Marine Ferroresonant battery charger, 120v a/c input, 40 amp 32v output. Located at Herrington Harbour South on Chesapeake bay, it’s heavy probably not worth shipping. I bought it new 6 maybe 7 years ago, works fine no issues I just wanted a “smart” charger. Not sure of a fair price, make offer. I’m willing to drive an hour or so to deliver.More than happy to give it to anyone on a low budget trying to revive a old boat, tell me what you got.
