 The following rules must be followed when modifying the parameter values
in User for a lithium battery.
A． Over Voltage Disconnect Voltage>Over Charging Protection Voltage(Protection
Circuit Modules(BMS))+0.2V;
B． Over Voltage Disconnect Voltage>Over Voltage Reconnect Voltage＝Charging
Limit Voltage ≥ Equalize Charging Voltage＝ Boost Charging Voltage ≥ Float
Charging Voltage>Boost Reconnect Charging Voltage;
C． Low Voltage Reconnect Voltage > Low Voltage Disconnect Voltage ≥ Discharging
Limit Voltage.
D． Under Voltage Warning Reconnect Voltage>Under Voltage Warning Voltage≥
Discharging Limit Voltage;
E． Boost Reconnect Charging voltage> Low Voltage Reconnect Voltage;
F． Low Voltage Disconnect Voltage ≥ Over Discharging Protection Voltage
