Battery management
Intelligent battery management
Charger output power
(6250 W±200 W) x N. The maximum charge power of a
power module is 6250 W±200 W (the maximum current is
10 A). N represents the number of power modules in the
rack.
Cold start
When a mains outage occurs, batteries can start the UPS to
supply power to loads.
Charging voltage (lead-acid
battery)
Equalized charging voltage: 2.3–2.4 V/cell, 2.35 V/cell
by default (30–42 batteries); 2.3–2.35 V/cell, 2.35 V/cell
by default (44 batteries)
Float charging voltage: 2.23–2.3 V/cell; 2.25 V/cell by
default (30–44 batteries)
The UPS supports the SmartLi. For details about related parameters, see the SmartLi user
manual.
