I have a 26" Q100 rear motor (the 36V 20-ish mph version), still new and in the box that has been sitting in the corner of my room for like 2 years now waiting to finally see the light of day. It comes with everything you need except battery and controller (comes with throttle, display, hall se...

No spotwelding DIY battery kits - 36V 20AH & 48V 20AH

Hi guys, You might remember a kickstarter I ran a couple months ago for my battery building kits. I have a small production ready ready. I went with only the 36V and 48V 20AH kits for starters, as those were the most popular ones by far. I also dropped the kit prices to $369 and $469 for the 36V and...

Re: No One Gives A Rat’s Ass

I think it would be ultra cool to have a 10A or 15A discharge can in the 4.5 or 5Ah range, That sounds like a 26650 cell to me. Or Tesla/Panasonic's new 2170 cell. I'm not sure what the final AH rating on it is, but it's right around that level. Not sure about the discharge rate, but 2C would give ...

Hi, shipping to Canada would be $86 for 20 units. I know that's kind of high, but that's what my shipper quoted me :(
Weight seems to be factored into the cost less as weight increases. Twice the number of modules only adds like $20 to the shipping...

That equals extra long range. and an extra long board :lol: Do they make long board limo's? I believe Tesla is using these cells (NCR18650b) up through the model S line, and is now switching over to their new cells they've codesigned with panasonic in the new 21700 size. From what I can tell, it's ...

1s6p Panasonic NCR18650B 20.4AH modules $23

You guys might remember my Kickstarter for a battery building kit from about 6 weeks ago. When I thought I had a good idea, and because 18650B cells were becoming harder to source, I invested in a pile of professionally welded modules. Then my Kickstarter didn't succeed and now I'm sitting on a pile...
