Re: Vector Light Frame - Any others I should consider?

Thank you for the response! This was helpful. Weirdly I don't see the option on Vector's website to buy a battery with the frame. That sure would make things easier though. Do you know if this is an option that I'm just not seeing on their site? Assuming I went with the above recommendation for the...

Re: Vector Light Frame - Any others I should consider?

It really depends on how much money and effort you're willing to spend. For the motor, a solid choice would be the MXUS 3K turbo v3. it's a little overkill but a great motor that doesn't cost much more than the mid-range power motors, order one laced onto a wheel to speed up the build process, it mi...

Re: Vector Light Frame - Any others I should consider?

Vector light sounds pretty perfect for your requirements. Next is figuring out how much power you need to reach your required top speed, for 45mph that'll be around 4000w peak. After that it's matching the motor kv with wheel size, and your battery voltage. You'll find yourself needing maybe two typ...

Re: 22s12p battery, 320A max. How do I design the copper and nickel strips?

It's currently very difficult to spotweld copper directly onto the cells, and instead of stacking strips, you should use wide nickel strips for overall bigger cross section, which has much more ampacity than the usual grid-shaped nickel belt, that's what I do. If you want copper, consider doing what...

This starts off a bit confusing to me. Are you building a bicycle or a motorcycle?

Motorcycle, think vector vortex or kuberg freerider, something like that.

Re: Design help?

You could spot weld nickel for the parallel connection and then solder on copper for the series connection. However, you need proper soldering experience and a very strong soldering iron to not bring too much heat for the cells, or else you will damage them. This person did it with great execution, ...

Re: Design help?

Instead of getting the grid-shaped nickel like the one you posted, consider buying just a wide nickel strip , that way you have a much much bigger cross-section. 0.2mm nickel will probably work but since you have a Kweld, which can handle 0.3mm, I'd go with the latter. As for the current dissipation...

Anti spark troubles

I built a bottle mount battery, and whenever I put it on the bike it sparks at the prongs of the base.
