Charger seems like a quality build. Purchased and installed on my boat after being recommended by a marine tech in the area. I added the master volt remote unit as the charger was installed below decks and would be tough to monitor. Used blue sea ANL 35 amp fuses on the outputs and a blue sea grounding buss bar in the install. Works great so far. Happy with the purchase. Hoping for good life from my new AGM batteries with help from this charger.Edit to update: After almost a year and a half I'd have to ask myself why I never had one of these on past boats. This is on a trailer boat so I leave the shore power plugged in with a timer inline between the extension cord and the 30amp adapter. After letting the charger top off my batteries initially, I let it run 30min every few days with the timer. Batteries are still as new. Ready to go when I am. The Mastervolt remote control has a nice screen to show the state of charge and current voltage from where ever you mount it, I put mine in the cabin next to the 110V electrical panel, so you don't have to pull hatches to see what's up. Highly recommend.
