Notes:
-
The above data are average values per battery and can be obtained within five charge/discharge cycles.
-
A tolerance of ±5% applies to the constant power and constant current discharge values.
-
Recommended to follow IEEE-485 Standard for battery sizing (in terms of aging margin, design margin) for optimal performance and life.
-
Considerable voltage drop across cables, if any, shall be considered during battery sizing.
