I turned the auxiliary battery switch' to "Off" and again tested the batteries which were back at 8.5-volts. There are many pros and cons to both 6 and 12 volt batteries for RVing but it mostly comes down to preference. You can use a voltage meter whether the power is being sent to the converter charger. A parallel RV battery bank increases the current but allows the voltage to stay the same. I mention this because some shop chargers are equipped with a 6-volt output option as well as 12-volts DC. A 12-volt deep cycle battery in good condition has a reading of between 12.4 and 12.7 volts; consider a replacement battery if the reading is lower than 12.4 volts. If you have the room, you can do what a lot of RVers do and switch from the standard 12-volt batteries to two of the larger 6-volt golf cart batteries. Set your charging range up to ten amps.
