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 voltage;
•Under-voltage warning return voltage ＞ Under-voltage warning voltage ≥ Discharging limit voltage;
•Boost return voltage ＞ Low-voltage cut-off return voltage
