Battery Control Parameters
All the coefficient is referred to 25℃, and twice in 24V system rate, triple in
36Vsystem rate and quadruple in 48Vsystem rate.
Battery Type
High Volt Disconnect
Charging limit voltage
Over Voltage Reconnect
Equalization voltage
Boost voltage
Float voltage
Boost return voltage
Low voltage reconnect
Under voltage recover
Under voltage warning
Low voltage disconnect
Discharging limits voltage
Equalize duration
Boost duration
NOTE：
1) When the battery type is sealed, gel, flooded，the adjusting range of
equalize duration is 0 to180min and boost duration is 10 to180min.
2) The following rules must be observed when modify the parameters value in
user battery type (factory default value is the same as sealed type)
a. High Volt Disconnect > Charging Limit Voltage ≥ Equalization Voltage ≥
Boost Voltage ≥ Float Voltage > Boost Return Voltage;
b. High Volt Disconnect > Over Voltage Reconnect;
c. Low Voltage Reconnect > Low Voltage Disconnect ≥ Charging Limit
Voltage;
d. Under Voltage Recover > Under Voltage Warning ≥ Charging Limit Voltage;
e. Boost Return Voltage > Low Voltage Reconnect;
