Installed 6v batteries in freedom elite class C under steps

We had only one 12 V battery came from factory in our 2017 towards freedom elite 30 fe. The battery was under the steps. I could have gone with 2 12 V batteries to make my life simple. Instead I chose to go with 2 6 V batteries in series. It was a challenge to fit them Under the steps. Did some modifications and made it work. I Installed Duracell deep cycle batteries from batteries plus for less than $250. My amperage hours now 470. As they are deep cycle I think I can still get to 220 out of them at 50%.

I believe your amp hours are about 235 or half of your stated 470. You put two 6v 235 amp hour batteries in series to get 12v. What you get is 235 amp hrs at 12v. The upside is that you can drain them down 50% and get them back up hundreds of times, unlike the so called 12v Deep Cycle Marine batteries which will crap out in a short time with that kind of abuse.

What modifications did you have to make; in order for them to fit?
(Did you take any pictures?)

Not sure if Iím correct. I have 2 6 V golf cart batteries with 235 amp each battery. When I put them in series that makes 12 volt system with total of 470 amps. All Deep cycle batteries cannot be drained all the way. And mine is deep cycle so I was guessing to get 235 amp hours out of them before draining them all the way. And if I had to 12 V batteries that will give me close to 200 amp hours. So if I donít want to drain them all the way I should be able to get at least half of the amp hours before draining them Now It will be a complete different story if I have a Agms or lithium batteries as you can drain them lower and they charge faster. That I will do on my next battery change. Hopefully I should get couple years with what I got.
Please correct me if I am wrong.

Reread my post. You have a total of 235 amp hours available at 12v, not 470. Of the 235, you can take them to 50% of that, roughly. You made a wise choice with the golf cart batteries over the 12v "Marine Deep Cycle" batteries. You have increased you capacity more than double that of a single 12v battery, and the golf carts are made to take severe discharges and bounce back.

Oh, while you are at it, keep a close eye on your water levels in the batteries. The golf carts tend to be thirsty.
