Hello Paul,

Use 2X cell design capacity because of your 2P configuration.

The other values should be programmed to match each individual cell, the gauge will use the series cell count to divide the pack voltages and find the cell voltages.

What mode will the gauge be operating in?

Sincerely,

Wyatt Keller
