Describe the issue

v1.6.2 works while v1.6.3 sometimes produces 0 values as it can be seen here:

Issue is caused by clearing bytearray which is later assigned (not copied) to final version: https://github.com/patman15/BMS_BLE-HA/commit/8e9c1b7c934d6837fb3f93f2032b290c7677ed2d#diff-ce80ef634830b4483558d11765fb3faca12bf0ee435cd5f85faa072835be557dR106

Reproduction steps

1. run integration v1.6.2 using JK BMS
2. wait some time, as it is a timing related issue
