MK-440PC – $60
MK-3DC – $50
Both – $100
MK-40PC Has had one dead bank for about 5+ years now. After noticing the corroded ring terminals and fuse holders, there’s a chance that bank #4 actually works and only needs a new fuse holder. The 3 other banks work just fine. Just might need a new ring terminal or two.
MK-3DC Works just fine. This is meant to charge your trolling motor batteries while the big motor is running. As you can see some ring terminals are also corroded on this as well.
They have their issues but are still functional and are priced accordingly. Maybe use the MK440 as a charging your garage to keep your batteries maintained in the winter?
I’m removing these from my boat only because I bought 36V TM batteries and need a 36V charger.
I’m located in East Bethel.
