+Electrical components like [[electrical:12v:deep_cycle_battery|batteries]] and [[electrical:solar:panels|solar panels]] can be used independently or combined.  If combined, they are connected //in series// or //in parallel//.((more complicated arrangements are possible;  see below))
+**Series** connections **double the voltage** while the current (or capacity in Ah when dealing with batteries) remains unchanged.
+  * common example:  2 6v, [[electrical:12v:battery_capacity|200Ah]] [[electrical:12v:deep_cycle_battery#v_golf_cart_batteries|golf cart batteries]] in series = a 12v, 200Ah battery //bank//.((a bank acts as a single unit, not as two separate batteries)).  This is a recommended configuration.
+  * less common example:  2 12v, 90Ah batteries in series = a 24v, 90Ah battery bank.
+**Parallel** connections **double the current** while the voltage remains unchanged.
+  * 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.
+===== notation =====
 When discussing multi-battery banks it is common to describe the electrical layout with a particular notation.
