Another easy way to test 10s–16s applications is to always use the BQ76952 device as the monitor, but short
some input channels. Table 3-3 gives the guidance on how to do this with the TIDA-010208 board.

3.2 Test Setup
Use the following procedures before running this design board. The design was constructed with 16S pack
configurations, for other cell counts considerations, refer to Table 3-2 or Table 3-3 to modify the components.
The board was tested using DC source and 4900-μF electrolytic capacitor in parallel to simulate the total pack.
Sixteen 1-kΩ resisters in series are used to divide the pack voltage and simulate 16s battery cells.
