Step 1: Connect the B- to the battery negative terminal (weld the stub first). Remove cables from BMS before connecting.
Step 2: Start wiring from B-. Connect the sideline B1 to the positive of the first battery, B2 to the second, and so on.
Step 3: Test voltage between adjacent lines. Li-ion should be < 4V, LFP should be < 3.5V. If correct, insert the line.
Step 4: Connect the negative terminal of charger/load to P-/C-. Use bold cables for high current paths.
