I have (32) 12 Volt batteries in series for a UPS for a voltage of 384 volts DC. The batteries are a Data Safe 12HX505. I now that with the batteries in series I have built up the voltage so the nominal current would be equal to one. I'm trying to figure out what the nominal current is? The info I have is they are 6 cell, the nominal Ah @ 8 hr rate to 1.75 volts/cell end voltage is 119 Ah and the Watts/Cell @ 15 min. rate to 1.67 volts/cell end voltage is 506 watts.
There are two of these strings in the cabinet each protected by a 400 amp breaker {(2) 400 amp breakers in cabinet}. So I have (2) strings of 32 batteries at 384 volts in each string. The name plate says 271 amps...is this 271 amps for one string or the whole cabinet. I trying to figure out the current in each string?:?
