Connection diagram

Connection procedure:

1. Connect the batteries in series.
2. Connect:

• For split port mode: the negative terminal of the charger to the terminal C- and the negative terminal of the load to the terminal P-.
• For common port mode: charger negative terminal and load negative terminal to terminal C-.

Connect the positive terminal of the charger and load to the positive field of the batteries. Connect the positive pole of each battery to terminals B +, B4, and B3. Connect the negative battery field to the B- terminal (connected to B2 and B1).

Split port mode

Same port mode
