2.5 Function overview
The BMV factory settings are suitable for an average 12V/24V lead acid
battery system of 200Ah. The BMV can automatically detect the nominal
voltage of the battery system, so in most cases the only setting which will
need to be changed is the battery capacity (Cb). When using other types of
batteries please ensure that all the relevant specifications are known before
attempting to setup the BMV parameters.
