It's fun seeing someone regurgitate their battery build. I've done it a couple times now for people asking about builds. I'm glad I'm not the only one who gets into the weeds.
@@davisbradford7438 yes, the second that I get into even the basis everyone's eyes glaze over and I'm always surprised. I love this stuff. My first battery pack ever was a 4kw 72v pack. My advice to anyone is start out a little smaller don't do the inja pack as your first one even my 72v pushed me to my limits
I learned so much about building battery pack with this video. I think resistance calculations about wires that connects batteries into series and parallels are one of most neglected topic among battery builders. And here the pack builder talks more about it more than any other battery packs builder that I watched. Kudos to him for being so passionate and doing a great job.
I learned a bunch from the battery discussion here. I made my first 18650 battery for a Razor 72 volt dirt bike conversion and made a few mistakes that are explained here. I used low amp, high capacity Panasonic cells because I didn't know better and at 4 in parallel, have a huge amount of voltage sag when I ride the bike. I thought just due to the cells, but maybe also due to my wiring. I have some high amp output cells on the way and will do 10 parallel this time, but also focus more on the battery connections this time too.
Stoked for you guys. Love these long detailed videos. You’re going to love that hub motor combined with the available amps in this setup. Glad you won’t have to deal with the same battery issues on the cb. Those HUB motors are crazy powerful and wicked silent. Great design and execution on the battery Lord Curt! The fiberglass bottom was a nice touch. And the sense wires was nice and clean too. Will you run the entire pack through a shunt for monitoring? I like the idea of bypassing a smaller BMS for discharge. I’m still struggling with the space for a 2 phase charger on the bike itself so I can take advantage of charging stations. That would be so clutch
If they are running 32 in series (x 3.2v) wouldn't that be 102.4v? I'm guessing they are running 96v on the controller, and if so is going over voltage safe?
You just keep learning and making better and better electric bikes 👌 Lord Curt has put a lot of thought into building the best packs he can with the parts you get.
Battery looks good, but you forgot the cell level fuses. I would be very nervous about a pack this size without tesla style cell level fuses. You have a lot of faith in those Chinese cells!
thank you for sharing a parts list! been wanting to do something similar for years just always worried I would buy something that burnt up after a few hours of use. now I can see how it holds up
I really enjoy this channel, you guys are really awesome! You too compliment each other very well, I think this channel will succeed because the two of you are in this together. You guys are like the goon squad of electric vehicles lol. It's a good combination keep up the work guys!
I've been watching your videos from the beginning and I'm going through some tough times in my life right now you are videos really help cheer me up thank you👍👍😁⚡⚡
keeping in mind that there are several types of bms - single cell configs in parallel allow you to better take care of the cells but most of what i've seen about 10% longer lifespan - this also means more than one bms and a discharge controller (i've only seen them as hybrids with integrated multi-bms from oem or custom by a rare few) - on another note (and as with anything) i was reading about a lab study on lithium (i'm a pro batt and charger tech) before we start seeing it more on the industrial side and they found that LiFePO (i believe) cells are best stored in a dead state and that if they're stored in a charged state that is causes rapid degradation - waiting on the peer review to be sure but it's opposite for most all other batt chems - i'm my experience i would keep it at around half charge during storage and just top it off when you want to ride - lithium prefers opportunity charging so no memory effects
Yes lads ,love it,I am extremely excited,Lord Kurt is soon to be king Kurt,this is going to be the best build yet ,should make a ducat street cart with the engine 😃
Is some battery criticism welcome? Those cells need to be laser welded and NOT soldered because the heat damages the cells. This is even listed clearly on the sellers ad. Such a large battery pack divided into 3 parts- if and when you get a bad cell it is going to be a nitemare to fix. If you are planning to use the bike for the 5-7 year+ lifespan of the cells, the battery could be more modular. I am using these same cells for an ebicycle build and they are the perfect size. The cells I received had a piece of laser welded nickel strip on them already (cannot use a cheap spot welder on copper), so I can use a cheap $20 BIFRC spot welder to assemble the pack with more nickel. If I need to solder on some extra copper then it is a bit safer because I do not need to solder directly to the copper terminals. Amazing build overall, that is a HUGE battery. I learned some good tips from your vid, thanks!
2022 - Lord Curt (The Inja Garage) 5 Years Later... 2027 - Lord Curt (CEO Of Tesla) Reminiscing how he used to build battery Powered Motorcycles his friends garage.
I build my own liion battery packs for my electric skateboard! Lord Curt's knowledge of batteries is very impressive. Curious to know what his background/work experience is?
No formal education in this field. He learned it all from Google searching and reading/watching videos as we started our first battery upgrade a few years ago!
You really need to start top balancing. Put every single cell in parallel and then charge discharge a few cycles to exercise the cells. It doesn't matter for a YT video but anyone copying you is going to be very disappointed in battery performance. Great though process into the buss bars!
the ONLY thing im going to point out is that i wish it was possible to make the battery more aerodynamic and not look like a box attached to the frame but feel and look like its part of the bike itself, if you could solve that, it would be the perfect bike
So Were talking about a 12+ kwh lithium iron phoshate battery that weighs 160 pounds! Can not fit it in any smaller of a space, what a shame. I need this on my reinforced, moded MC wheel cargo side loader bike!...yet that is much heavier than the previous 7kw lithium ion battery, 100+ pounds. Need that solid bms setup for reliability this time. If it could maintains 30wh or less per mile then 300 to 320 miles on a discharge down to 20% battery left...exactly what i seek! Future plans while rubbing hands together. Very heavy indeed!
You could build basically the same battery pack with samsung sdi 94 ah batteries and it would be cheaper and easier to make. As a bonus it would be way more compact.
I'm loving THIS! YOU GUYS are inspiring me to build an ELECTRIC powered MONKEYBIKE! I'VE BEEN TORN - BETWEEN: BUYING A Honda Msx125/GROM OR Building my own "MonkeyBike-like" electric minibike! Ideally the minibike should have MonkeyBike traits like same dimensions as a MonkeyBike a range of 140-210 miles without being TOO HEAVY! I AM INSPIRED AND CURRENTLY AMPED!
That was a lot of really good information. These batteries are my choice for my solar set up. You welded yours? What would it take for a good contact conductor? Would be nice if I could have a giant rack that I could just drop in or pull cells as needed.
Wow that's the last thing l need to complete my bike I've thinking about building a battery if l could build one half the size of that my bike would fly 🤣
@@LordCurt Nice! That's what I got on my bike too right now. Let me know if you guys want to race 🤣 Btw you are very smart my guy! You helped me understand lipo batteries better than anyone. Building Lipos is very dangerous and you make it look easy. I appreciate you! Keep up the awesome work.
@@molifehacks5258 great to hear, man. Glad we could help. Is it the same setup you showed in your videos of the bike? If so, what controller are you using with it? It’s a solid system
@@LordCurt no, it's not the same setup, your battery is way more powerful in voltage. My battery is 88.2v 80ah with 600a peak discharge current. I'm running a 72v 600a peak controller. How many amps is your controller?
@@molifehacks5258 very nice, man! What’s the controller make and model? Our controller is a 800 phase amp controller, but that’s about 400 from the battery at peak based on what the manufacturer states. I’ll check it with a shunt and it’ll be in a video
I have an Electric Bike like your white China bike (mine is a Daymak EM2) and the 2 charger wires pulled loose and touched together, i replaced the charger port, now i can not charge and have no turn signals or headlights. The bike still runs and the dash lights up but will not charge... anyone know what could fix this problem? Dealer said i need to replace the entire wiring harness, i feel like that would be a pain to change out.

