 +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))  For the following examples we will consider //two items// -- batteries, solar panels, etc.  
 + 
 +**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.

 When discussing multi-battery banks it is common to describe the electrical layout with a particular notation.   When discussing multi-battery banks it is common to describe the electrical layout with a particular notation.

 Examples: Examples:
-  * **2p1s** - two batteries in parallel, as one finds in the common 2x6v GC battery setup 
-  * **1p2s** - two batteries in series, as one finds in 2x12v 24v systems 
-  * **2p2s** - two batteries in parallel, linked in series to another set of batteries in parallel, as one finds in higher-capacity 2x2 6v setups 
   * **1p1s** - a single battery   * **1p1s** - a single battery
 +  * **1p2s** - two batteries in series, as one finds in the common 2x6v GC battery setup
