I soldered them back together and they work fine. It is lots of fun as long as you don't use the full power continuously like I have been doing, I need to hook up the cycle analyst to limit the current and only 'uncork' it here and there. I will go and drain it at WOT for 1/2 hr, the CA reading a draw in excess of 80A for extended periods, riding like a motorcycle without pedaling much, that is when it gets too hot and fails. I may just go back to the idiot proof 40A 56V setup and not have to worry about it, but the extra power would be missed.
