2.1.1 Powering with Batteries and Wiring Harness

There are two ways to power this CC2662RQ1-CSU-EVM, the first way is by using a battery module and wiring harness. When power the board with a battery module, the user will connect the wiring harness to the corresponding connectors on the bottom of the board.

The connector closest to the J5 standoff will be used to connect the uppermost cells, the middle connector will be used to connect the middle cells, and the connector closest to the J6 jumper, will be used to connect the bottommost cells.

In the wiring harness, there are two wires on the top of the module and two on the bottom of the module. One of the wires is used to sense cell voltage, and the other is used to power the device. They are separate so no current is drawn on the wire used to measure. Because of this, it is important that the jumpers on J2 (RL+) and J6 (RL-) are removed so the two wires on the top and bottom are not connected.
