Biggest Electric Motorcycle Battery: FULL EXPLANATION! 60,000W Ducati Conversion

[@keithengle592]

Watching you build batteries makes me simultaneously think "I could do that!" and "no way am I ever doing that!"

[@michaelnichols1977]

This is looking great man. These behind the scene videos are Super inspiring and to see this project coming along and getting legs is very exciting. Keep up the good work!

[@LordCurt]

Thanks, man! More in the works this weekend, and I’ll try to get updates out at the same time as the Inja each time he posts

[@69Dartman]

I have a couple of the old Weller big gun soldering irons for big stuff, and a torch that can do propane or map gas for really big stuff like radiator tanks and copper plumbing pipes. I just got a really nice 80 watt soldering station with adjustable temp and all kinds of quick connect tips for electronics repair. Usually use a small 15 watt iron for really delicate fine work. Really cool to see somebody that really knows what they are doing and why, makes it look easy, great video as always.

[@LordCurt]

Thanks, my friend! Looking forward to seeing it alive in the bike

Great to have you over here as well! I’ll be posting up a lot more videos of the projects in the coming months

[@riveldale9968]

Hey! I just came across this video after I watched the build series, nice work there mate. If I may suggest, I think it would be much better if you mount your camera on top of what you're doing, it's like a birds eye view of your work.

[@AlenHR]

This is amazing. Thanks for showing the whole process. Is there any reason you used soldering over spot welding on cells?

@@LordCurt How is the difference of your max-min Volt? And how much capacity you think the pack has (let's say discharging from 90 to 10% ) at normal temp in miles?

[@LordCurt]

@@axelkovac391 the max voltage of each cell is 3.65, and the minimum is 2.5. On our pack, that goes from 116.8 peak to 80 minimum. However, 90% of that Is been between 3.4 and 3 (109v and 96v). There is like 11750Wh between those voltages

[@LordCurt]

Much appreciated, man! I’ll keep you all updated behind the scenes like I did here

[@GaiusGarage]

Amazing job, Curt! so much thoughtful and proficient work in this pack! Ive always been a bit reluctant to use alot of hot glue on a battery pack because it has a fairly low melting point and my feeling is that as the pack heats up during heavy use, it would cause the glue to soften or run. I guess if your battery pack is hot enough to melt the glue, you probably have bigger problems, but I kinda figured even a slow warming might be kind of an issue - would love to know your thoughts! Also, where'd you pick up those aluminum tubes for the swingarm? I'm looking for similar parts for a motor mount

[@LordCurt]

Fair concerns, but I don’t expect this pack or any well designed pack gets up to that point. It’s rated to melt at 100C. The metal all came from onlinemetals.com

[@GaiusGarage]

@@LordCurt yeah I guess its not a good sign if your pack is at 100C. thanks for the link! post more videos on your channel man! The Inja stuff is great but its awesome that your channel gets into the nitty gritty technical stuff

[@mateosoaresportela4529]

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

[@christianpaulroldan4010]

[@davidepedicillo5776]

can you explain the final specs of the battery (Amp Volts) and of the singular cell

[@erikjansen5693]

Hi curt. Amazing job man. Thank you so much. I learned alot from your how to video. I have a question regarding the discharge. Am i correct in understanding that because of the high amperage of the battery you dont use the discharge port on the bms? If so can you please clearify a little on that issue? If you dont discharge via the bms that would save a lot of money spending on a big bms. Will the charge function on the bms work well in this situation, is there a special config needed? Hope you can reply. Thanks from erik from the netherlands

[@david-gd2zj]

What’s the charge time?

[@roodick85]

Strangely enough…that whole setup looks like a twin to my Energica Eva lol

[@stephenmanton5511]

Great video going through the process of how to build a battery. I'm currently thinking about doing something similar using battery hookup 32650 LiFePo4 6ah batteries (24s10p). Could you do a video on how you charge your battery pack once built? Any thoughts on building your own charger to take wall outlet ac to dc at your battery voltage, maxing out a wall outlet amperage limit

[@YoodielandExplorer]

Did you end up doing this?

[@Hush0187]

Is there anywhere I can find a diagram of how the connections are laid out?

