, would love to know how we've all forgotten about those. Thank you for posting all these videos and please dont stop. :) Oh and Ive just upgraded my bike. Added an extra battery to boost it to 72v. New 1500w/50A controller, with the 750C display and a 1000w motor. Thanks again.
@@EbikeSchool Ill have to check out that Electrek site. That GenZe is a very cool looking bike. Quite different from what you normally see in this class of ebike. Thank you for the reply. :) Oh and if I may ask another question, one for another AMA. Are you originally from Israel or did you make Aliyah? If you did, how was your experience, and was it through Nefesh B'Nefesh by chance? Thanks again :)
Hey Mike.. Denzel Motors is one company you should check out ... (youvtube is Alex Guliyants .:. Plus they have a new gearbox motor ( 2 bolt Honda 50cc motor style) C110 !!!!!
Thank you Mikey,

As far as City Slicker jitter, I discovered a problem with the factory tires and will do a video on it soon. Basically they have flat spots from sitting and shipping stress that makes the bike bounce. If you watch your first ride video forward camera look at the bouncing but the front forks don't move, suspect tire flat spots. I'll install new tires to test but it won't be anytime soon.

Great video as usual. Keep up the good work.
I have a battery powered EGO lawn mower. If my battery is "rated" for a number of charge cycles, if the battery is not fully exhausted, will a half charge still count as a full charge in this number of predicted charge cycles? Am I shortening the life of my battery if I charge after mowing and not waiting for the BMS to stop the mower motor?
Thanks for your help.

Never mind I just saw ur video where u said to do pretty much exactly that. BUT. Should I get a charger that goes to 28.7v., or is 29.4 ok?
Did your service with the military include electrical that you used in you ebike builds or did you learn it all on you own?
No I started learning this before the army and continued after.
Great video. Really enjoy learning from you. Thanks from Northern Ireland

waiting my answer but u not address. Come Nepal when u come india in visit Nepal 2020 . my question was: i want to use qs transmission motor with chain or belt drive in old dirt honda xl 185 cc bike to electric to get 60 to 70 km\h. What eill be the wattage of qs motor and battety capacity?

Congratulations on hitting the 50k sub mark
Can batteries be charged and discharged at same time..? Then how regenerative braking system is working..!!!?
Yes they can
Thanks for answering all the questions. I do really learn from all this.
Bro first of all i am sorry for asking question late i want to know can i use 48v battery for 36v motor if it is posible than how i can do that
@NANO BOT thanks and also than what shall i do
You can hook up 48v, no problems, just make sure your controller can handle 48v. Motors are not rated for volts, they are rated for watts or power, so just don’t exceed the power rating. There is no such thing as a 36v motor, sometimes it’s simpler to speak in those terms but in reality motors only have a power rating, so if you go from 36v to 48v you just have to lower the amps. A 1000 watt motor at 48 volts is about 21 amps, if I run it at 52v I just have to get a controller that is rated for less amps, say 19 and not 21. If you’re going from 36v to 48v and you have a 500 watt motor, you would have to go from a 36v 13 amp controller to a 48v 10 amp controller to decrease the amps for 48v. This channel has a video explaining these concepts.
Thanks David I'm gonna do kinda same thing as outher guy but 48 volt 10 AH to 52 21 Ah or maybe 60 volt 21 Ah but wait till I get his book tomorrow.
Great videos. I'm learning alot.

