10kW 72v Electric mini bike build

[Jacka98]

what are your battery and motor temps after snow plowing for a while? Do they stay low with the fresh powder hitting the enclosures?

Actually Im not sure. I didn't check motor or battery temps. But nothing didn't overheat. I'm sure that cold air+snow helps with cooling. And I think that the motor would have burned without cold air and snow

Cool videos! Watched some of your other videos in your channel. Is the battery pack in the 72V 10kW minibike soldered with copper strips? Reason I ask is that I have a heavy duty soldering iron but no battery spot welder. I know how to solder but no experience spot welding if I ever want to build a pack.

Thanks! Yes it is soldered. I used ladder type 0.2mm copper strip.

That's really too cold. I hate it that it will start freezing (-1 to -3 degrees daytime) here from tomorrow for a few days.
Enjoy your "winter sports" on the mini bike!