[@rgreerjr]

Heck yeah, I didn't realize you had started posting videos, quick and easy sub for me. I do have a question related to the charging of the bike yall are currently converting. Do yall have any plans of adding a charging module on the bike so that the rider would be able to use public charging stations/regular J1772 chargers or how are yall planning on tackling the charging of the bike? I have wanted to do my own conversion on some kind of bike but I would ideally want to be able to charge it at public charging stations and not have to worry about bringing my own external charger to plug into a wall socket.

[@LordCurt]

Glad to have you here as well! We’re not planning on adding onboard charging because of the cost and weight, but it is possible to do. You need to effectively have a computer onboard to communicate with the charging station, so that is where the difficulty comes in

[@rgreerjr]

I guess that makes sense, I have been doing most of my research by watching and reading up on Car EV Conversions because there isn't a lot of info on or people doing Motorcycle EV Conversions. I still think it would be very beneficial for you all to do the research and include a on vehicle charger/charge controller with J1772 plug and possibly updating/upgrading to better quality BMS boards so that you can more easily monitor cell voltage and have the ability to have/use CAN Bus communication for things such as dash/displays.

[@LordCurt]

@@rgreerjr definitely a good thought for future projects. As of now, these units have that functionality via Bluetooth connection to apps, but that requires checking in on a phone. Not easy to look at while riding, but you can monitor cel health, etc

[@axelkovac391]

@@LordCurt you can mount a 10 amp charger under the seat. With a simple 3 meter cable you can get at minimum 50 miles in 30 min.

[@LordCurt]

@@axelkovac391 a 10 amp charger would get you less than 10 miles in half an hour, unfortunately. You’d need at least a 50 amp for that amount

[@shimpianiket]

Why did you go with these smaller round cells of 15ah instead of the solid prismatic cell packs of 90ah?

[@LordCurt]

Two reasons. These have higher discharge capabilities, and they can be used to make more specific shapes. It allowed us to fit it in the bike much better

[@shimpianiket]

@@LordCurt Makes Sense. Thanks!

[@eastwood111]

Is the weight of the battery cells actually 268 grams? Did you have a chance to measure a cell to figure out the exact weight?

[@LordCurt]

They were almost all within 1 gram of that weight. The precision was a little surprising

[@ganeshkambalimath3580]

Sir how much did the whole battery cost

[@LordCurt]

About 1900 USD. Not cheap, but as cheap as it could be, realistically

[@eastwood111]

What’s the dimensions for one of those modules? So you have 8 cells wide and 15 cells long which would be very similar to what I’m building. Thinking of building 30S 6p with 2 modules that are 15S by 6P. I believe your pack is 32S by 8P but it would be nice to know the size of those modules to see what I can fit in my Rmz 250 frame. Thanks Curt!

[@LordCurt]

You’re right on with the 32s 8p, but I only had 6 wide on the layout. Each parallel group spanned over two rows. That does make each module 15 cells long, so they’re 15 x 6 in terms of overall layout.

[@eastwood111]

@@LordCurt Thanks for the reply! Do you happen to have the dimensions for one of those Modules that’s 15 x 6 cells? Where did you order your cell holders? Thanks a ton!

[@yashsolanki1894]

Can you just share...how to buy this all products..motor, controller, batteries

[@LordCurt]

Cells were bought from AliExpress, as were most of the electronics like charger, BMS, etc. The motor, controller, display, and throttle were all bought from QS motor directly. Just reach out via email with your needs and they’ll help put it together

[@roodick85]

Ok man I got a question….could you build me one of these for my Energica Eva. I don’t need an incredible amount of range but id like to have the same dimensions in the case but lighter if possible

[@LordCurt]

This pack can’t quite meet the output demands of an energica. It’s made more for distance than output since the motor on the Ducati is lower power than an energica. It’s only good for about 70 horsepower peak, while the energica needs 115 according to motor and controller specs. You’d need some higher output lower capacity cells

[@roodick85]

@@LordCurt I've been looking into the inverter it reads 100-300v rating. Does that mean the contactors close at 100v or would it have to be programmed to close at a lower rating than say 250-300?

[@DwarfSin]

Hi bro I have the same battery, but there is a problem that it cannot charge more than 3.3v. do you have any problem??? . They say that each cells discharges 75a, is that correct?? What do you think??

[@LordCurt]

In the bike I’ve been able to pull 60 amps out of each with no problems, but I do not have a controller that can pull more than that. I also have been able to get them up to 3.45v each and just stop the charging there. There’s no advantage to going higher, and it only degrades the cells. Overall, I’m impressed with the cells!
