    Number of batteries

    My past experience with Hydraulic levelers and slideouts has been that the system really needs two batteries. My 2021 Solitude only came with one battery.

    Is this normal?

    Yes. The dealers are responsible for batteries and unless you specified the number or type of batteries during your purchase negotiations 1 is all you typically get. I think most dealers use Interstate group 24.

    It's totally up to the dealer that you bought it from. The trailers leave the factory with no battery installed in them. When the dealers receive the unit and do their prep work to get it ready for sale, they are the ones that put in a battery or....if you request it during the negotiations process, two, four, whatever. They also are the ones that fill the propane tanks when the trailer arrives. Hope this helps.

    Solitude and Momentum call out for Group 27 batteries, if you read the owner's manual.

    We put 27's in Reflections also.

    On the same battery topic....does anyone know the approximate drain on the battery from running slides in and out. I got 3 or 4 slide run in/outs on my battery before it was done (both hydraulic and the Schwintek). I'm trying to figure out of I have a bad battery.

    FWIW, the trailer had only been plugged in for two days before this. I have to assume it was fully charged, but I'm not sure.

    Thanks!

    Your question is simple enough but the motors are not the only consistent draw. I don't have specifics since those motors are specific to the slides you have, however I recently was running the numbers when upgrading to a new battery configuration and I found rough numbers from a couple forums like this one ->https://www.rv.net/forum/index.cfm/f...print/true.cfm


    So, if the motors are around ~13amps, and you run them for lets say 60-90 seconds, you can calculate amp hours roughly.


    That stated, I've had bad/abused batteries not holding a charge and they still were able to power my slides when I boondocked, so yes I think you either have a battery with bad cells or your converter isnt working. I will tell you that the traditional lead acid flooded marine batteries do not fair well when drained past 50% capacity and won't recharge to their stated amp hour capacity. Not to go on a rant about lousy service departments, but the last three services I had at the dealer, they left the battery connected and a light on because I've had a completely dead battery when I picked it up. From the research I did, you significantly reduce the capacity of a battery just running it down once. If you want specifics on the degradation rates, there are tons of sites/forums out there that talk about the specifics. I was really shocked to find out how much damage running a battery down just one time causes. That's why it makes sense when I read about upgrading to AGM and Lithium batteries that are 2x-5x more expensive, it is those types of batteries ability to retaining charging capacity when drained.

    FWIW, I dumped the battery that came in my trailer for a set of 6v golf cart flooded batteries.

    How much better do you find the golf batteries to be? What kind of battery did you replace?

    Only had one trip out overnight but so far so good. I had a Deka 27M from the dealer. The upgrade tripled my Ah.

    Read about the different types of batteries.
    Think about where you will / want to camp. Power post or maybe no power post.
    Do you have the residential frig? You will need a bigger battery bank.

    I purchased 2 group 31 AGM batteries and 6 months later decided to go with 4 100AH lithium batteries / plus a small solar array. Don't do it twice like I did. KEN
