Terminals and lugs for large cross-section cable: tinned copper tubular lugs for 95 and 120mm² cable, with M8, M10 and M12 eyes, the ones needed between battery, busbar and power inverter.
On a 120mm² conductor crimping cannot be improvised: it takes a hydraulic tool with the correct die, because an incomplete crimp creates contact resistance, and at 200A that resistance turns into heat at the terminal.
Check the eyelet diameter matches the stud on the terminal and allow for heat-shrink sleeving to insulate the joint.
