Many experienced rv owners would often upgrade their batteries to 2 x 6v batteries that are connected in series. Having two 12 volt batteries in parallel will give you twice as many amp hours capacity as two 6 volt batteries wired in series.

2 6 volt batteries to 12 volt. Discharging down do 80 depth of discharge 600 700 on average. For two 6v batteries you can connect the positive output wire in red of the charger that is 12 or more volts to the positive terminal of the first battery. Yes series the two batteries to produce 12 volts. A 12v agm battery on average has only 150. 12 volt batteries are more affordable than 6 volt ones and its super easy to connect two of them together to double your amp hours. It would appear that there is no significant difference in capacity and voltage between these two examples.
This is called a series parallel configuration. Jump start procedures preparing your batteries for winter advantages and disadvantages of using two 12 volt batteries connected in parallel or two 6 volt batteries connected in series. The 6 volt option must be used in groups of two. Then connect the negative end of the first battery to the positive end of the second one and connect the negative end of the second battery to the negative output wire in black of the charger. To produce a 12 volt output two 6 volt deep cycle batteries must be wired in series positive to negative. Two 6 volt batteries in series vs one 12 volt life cycles.
I assume they are deep cycle batteries and not car starter batteries. Each 6 volt battery pair operates as a single 12 volt battery. Amp hours are a unit of measurement commonly used to tell you how much storage your rv battery is capable of. This configuration will still provide you with 12v of voltage which is the requirement for running appliances in an rv. Most regular rvmarine deep cycle batteries will have around 70 amp hours in them but you can buy deep cycle rv batteries with much less or much more. Tap off of the two end terminals for the 12 volts.
6 volt agm battery has more life cycles. You can then connect each 6 volt pair in parallel with another pair to create a larger 12 24 or 48 volt battery bank. Tap off of the series jumper for the 6 volts of one of the batteries. Below is a collection of quick reference diagrams on hooking up multiple 6 volt and 12 volt batteries to create 6v 12v 24v 48v etc as required for energy storage systems commonly found in residential and off grid solar hydro and wind systems.
