A PySAM 4.1.0 script running the BatteryStateful module generates different results in Windows and Mac. Test results by @sjanzou:

I was able to reproduce the result Anton received on his Mac on my M1 Max MacBook Pro and on a Debian 11 aarch64 docker container.

On the same Mac using a Debian 11 amd64 (x86_64) docker container, I was able to reproduce your Windows results shown on the forum.
