battery charger for winter storage

[Scott Mather]

Looking for a battery charger to keep charge up during winter storage.
do not have access to 50 amp service to run built in chargers.

I have 110v, 24 volt 25 amp charger used for our boom lift, will the same thing work here?

We have 2 banks of napa commerical 8-ds, just want to charge one bank
at a time without disconnecting battery cables.

But an Optimate 6 battery maintainer and connect it directly to the battery terminals.
I own 12 motorcycles and numerous cars in addition to the Hatt, long experience has shown this to be the best option.
Do not connect it to lithium batteries, it has a desulphation cycle that can bring a "dead" wet battery back to life like magic, but will damage lithium cells.

Note: the Optimate 6 will charge one battery at a time, don't connect it to a 32v bank. You don't have to disconnect the bank, just charge one battery at a time by connecting the alligator clips directly to the battery terminals.

If there is any power available at all, you should be able to use an adapter and just run the boats battery charger.

For example, I don't have 30A service available at the yard in the winter, but I have 15A so I have an adapter, and the battery charger doesn't use all that anyway.

Verify your current charger has a float mode and what that value is.
Then find your battery spec for storage float requirement value.
If it's close, then just adapt your ships shore cord to what service is available.

24 or 32 volt.

I have small 12 and 24 volt chargers that would be easy to set up and control via Bluetooth

For example a 3 bank 24 volt smart charger with Bluetooth 16 amps total. About $200.

You should have isolation transformers on a 52. Just plug into the 120v plug in the yard (15, 20, or 30 amp) and adapt into your 120v 50a plug on the boat. Then your transformers will give you 230v for your existing charger (or whatever you need for your current on board charger). Don't go buy something else. You what you have. I've done this many times.

Check out the NOCO battery chargers. The batteries only need the amps put in that they discharge from sitting so almost any charger amperage will work. The NOCO chargers are pretty advanced little units. They have a 'repair' function meaning equalization, power function and settings for all the new and existing battery types. I have a 10 amp dedicated to my generator battery BTW this NOCO company is the company that makes the really nice battery boxes for 8D, double 8D etc.
