Rv batteries parallel or series.

Once two 6v batteries are wired together in series you can wire them to another pair of 6v. Batteries wired in this way will increase their voltage and amperage. We have a photo see photo at right that shows how to wire the batteries in parallel. 6v rv batteries need to be wired in series in pairs to create a 12v battery.

Two 12 volt batteries in parallel have twice the capacity of the six volt series but the 12 volt parallel connection is a dangerous fire and explosion hazard. Jeffery gannon october 13th 2017. The parallel setup will keep the power output the same as the batteries but it will increase your capacity for every battery added to it. 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.

Fuses or circuit breakers for each battery should be used to prevent a good battery. Connecting in series parallel requires wiring two batteries in series and wiring each pair of batteries in parallel. Two 100 amp hour 6 v batteries in series have the sam capacity as one 100 ah 12 volt battery. If four 6 volt batteries each with a capacity of 200 amp hours are wired in series parallel the result is a 12 volt battery bank with a capacity of 400 amp.

Should i wire my rv batteries in series or parallel. I recommend connecting 4 12v batteries in parallel so that you have a normal amount of power for an extended period of time.
