1. A method of operating a wireless battery management system (WBMS), the WBMS including a plurality of cell module assemblies (CMA) each having a respective battery module and a respective cell monitoring unit (CMU), the method comprising:
storing, in a WBMS database of the WBMS, respective media access control (MAC) addresses and identification (ID) data for the CMAs;
selecting, via a wireless-enabled manager device, a batch of the CMAs to communicate with to thereby retrieve data for their respective battery modules;
generating a manager access control list (ACL) with the respective MAC addresses and ID data for the selected batch of the CMAs, wherein generating the manager ACL includes:
retrieving, via a remote computing device from the WBMS database, the respective MAC addresses and ID data for each of the selected CMAs;
creating, via the remote computing device, a text file with the respective MAC addresses of the selected CMAs; and
uploading the text file from the remote computing device to the manager device;
establishing a wireless connection between the manager device and the respective CMUs for the selected CMAs based on the MAC addresses and the ID data in the manager ACL;
downloading, via the manager device from the respective CMUs of the selected CMAs, device data for each of the battery modules associated with the selected CMAs; and
switching an operating mode for each of the respective CMUs.
