ELECTRIC CAFE RACER For $4,000 - We Built the BIGGEST LiFePo4 Motorcycle Battery on Youtube

[@TheGarfield106]

Lord Curt is the best. He reminds me a lot of my high school electrical teacher but a lot easier to understand.

[@leondenhollander7171]

he is great

[@GaiusGarage]

Interesting solution bypassing the BMS on discharge - I guess as long as you manage your discharge current within the limits of the pack and make sure never to discharge below 2.5V per cell there's really no reason to pass discharge through BMS. On the other hand, its nice to be able to electronically manage over-discharge and low-voltage protection via the app, and ANT BMS makes a model capable of 450A discharge at a very reasonable cost. Good arguments to be made for BMS and bypass BMS

[@Blown75]

Thanks for putting it in understandable terms. Can't wait to see the next step, I will be watching.

[@TheRealAlpha2]

Super informative! I mean, I understood maybe 2/3rds of it, but I actually felt like I was learning a little about building batteries by the end, so thumbs up for Lord Curt.

[@TheInja]

So good 🙌🏽

[@69Dartman]

Missed the original notification for this but watching it now. He's doing a great job of explaining things as he goes even if everyone doesn't completely understand it. When you truly know how something works and should go together it's like breathing for you and just makes sense plus goes quick. Everyone else is like how'd you do that... 👍 I used to do a lot of electronics repairs and car stuff, plus I build my own computers and understand stuff like that. It always helps to have a friend who can take it to the next level.

[@RunningDigital]

Just discovered your channel. Nice documentation. Already decided on this battery type for a supermoto build. My finished battery pack serves 72v 40Ah. I didn’t go bigger because I prepared the build for on-board fast charging with Type-2 connector. We have so many commercial charging options here in Sweden that I could compromise the Ah for less weight. Now I’m researching super-capacitor benefits thanks to your build.

[@ВадимИльев-х1п]

Hi, how did you realized type 2 charging? Is it possible to 72v 120Ah battery? Thanks.

[@NemoEUC]

How has Zero not hired this guy by now

[@TheInja]

Right????

[@knightsljx]

because they know that's not how you build a battery pack. You need some sort of metal or solid bracket to clamp all the individual cells together, not just tape. The outer metal box doesn't count. the bus bars are bolted meaning they're not going to move. so if you just tape the cells together, they ARE going to move, however minuscule, especially on a bike. Because tape flexes. And what will happen is that the bus bars are going to start damaging the cells. If you look at any sort of lithium battery building kits, they always comes with some sort of bracket to stop the cells from moving, relative to each other.

[@SniperSnake50BMG]

@@knightsljx well for a homemade battery pack that one is really well done, there is plenty o tape so it's not that bad for the vibration and when you see it enclosed in the metal box it fits nicely that I don't see the flexing being a problem and at the same time sealed with silicon so for me it is pretty safe for the pack itself

[@shredmas]

@@knightsljx True with lithium iron phosphate lifepo4 they swell up during discharge & high amperage charging. So they need to be clamped to hold their shape. That metal box might help

[@user-zi5rs1by7b]

@@shredmas lithium "iron" is not a thing... lithium ION is. however, these packs are Lithium Ferrite Polymer. Very different chemistry to LiOn. You are very correct about the brackets and vibrations cracking the terminals tho. Which could end up bad.

[@donscott6431]

Will the fact that there is a connection between the bms circuit, which is separate from the balance-wire circuit, AND the balance-wire circuit, cause an “internal” discharge of the battery over time? Depending on resistance differentiation between the two circuits? May need diode

[@galactic_kiwi]

LiFePO4 probably wouldn't be my first choice for batteries in an application where weight and power density matters but out of curiosity I thought I'd compare it to the batteries I used in my last 18650 pack. Each LiFePO4 cell is 2100g which equates to 42 Samsung 30Q 18650 batteries. An equivalent size 30Q pack would provide up to 630A continuous discharge over 270A, 126 AH capacity over 90 AH and 12.5% higher voltage. The LiFePO4 pack would cost US1.5K and 30Q pack $4.8k. Well the LiFePO4 is definitely cheaper and better value I guess.

[@TheInja]

And waaaaaay easier to assemble. We built two battery packs from 18650s for our last electric build and it was so freaking time consuming.

[@galactic_kiwi]

@@TheInja Yeah I can imagine. Took long enough making my 84 cell pack, although I layered up the nickel strips for lower internal resistance.

Hi Inja love these vids, have another question for Lord Curt, regarding Regen if you start with a full battery and the first leg of your ride is downhill do you have to have a dummy load to “vent” the excess electricity?

[@JasonWW2000]

The battery voltage needs to be low enough to put a charge into. If not, regen will not work.

[@SniperSnake50BMG]

@@JasonWW2000 that's right if you are in full charge it simply won't Regen (or regen at too allow speed like 10mph), you would have to use you friction brakes

[@TheInja]

I'll add the link for you right now!

[@TheInja]

To the description

[@SniperSnake50BMG]

Thank you very much Inja. I have been looking for parts for the bike I have projected. Recently here in my country some importer have imported a R3 knockoff that seems pretty good to work with and since I have been using my first electric motorcycle with LTO I want to create a similar project like yours but with a bigass LTO 18650 pack similar to your white bike but with slightly bigger capacity; 120v system and around 90~110Ah, I'm wondering if the seller of the BMS have a more parallel for a 45p to sum 126v if is only 32 will only be 89v(more range but less per). Possible a Kelly of Sablotom controller and in deciding if a mid drive motor like yours or a 12kw v3 hub motor... What I am most focused is the battery pack. Is similar to your white one but I will be using all the space to the top probably end up cutting a little the frame to make fit the pack.

[@donscott6431]

That’s gonna be one hellish powerplant. 270 amp discharge capability... what does an electric chair in a prison have? Let’s get a percentage....

[@RetroElectric]

Awesome. how heavy is it?

[@LordCurt]

We’ll have to snag a weight next time! Should come in at right around 150 pounds

[@RetroElectric]

Lord Curt is that too heavy for a motorcycle? What a target goal for a motorcycle weight and kWh?

[@LordCurt]

Electric-ATV Channel I mean, the less weight the better, and the more KWH the better. This one is about 10kwh, which is actually pretty typical for a mainstream electric motorcycle. The Energica has about that capacity, but the weight is WAY higher. We’re still adding 6kwh more, and that’ll add another 80 pounds. It’ll have over 16kwh at point, weigh 230 pounds. The Harley livewire carries less and weighs 250 pounds. Plenty of bikes have heavier, but a smaller number have more capacity, so we’re on track. It should be close to the stock weight of the bike when we’re done.

[@RetroElectric]

@@LordCurt got ya!

Hey guys nice pack.. I would like to suggest not to pull accessories wire separately use a Dc to Dc 12v or what ever step-down voltage or amps you require from a 32s pack and for the discharge part do not use direct wires use the BMS yes I know your BMS doesn't support high amp discharge use a 300amp contractor for the BMS. It's for safety and life off your pack. All the best

[@Blitzoffroadliveindia]

And add a fuse rated to 25% more rated than discharge current. Or else you will smoke it up like the same clip in your videos which played now and than.

[@whitepaperkat67]

From my understanding that type of battery has a lower energy density than lithium ion, but it lasts longer I think

[@BigMan7o0]

Wrong, you'd need 3 of those packs for it to weigh as much as my mom 😎

[@TheInja]

Always a concern that you get faulty equipment. But it shouldn't be a problem!
