As shown in the battery circuit illustration, what would be the nominal output voltage and capacity of the battery bank if the batteries individually were 12 VDC lead-acid batteries rated at 100 ampere-hours each? See illustration EL-0071.
⢠Series vs. parallel battery connections and how they affect voltage and ampere-hours ⢠How voltage adds in series while capacity (Ah) stays the same ⢠How ampere-hours add in parallel while voltage stays the same
⢠Trace the wiring: is each batteryâs positive connected to the next batteryâs negative, or are all positives tied together and all negatives tied together? ⢠Count how many individual 12-volt sources are stacked in the path between the two output terminals. ⢠Ask yourself: in this arrangement, is the current forced to flow through one battery at a time (series), or can it split into multiple paths (parallel)?
⢠Identify clearly which two terminals are the final output of the bank in the illustration. ⢠Confirm whether the batteries are in one continuous chain (+ to â to + to â, etc.) or in multiple sideâbyâside branches. ⢠Once you decide series or parallel, apply the rule: series â add voltages, same Ah; parallel â same voltage, add Ah before picking a choice.
