Note 1: The maximum charge current is a function of the measured battery temperature and represents the limit where the regulated charge mode will be
activated. See section Charging for more details. The values are given for BMST software version 0.57 and later.
Note 2: The maximum discharge current is a function of the measured battery temperature and represents the limit where the battery will not discharge if
exceeded. See section Discharging for more details. The values are given for BMST software version 0.57 and later.
