Is anybody going? As of this posting, its only 13 days away There are three cities, New York, Chicago, and Las Vegas one which is called "CABDA West" The event is at the World Market Center I don't even know if there is any ebike stuff there, but there is still no Interbike this year

I've heard this before, it must be an engineering development term.

Here's some useful info, with pics... https://www.electricbike.com/mid-drive-kit-igh/

Ford Lightning Truck, Ford Mustang Mach-E Another teardown video from Munro Live on youtube. In this pic they are showing the difference between the Ford Lightning truck cell and the Ford Mustang Mach-E cell. They are both the same thickness, but the truck cell is slightly taller and wider...

Porsche and VW, they seemed to have collaborated on several design features of the modules. VW uses a roughly 400V architecture, and Porsche uses 800V. The modules look identical, except the VW cells are twice as long, with the end-caps being identical. For configuring a DIY pack for a...

Everything I've read indicates that adding an even pressure to the sides of pouch cells is a benefit. I have seen tech data on using as much as 100-PSI, though others wrote that they used as low as 20-PSI.

Can't believe I didn't think about this sooner. Use a direct drive ebike hubmotor as a 48V generator. Here's a 4-minute video of that

When a standard 220V generator is used, what is the best way to convert it to DC? What would the resulting DC voltage be?

There will be more to come, but this is a starter... https://www.electricbike.com/12-electric-vtols-that-are-actually-flying/

Thank you all for the thoughtful answers, you gave me some interesting leads to research.

The Zero battery pack is 28S, so when fully charged to 4.2V its 117V, at an LVC of 3.0V its 84V, and nominal 3.7V is 103V Two of them in series (or four 14S packs) would be 206V nominal...234V fully charged. I'm wondering if I can use a common 220V generator set to keep the vehicle running...

Look at the copper nickel sandwich method before you get too deep into this. It may be helpful to you. https://endless-sphere.com/sphere/threads/copper-nickel-sandwich-buses-for-series-connections.108006/

Take lots of pictures of every step. This is very well done, ad it will be helpful to others!

Are you able to take more pictures of the details?

I recall reading about how youtuber "Rich Rebuilds" took the 102V drivetrain from a wrecked Zero motorcycle, and adapted it to a light vintage hot rod with a 3-speed manual transmission. He ended up using only two of the gears, but he reported that acceleration was very nice (and certainly...
