-  * common example:  2 12v, 90Ah batteries in parallel = a 12v, 180Ah battery bank.   This is not a recommended configuration.  It is not due to any shortcoming of parallel connections;  [[electrical:12v:deep_cycle_battery#chain_store_batteries|12v "deep cycle" or marine batteries]] are rarely real deep cycle batteries and suffer from the treatment van life dishes out.
