Two 12 volt batteries in parallel doubles the amp-hours but the voltage stays the same at 12 volts which is what we want. Three cells in the 6 volt battery and six cells in the 12 volt battery.
The proper way to connect two 6 Volt RV Batteries is something every RVer should know how to do.
2 6 volt batteries for rv. We installed two new deep cycle golf cart batteries for 225ah capacity at 12 volts a 3000 watt pure sign wave inverter and new wi. Its because youre multiplying with 6 and not 12 which is a much smaller number. With two 6 volt batteries ALL the charge or discharge current passes through BOTH batteries and is equal resulting in both working equally.
Step 1 Connect two 6 volt deep cycle batteries together in series see diagram 1 Note battery system voltage doubles. Brief summary as to why two 6 volt batteries are better for dry camping than one or two 12 volt deep cycle batteries. Ill go through each of these wiring methods below.

And I was ready to buy 2 new Trojans for 300. To produce a 12 volt output two 6 volt deep cycle batteries must be wired in series positive to negative. It is not as robust as the T-105 but is a good value for 75 ea and a better value than the Costco 6 volt battery.
A quick Rv solar upgrade. Try to get batteries. How to Connect RV Batteries.
The six volt battery has more life cyc. RV Deep Cycle Battery 6 volt Battery for RV Trojan Pacer Battery 210 amp hour. Because most 6 volt batteries have a higher number of amp hours for each battery it makes sense to purchase two 6 volts and wire them in a series that gives you 12 volts meeting your electrical systems needs.
The 6 volt battery has more space per cell than the 12 volt hybrid so the plates are thicker and will last longer. Trojan 6 volt Pacer Deep Cycle Battery is manufactured by Trojan as an OEM battery. Two Trojan 6-volt batteries wired in series yields about 225 amps at 12-volts.
I realize the dual 6v Trojan batteries are a better choice than 2 12v OEM batteries. You will probably want to replace them with true deep cycle batteries as they can be drawn down and recharged over and over again. The more batteries you add obviously the more current youll be able to store.
You can then connect each 6 volt pair in parallel with another pair to create a larger 12 24 or 48 volt battery bank. Each 6 volt battery pair operates as a single 12 volt battery. One 6V RV battery with 225ah equals 1350 watt-hours notice that even though the amp hours on the 6V battery is much higher than the 12V battery the watt-hours end up being very close.
I estimate that I will spend 40 nights boondocking per year. Four 6-volt batteries wired into a series-parallel configuration as another example will provide about 450 amp-hours of use. Hope this helps you to understand better.
Step 2 Connect the cable leads from the RV or Trailer to the two 6 volt batteries. But since Im also buying a converter and then solar I thought I might just buy another new 12v interstate just like my OEM battery for a hundred bucks or so. How do you hook two 12 volt or 2 6 volt batteries up to an RV or motorhome.
This is called a series parallel configuration. Now when you increase to 4 or 6 batteries you get back into the same issue as with two or more 12 volt batteries. Acid batteries both contain 21 volt cells.
This video shows you the easiness of the way. Two 6 volt batteries in series doubles the voltage to 12 volts but the amp-hours do not add. Two 6V RV batteries with 225ah is 12225 which equals 2700 watt-hours.
The good news is you can combine series and parallel wiring with 6 volt batteries so you can combine 4 or more and keep the voltage at 12 for your RV but increase the amp hours. These are a combination of deep-cycle and starting batteries. The batteries your RV came with are probably RV Marine batteries.
