Hey man I finally got everything installed and had my first real ride session and it was a total blast! I was with a friend that had the same setup (literally put together in 4 hours day of) and we were sending it like crazy at a regional park. We were using 48v 14ah lithium batteries (could be the same exact one you have) and everything worked fine. We also really liked having regen and set it really high: braking was incredible. I hit a top speed of 35mph (could've went faster but there was a turn in the road) with field weakening set pretty low. (I weigh about 108 so I go extra fast). But yeah sorry for the long message but I just wanted to say thank you for your effort towards the build guide and inspo videos! I will try to upload my go pro footage to youtube asap. Let me know if you need anything!
@@JMilky7 that is super awesome to hear! I'm not sure which mount you went with, but I let my chain get too loose (from stretching I think) and didn't take care of it in time and the sprocket teeth got worn down. So keep an eye on that. Also instead of making the mount twice as thick, for the time being I used a bolt the length of the entire front and sandwiched some washers together with two nuts so they press up against the front of the mount to keep it from flexing. I still can't bring myself to spend 60 bucks on amount without trying my damndest to make it on my own first.
I am really happy to finally have gotten this thing together. I ran into some problems but took a breather, researched things I did not understand, and managed to fix them. There was extra noise coming from my chain not being lined up quite right as well as the Allen key for the sprocket getting stripped out. Then everything was acting strange due to the battery I was using being nearly dead. I was extremely frustrated! My current important settings in this video: Max amps from battery 30 Max amps to motor 100 Max watts 2200 Field weakening 60 amps Field weakening at 93% duty cycle If you don't know what field weakening is, check the parts list for links to some articles. If I had not understood what it does and why, my settings would probably not have been what they are. Good luck to all of you! P.S. I'm laughing at how obvious some these other channels are with their bought views and subs. It's pathetic behavior.
I’m so happy to come back and see this video! You have me absolutely stoked to try mine out! My motor and controller came in today and I’m gonna hopefully have mine ready to ride by next weekend. Look forward to more awesome tips and upgrades!
I really do not like the episode type of short release, even though that what I've done. I really want to make a master video with chapters. a real, thought out, scripted, one-stop-shop covering every last bit of knowledge and tips about modding. Due to that, I don't know that I will release anything until then, but you are welcome to ask questions. I might add a build guide to the parts page to tide people over until I make the video. With it being winter and cold as balls, plus me wanting to sell my red cart this week, I need to take as much footage and b-Roll with it that I might need before it's gone. I think the template will be that best ingredient I can provide for people who will not be buying it from chargedup3d. I will try to get that uploaded to the parts list tomorrow.
@@TheCrazyCartModChannel That would be tremendous, but I don't mind going back and watching the progress as well. Very cool that new motor doesn't require grinding the forks! I don't hear much drive terrain noise either, its "smoother" sounding.
@pcdoodle1 the red cart is even quieter. But yeah it's not too bad. Honestly I think the chassis of the red cart sounds quieter too. I need to investigate further.
You saund very happy I'm pleased you got what your were asking for Man. My 48v battery is taking months to arrive I hope I don't have to swap for the type of batteries your using.
@@albaniansuperiorshqipetari8055 well I'm taking those out for a second ride now that they're fully charged and we'll see what happens. I'm so relieved it wasn't a waste!
@@TheCrazyCartModChannelI'm happy that I was wrong about that motor you managed to get it tunned, what was your top speed on a 500w XL motor? That's the 500w xl motor I'm waiting to receive along with 48v lithium I will add another 22v 6s rc car battery.
@@MadebyMase by the way if you're looking at the real-time data you'll get a different speed than scrolling down where there's all this other data on a gray screen. It always said I went two or three miles an hour faster on that. I think the max it said was like 43 or 44 miles an hour
Hi there great videos! Quick question! I was wondering if I were to use my stock motor and 48v 1000w Brushed Motor controller with the 4 lifep04 batteries? Would this be workable and optimal? Also what type of charger would I need for this type of build?
