Charger for on trailer or shore power

[SkaterRace]

I have a center console that is pretty new with dual batteries. It has a selector in the bilge area. I keep it on a trailer currently and am looking at part time leaving it in a slip. Looking for a power solution to plug it in and keep the batteries fresh and good to go. I think they got down too low and now the engine won't start at all.

What would be a good solution that I could ideally do myself as someone who is terrible with tools and electrical is scary for (colour blind).

Once a Bat goes to low it's usually damaged and needs to be replaced. If it won't charge back up then it's gone

With Bat switch off there should be no draw, if you have some then might be the ALT.

Doesn't make any difference for a shore power charger, trailer or floating. If you plug in floating need to worry about galvanic corrosion but if its protected then all good. If have outboards just get them out of the water

I don't think the batteries are **** I've had this before and they are low but likely not enough to damage them. Will have to test and see once I can charge them.

Didn't know if a charging system for a slip vs a trailer would be different. Seems like just need a shore power plug and then should be good. What should I get for the rest of it or should I be asking my mechanic?

No difference, choose one that meets the needs and amount of banks.

If both Bats come in full charged then only need 2 bank maintenance type, maybe 10 Amp.

If one Bat is low, maybe trolling , then maybe 20 to 30 Amp 2 bank. Just search on web for what is needed

Something like this NOCO charger/maintainer is pretty much foolproof:

I have one and it keeps the batteries in good shape, whether they need charging or just maintaining. I leave it hooked up all the time, except when I'm out on the water. I open the hatch and plug it to an extension cord, but you can buy fixtures that allow you to have a plug on the exterior of your boat.

Good to know that one works well I bought it that day as a temporary thing till I could solve it long term. What kind of plug do you mean?

This is what I was referring to:

I don't have one (yet); I just open the sunpad hatch and reach in with an extension cord. The waterproof receptacle plug would make things easier, but the charger works fine without it.

Thank you! That is perfect and better than what I had been thinking of doing
