If your looking for moto rims this chinese company hooked me up when no one else would even bother. https://ncyclebike.aliexpress.com/store/2214086?spm=2114.12010615.pcShopHead_2523220.0 They already sell front lanced wheels for 20mm axle bike forks. If you ask nicely like I did, they will even sell...

All my welder does is shorts a 800CCA car battery for the amount of milliseconds it is set to. No control over the pulse current lol. Even though it has some issues, I think this is a good solution vs buying that $10,000 welder at the start of this thread. yes you do have control of the current! ju...

sounds like your max pulse current isnt high enough. if it takes 40ms to make the weld, i think thats too long and will probably dump too much heat into the weld. your looking for a massive burst of amps in like 7ms or something. i think you would need ballpark 2000A to attempt copper welding, with...

I finished building a 52v 13.6 ah battery with nickel(0.2mm) and copper(0.15mm) sandwich taps. It's kind of a pain in the rear. Keep in mind. I was using a Malectrics Arduino Battery Spot Welder with a 800CCA car battery. I had to set my welder to 40ms(normally I can weld 0.2mm nickel with 16ms) pul...

Looks like he is successfully spot-welding 0.20mm thick copper to 18650's. There is no split down the center. The odd thing is that he is making a sandwich (at 08:40) with copper touching the cell, and 0.20 nickel over top of it, then he applies the spot-weld. The first part of the video he demonst...

I ordered from here https://annpower.aliexpress.com/store/6 ... 12f7q56eiF
Lets hope this is pure.

I recieved this nickel strip and its pure.

I buy from these guys too and can recommend. Also they have it in pretty much whatever thickness you want.

I'm not sure how you did that lol. So you are probably going to want to cut the wires on both sides of the connectors. Then replace the connectors. :warn: Make sure after cutting each wire you put tape on it or cover the wire so you don't take the chance to cause a short :warn: You could also just c...

CSC introduces its first electric motorcycle, the City Slicker, at $1,995 That is a great price, depending on battery capacity and power. The City Slicker has two operating modes, Power mode features a top speed of around 45 mph and Eco mode maxes out around 35 mph but gets better range. According ...

I am setting up my QS205 with my Sabvaton 72150. I am using a 72v li-ion 18650 battery. Wondering if anyone has any experience and can offer advice before i start making all the connections and running the hall tests. Not really as it's pretty close to plug and play with the QS205. The only thing I...

Also, thank you all for the suggestions and perspectives! You guys totally rock!

No problem my dude. Just start ripping it up out there

I'm just metering it from the discharge points (with the pack disconnected from the base/holder thingy). So just from the prongs that would connect to the base. The motor I am running is a gen 1 magic pie. I know the controller is designed for 24, 36, and 48v inputs. As far a a the battery voltage ...

I'm pretty sure they are running that qs motor kit that includes this motor + swing arm on an electric motorcycle called the city slicker. https://i2.wp.com/canadamotoguide.com/wp-content/uploads/2018/07/CSC-City-Slicker.jpg?w=720 https://www.revzilla.com/common-tread/csc-introduces-its-first-electr...

If your picking up that voltage, I doubt its the battery. What setup are you running on your bike? I know it seems silly, but is there any chance you have a 48v bike? I only ask because a lot of 48v controllers tend to cut out power at or around 42v. (your lithium battery is full at 41.7v and 3 SLA'...

@SirLongAss That bike looks great! What kind of trips do you get up to on that? Also... I didn't realize the BBSHD had a torque sensor... I thought it was just cadence! I get like maybe 50-70km on that bike with a 72v 20ah battery(1440 wh). It's really crap for rolling resistance. I'm pretty sure I...

Hey All, So, I finally decided to build an ebike. I've never owned one, so I think some of my questions come from a fundamental lack of knowledge. That being said, I'm very excited to learn and have already read so much about everything! Anyway, I want to build a bike that is _mainly_ for long dist...

Ive got $3000 in this build. I tuned the controller down so it only does a max speed of around 45 mph..which is plenty for me....I weigh 230 lbs and am 6ft 5 inchs tall. I also toned down the phase amps, so it has adequate torque, but not so much as to overheat the motor. I mounted my controller un...

What exactly is good about Bafangs PAS system? I suppose it's more on par with ebikes that come with a mid drive from the factory. It makes you feel like you and the motor are 1:1. I think it's just software. It has a few features that are better implemented then you're run of the mill cadence sens...

Hi, I own two bafang's and zero cyclone's (althought I will probably buy one at one point). From what I've seen by researching the cyclone for a while is that people seem to always struggle getting the one side of the mounting braket bent to fit their bottom bracket. Same bracket for all (I think It...

Dude you nailed it. So the issue was the hall test. When I wired up the bike the motor spun fine so I never did the hall test. As a result I think the although the motor ran it ran very inefficiently causing lots of heat. One I ran the hall test I hit the throttle and the wheel spun backwards, so I...

Maybe you're wheel isn't true'd or perhaps the wheels need to be balanced. Both are very easy to check. My gf's bike is like yours. I can get it going 55km/h and still be fairly stable. Thanks for your comment. Gives me hope it is possible to improve stability! Could you please elaborate a bit abou...

@sirlongass, Shit, you're right, funny pic dude. I was going to rock it that way lol. I was going to use it for superman seat grabs (pic below). Flipped that sucker around and what do you know, fits slightly less shittier. Going to add some additional brackets and mounts to get the seat some more s...

Holy shiz... Yesterday I the guy added that he got to cut off while the controller's cut off is 40V! meaning that they settled at 2.6V but the sag to get to 40V means 1.9V Just worry about the idle voltage. I just noticed you said the cells had puffed. You're friend should depose of them. The puffi...
