Re: 18-19 inch rim vancouver

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.

Re: Spot Welding Copper Strips to 18650 Battery Cells

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...

Re: Spot Welding Copper Strips to 18650 Battery Cells

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...

Re: Spot Welding Copper Strips to 18650 Battery Cells

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...

Re: Spot Welding Copper Strips to 18650 Battery Cells

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...

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...

Re: EM3EV battery doesn't discharge?

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...

Re: Another Stealth bomber (clone) build

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...