I’m still struggling with the space for a 2 phase charger on the bike itself so I can take advantage of charging stations. That would be so clutch
It’ll have a gauge for the shunt included on the tank for monitoring!
The difficulty of public charging adapters is way more than it should be. I’ll be looking forward to seeing you get that working!
There is no such thing as too detailed a battery build discussion. Love it.
That thing is going to be a torque monster when it's finished! Harley only wishes it could build something to this point of excellence!😁👍
Watched this four times now. Took me a bit to figure the configuration. Very clever layout of the 8P x 32S configuration. Well done
If they are running 32 in series (x 3.2v) wouldn't that be 102.4v?
I'm guessing they are running 96v on the controller, and if so is going over voltage safe?
This will be a good one , 100 volts can't wait to see what it does. Lord Curt the man supplying the power!
Can't wait to see the build continue! This episode reminds me that I have to sit down and make my new power wheels battery. Going from 1800W to 5000W
The Ducati is such a gorgeous bike, looking forward for the next videos, Inja, and happy new year.
Thanks for joining us on another journey! 💯
I’m a watch this on my lunch. I need to stop by and hang with you guys when you do this stuff. I wanna learn !
lol these batteries configurations are getting crazier ... and it LIKE IT... MORE POWER!!!!!!!💪
You just keep learning and making better and better electric bikes 👌 Lord Curt has put a lot of thought into building the best packs he can with the parts you get.
Lord Curt is a mixture of Awesomeniss and Badassery.
Keep on living your dreams.

That was one Very Merry Christmas at the Lords house lol
Is there a reason why you went 102v nominal when the motor will support more? I'm thinking about top speed. Awesome build!
Good job Team Inja 👏👏👏
Talented Guys 🙂👍
More like "Battery Lord" Curt! Geez, that thing is a monster it looks like it's almost as heavy as the bike before you removed the engine.
Nice build guys! beautifully constructed battery

Could server rack LiFePo batteries work for this build?

Watch those cable temps. I'm not sure 8 gage is heavy enough. That's a lot of amps going through a relatively small wire.
4 of them at each point! 2 gauge equivalent
@@LordCurt don't know how I missed that lol good eye sr. I stand corrected
is it possible for you guys to make an electric quad bike project too this build is awesome
Did I get that right, its a 13.2 kWh battery pack?

If SHE didn't also laugh you might have a talk with her later, cuz that was hilarious
Grt battery details bro. Superb.
Great work guys
Wish we had cells with double the capacity. Not even so much for the range aspect, but for the weight savings.
I can't see how to watch them in order, each time I click on a different link it says "previously"...Which is the first one?
