How To Hook Up Two 12v Rv Batteries. Step by step RV Battery WiringWarning. And yes a weaker battery will draw a stronger one down.
When connecting two batteries together on an RV trailer you usually connect the batteries in parallel to draw 12 volts from both of the batteries. Following this example where there are two 12V 200Ah batteries connected in series we will have a total voltage of 24V Volts and an. Parallel is needed to double the power that the batteries put out for use in larger RVs with a lot more electronics and series pulls equal power from both batteries but allows the batteries to run for much longer.

In parallel the voltage stays the same and in series it is doubled. This is called a parallel connection as opposed to the series connection if you want to create 24 volts from 2 12 volt batteries. If you use a microwave or home theater system you will probably need a battery. The typical RV is made to handle 12V.
