with the batteries.
Note
For Battery 1 and the last battery of String A, you must
install additional tab washers to connect the Battery
Management System unit power wires (String A wires 34
and 35). For each unit on the system, attach one
additional tab washer. For example, a four-unit system
would require five tab washers stacked on top of each
other and offset on the positive terminal of both Battery 1
and the last battery of String A. This would include one
tab washer to manage the battery and four tab washers to
connect each unit’s power wire.
