Hi Mark, Thanks for your interest and suggestion, I did a complete survey of Ali when I chose the connectors. For the Battery & Choke connectors I am going to use tinned red copper solderable lugs they are 1.5mm thick, the ones you suggested are 0.8mm tinned brass and they worried me a bit for higher currents, but I welcome suggestions like this !If at first you dont succeed, I suggest you avoid sky diving.... Cheers Mike
