Calculating Battery Current | Information by Electrical Professionals
The cabinet says 271 amps, but I do not know if that is the string current or the cabinet current (both strings). Most of the information given on the name plate was per string.
Battery pack calculator : Capacity, C-rating, ampere, charge and
Generally, for a given capacity you will have less energy if you discharge in one hour than if you discharge in 20 hours, reversely you will store less energy in a battery with a current charge of 100 A
Battery & Power Supply Testing!
The current you see displayed is the nominal charging current being output to the battery (it should appear as a “negative” number if you''ve connected everything properly).
Specifications for Lithium-ion Battery Cabinets
NOTE: If the battery temperature is higher than the threshold after a full discharge at maximum continuous discharge power, the UPS may have to reduce the charge current to zero to protect the
