Hello i have problem with evaluation kit. I tried to connect evaluation kit to battery pack model that was made from 13x parallel combination of capacitor 470nF and resistor 1kOhm. I wanted to measure voltage on seperated parallel combinations representing battery. I tried two wiring setups (viz. pictures in attachment). When trying to measure with voltmeter almost every cell is measured precisely by Eval kit. Only last one cell (cell1 or cell2 depending on wiring setup) is always measured with 200mV error. So i wanted to ask if i connected everything right. Thanks for answer in advance.

Hi,
Is C2 left floating ?
please refer to datasheet to take care of unmounted cells -
You can unmounted C1 instead of C2 , connect unused C1 via 1k ohm resistor to the rest .
Also, in GUI, set the VCELL1_EN = 0, so that C1 is disabled when checking diagnostics.
Best Regards
