Notes
-
The above data are average values per battery measured after five charge/discharge cycles.
-
A tolerance of ±5% applies to constant power and constant current discharge values.
-
It is recommended to follow IEEE-485 standard for battery sizing, taking aging and design margins into account.
-
Voltage drops across cables should be considered during battery sizing.
