What a beautiful piece of equipment. First class. Does a good job topping off my batteries too.

The BEST and most unique marine charger available to the market, BAR NONE! You plug it in, select what sort of batteries you have. Connect said leads to the charger and it just works exactly how it is designed to. The ability to charge two 12 volt batteries in any technology currently available and one battery as a 24 volt lithium is a great fit for any rig that runs a triple battery setup in the way I do mine. I searched high and low for a charger that was capable of multi voltage technology in a 3 bank version and many came close to my criteria, but this one was a precise fit. I'm sure others deal with the same issue I do, but have issues finding a charger like this. Hopefully this review helps. It's a pricey unit, but it's SO worth it and eliminates having to run two separate chargers if you run acid based and lithium batteries in conjunction with each other on your rig.
