Hello Sai,

It is typical to only use the needed channels and to leave the others disconnected - see datasheet section 10.2.1.2 Detailed Design Procedure for more details. I haven't seen an application where the user used multiple devices to monitor the same battery cell. My concerns are around the ability to cell balance and the potential voltage accuracy errors due to this overlapping setup.

I assume that these are on the same PCB and so I don't have any isolation or safety concerns.
