    Please help me solder this hacky co-op battery

    Thanks everyone! I didn't pay for it yet, I volunteer at the co-op and wanted to take the opportunity to test it before I or someone else pays money for junk or gets hurt.

    Heinzmann 36v 750w controller & battery

    Hi everyone, have learned much from the forums from lurking, but it's time to seek some specific help. I got a Heinzmann 36v 750w 30A hub motor from the local bike coop. I plan on lacing it to a 20 inch rim and using a Crust Clydesdale type fork to upgrade my food delivery bike and hopefully...
