When selecting User, the battery type is to be self-customized, and in this case, the default
system voltage parameters are consistent with those of the sealed lead-acid battery. When
modifying battery charging and discharging parameters, the following rule must be followed:
Over-voltage cut-off voltage＞ Charging limit voltage ≥ Equalizing voltage ≥ Boost voltage
≥ Floating charging voltage ＞ Boost return voltage;
Over-voltage cut-off voltage ＞ Over-voltage cut-off return voltage;
Low-voltage cut-off return voltage ＞ Low-voltage cut-off voltage ≥ Discharging limit