YES! I appreciate your VESC video man. I ended up doing more research and diving into the desktop app as well. My idea after understanding field weakening was to only use it at the top end of the duty cycle so the motors normal torque could take it farther. Also after riding it with the 55t sprocket I felt like it had the torque to still pull alright on the 47t.
brooo how’s the low end? you think i could pull off this setup with a scud battery on my XL? maybe with different gearing? im trying to find a motor replacement atm to destroy this fat tire and thinking of going DIY route as usual lol
@@vicstfu9133 well the low end currently beats the pants off of my 500 w XL motor that's getting me 32 mi an hour so that's saying something. The cool thing about this is it's tunable. You just have to factor in the added weight. They sell a larger motor for about the same price that would probably dissipate heat better.
@@vicstfu9133 7070 means 70mm x 70mm. So the naming is the size. the KV rating is related to rpm/torque. I don't remember exactly how it goes, but it's something like higher KV equals more torque and less RPM, or it could be the reverse if that but I'm sure you'll figure it out if you research it.
@@Sly107_ not sure if you've looked at the build guide or not, but there's a link on the parts list. The I just use loctite on the tiny Allen keys and on the shaft. Don't ride until that stuff is cured. I'll add a link to the extra chain I bought awhile back. It comes with a couple master links as well I think.
I think you should try doing the top speed with a different app bc according to one guy it is innacurate... "Top speed of 54 km per hour with 40 volts of field weakening at 50 continuous amps. Whatever speeds these guys have been showing you, There not correct, In fact they are way off, by a lot more than I thought. When I was riding this, it said I was doing 80 km per hour through the app, but on my phone which is correct and has been tested to my car speedo. I was doing 54 km per hour. Massive difference. "
@@bubbachuck1 it literally measures motor speed, and if you have the math right about your gear ratios and tire size it is accurate. I confirmed it with GPS on my phone as well. When you scroll down that's when it gets to a part that is slightly inaccurate and I don't understand that, but at least there is an accurate part on the real time data like in my video.
@@Boemel Thank you for the input. It seems that this tiny motor might actually run into heat issues pretty quickly with these high amp draws. While you are making a great point, my channel is more geared towards readily accessible and relatively cheaper options than others are providing. I just wanted to make videos I hadn't really seen others make when I got into this. The batteries are being limited to 30 amps and the motor is getting phase amps. Not quite sure how it works just yet but that's what I've seen explained.
@@chazdoodle120 I actually wasn't even aware that that was a thing on crazy carts. At the very most, the next thing was going to be a brushless Hub motor. But I'm not sure. Do you have anywhere you can point me so I can look into this? Or is this just a concept you thought of?
@@chazdoodle120 I have not looked into it, but there's a reason it never caught on in the automotive world. They are complex, expensive and a pain to deal with I'd bet. The main reason you'd want something like that is so you could have a lot of torque at low speeds, and still have high speeds. The idea I was thinking that there may be a way to adapt a bicycle gear on there for at least 2 speeds or something. that would be really cool.
I have purchased a 48v 14ah lithium battery which likely has a BMS limit of 30A. How could I make the most out of this battery, or even bypass its limits, by tuning in the app or modification?
@@JMilky7 I don't know that you would need to bypass it, and I wouldn't really know how other than taking it apart and desoldering that, but unless you are proficient and willing to take the risk, I definitely would not do that. I think people are grossly misunderstanding that battery in this video. When I said the controller was asking way too much of the battery, that was because the voltage on the battery was already too low. It was at like 42 volts... If the battery is fully charged it should run the carton no problem, I just switched over to my lithium iron phosphate to make the video
I responded to this on my phone... I guess it didn't work for some reason. You can buy wire, but I just cut up an old power cable and crimped connectors on for the lifepo4 batteries. You can solder them if you want also. the lithium battery in the parts list comes with a charger and xt60 connectors already if you want to go that route.
Also, the harness in this video was fabricated by me, but I have since found a much simpler solution using nylon straps with bolts through them. you use the bolts in the frame through a hole you make in the straps. it's really secure, easy to remove and pretty cheap.
