Not with the motorcycle wheel. Lasted about 1 ...

Long nickel strips

Im looking for as long nickel strips as possible. Do you know some proven one (links?)?

For example instead of 0,15mm x 8mm better 0,15mm x 30mm.

Thanks

Re: What would you do with 5000€?

I think about building anything that is electric and selling it for a higher price again. Just missing realistic ideas. Thought about some water-projects but that eats up to much battery in too short time.

Re: Searching low € / kWh battery chemistry

I don´t care about how big it is. Its more important to last about 300 cycles and have as much capacity as possible. Budget is 2000€. Will be built into a boat.

If you need more regen then you need the more powerful Controller. That would be bad as the VESC from esk8.de (http://www.hellray.de/shop/#!/Electronics-&-ESC-made-in-Germany/c/15255004/offset=0&sort=normal) was made for 3kW also afaIk and still has a waaaaay better regen brake.

Re: Kelly KLS-S: Troubleshooting

I can continue right after it cuts out. The throttle for sure won´t be a problem as it only cuts off the accelleration when I accellerate too hard . The battery is a Samsung 30q 12s5p battery. Also the regen is still very week. Vehicle https://i.imgur.com/L434uLg.png Control https://i.imgur.com/R8xt...
