Just got a 2025 M series and want to maintain batteries when stored. Do I need to disconnect them or charge with battery switch off.
Thanks
 
You can also use a battery maintainer / trickle charger . I use a Noco Genius5, 5A on a car I don't drive in the winter.

I have the Noco Genius GenPro 10x2. I just use the AB disconnect switch, actually disconnecting all the wires AND then getting them back correctly seemed challenging after missing my Benny for 7 months!!! LOL. I used a cutting board to mount the charger with the weight on the floor, then fastened with a few small bolts.

Welcome to the forum Don. I have a Promariner onboard battery charger with an external plug. Just run an extension cord to it and it'll automatically charge, condition, and maintain your batteries......

Welcome to the family, Don! Feel free to post some pictures of your new Benny.

When you talk about maintaining the batteries when stored, what exactly do you mean? A couple of weeks? Off season?
 
any recommendations on chargers/maintainers that run off a small solar bank?
i use 4 of these. 1 on the each of the boat batteries, and 1 on the generator that powers my lift. I typically don't get enough engine time to charge the boat batteries. (I live right by the sandbars) The generator is a tempory fix untill the dock power is repaired from last years storms. The generator also does not run long enough to make up for the start drain. The 4th one charges a battery for a storage unit lighting. Never any issues with any of them.


 
That is so inexpensive that I worry something is wrong with it, like it is missing the controller, but it seems to have everything.

thanks! no power at my dock, and we are only able to make it out on weekends, and not every weekend... i like the extra peace of mind charging....

I got a very similar set up off Amazon last fall for this upcoming season. I have yet to use it. For me, I wanted something that could provide an “assist” for the house battery that the Sea Legs are connected to during times of extended none use. I am hoping having my similar solar panel kit available will be a nice benefit.

I pull my batteries and put them on a trickle charger for the winter. Takes 15-20 minutes to reconnect and you have fully charged batteries when you take your boat out of dry storage.

i do the same actually.... for me its the time between uses that i need to stay topped up. i have middle toon storage and a bilge pump that can drain things when i get a lot of rain, and/or don't get out on the water frequently enough...