Hello great videos i have learnt so much from them, i have a question, i am making a battery pack with LG cells. the cells are LG INR18650-MJ1 3500mAh - 10A and i am building a 52v 14s5p configuration. This is my first time so i dont know much but i bought a BMS from vruzen rated at 52v 20amps. The motor and controller will be 48v 1000w. my question is the max current on the BMS is 20 amps (the 30amp one was sold out) will this be ok. I just checked that alot of controllers have a max discharge current of over 20 amps, will this affect the performance or effect the battery in any negative way? should i get a different BMS what would you recommend?
What is your take on the Copenhagen Wheel / Superpedestrian and any thoughts on the now out of business BionX ebike motor and battery’s, are they worth buying, I see some are still for sale. Really enjoy your videos, you have a 10+ presentation style and you are really knowledgeable on the subject, thanks
hey, i know the chances of you replying is slime but thought why not give it a shot.
so im trying to build a dual 350w motor FATBIKE. i got your battery kit and built a new one. and have a second controller, but my problem is i havent been able to find a small front motor. like the size of a bafang 310. can i use a motor classified as a "rear gear motor" in a front rim. i have been looking at other front motors, but scared they will not be wide enough for the rim and ill have problems. please get back to me or anyone with advise that can help.
I'm the least knowledgeable in the ebike field, but I'm a buyer (ebay), a real life shopper. Sellers on ebay will answer your every question! If they don't then they don't want to sell you something.
Can I use 4P10S BMS to charge 5P10S battery?
Hii good video what you think on BBHD? What bater mid drive vs hub motor?
I am glad to see this video . Sir please suggest me a top speed hub motor kit and suitable battery for it.
Speed 100km
And range up to 150km distance
1000$ sir , in our currency it's 67000 rupees
Please tell, how much it costs me sir.
AMX conversion would be AWESOME. I had one but it was irreparable...
Have a question. I wont trust anyone else to answer. So if i have 2 electric motors both rated at 1 horsepower or 745 watts. At the same voltage and amprage will the power of both motors be identical. I know some motors are rated differnt power at differnt voltages. I am asking because i have 2 e motors rated at 250 watts at 24 volts. They are similar size & weight but feel differnt in terms of torque and definitely top speed is not the same. Help?$??!?!
I have a $200 hub drive kit from ebay and a $300 battery from bananza 48v 1000w it will do 25mph and I do not peddle ever . 3 years ride it 20 miles every day going great now only time spent on work stand was brake pads
and tire problems . Will I buy another e.bike yes but hope I never have to ya ya I know nothing lasts forever but I can hope . But the way I see it I got my money's worth and no complaints.
City slicker vs Super soco max review please!
My aliexpress battery has a 30A BMS, its a 48v 16.5 ah battery powering my 750w bafang mid drive, i run about 50km topspeed, first build on a mtb but what does "30A" mean? I didnt even know it had a bms, should i be happy it does?
Thanks for the info. I'm painting all my e-bikes blue!
As always, good information. Great links. Your contribution makes it even more interesating.
Another good video, keep it up 👍..
Wow, you're really multi talented !
I have messaged you through your VRUZEND website and never got an answer.
Love your videos, very informative and well put together. Definitely need to make myself a 2x2 ebike as well. Anyway, really my only question, one that I keep asking myself, is why has everyone forgotten about scooter ebikes? Im not talking about those stupid razor scooters, but actual scooters. Those big, 2 person vespa style bikes. It seems these days, wherever you look, everyone just talks about modified bicycles as being ebikes and those silly childrens razor scooters as electric scooters. I have one of those big 2 person scooters, with the big trunk, large cargo under the seat, all the bells and whistles. Anyway, would love to know how we've all forgotten about those. Thank you for posting all these videos and please dont stop. :) Oh and Ive just upgraded my bike. Added an extra battery to boost it to 72v. New 1500w/50A controller, with the 750C display and a 1000w motor. Thanks again.
I love those scooters. I post about them all the time on Electrek. I ride a GenZe 2.0 and the thing is AMAZING!
Sorry I tried to cram as many answers as I could. Hopefully yours next time!
@@EbikeSchool Ill have to check out that Electrek site. That GenZe is a very cool looking bike. Quite different from what you normally see in this class of ebike. Thank you for the reply. :)
Oh and if I may ask another question, one for another AMA. Are you originally from Israel or did you make Aliyah? If you did, how was your experience, and was it through Nefesh B'Nefesh by chance? Thanks again :)
Hey Mike.. Denzel Motors is one company you should check out ... (youvtube is Alex Guliyants .:. Plus they have a new gearbox motor ( 2 bolt Honda 50cc motor style) C110 !!!!!
Thanks so much for doing this video!! We all appreciate a personal look at 'who is micah?'
