Battery capacity

And if the sky is the limit, Lithium Iron Phosphate will give you more usable power for a fraction of the weight. NexGen has a 12V 200AH LiFePo4 battery for $2,389.99. A 12V 100AH version is $1245.99 and a 50AH version is $679.99. Understand that LiFePo4 batteries can be discharged much deeper than typical flooded or AGM batteries and recharge faster. They also have a 5,000 cycle lifespan.

I have dual 6V flooded cell batteries. I really would like to upgrade to a Lithium battery, but that is a little out of reach still.

Dennis, the direct current side if an RPod electrical system s 12 volts.  If you connect two six volt batteries in series it makes 12 volts.  The advantage of this is you can increase the storage capaity of your battery by doing this and therefore the length of time the charge will last when you are using it.

You need to learn more about electricity before you start making these changes and additions.  If you can find a mentor close to where you live that can help you that would be the best.  As another poster said you need to understand the system or you could wind up damaging your Pod or worse hurting yourself or others.

Thanks for all the helpful tips.

I guess that's a good point. A pair of 12V batteries in parallel or using one as a spare would be more fail safe than a pair of 6V batteries. If one of the 12V batteries dies, the other one could still be used. The added bonus of having an emergency backup for your tow vehicle is something that I had not considered. If one of the 6V batteries goes out on you, you are stuck.
