I like that this charger can charge three batteries at once & I can quickly disconnect, so I don't have to worry about someone stealing it. The posts on my battery boxes were larger then the ones it came with. Not a big deal, picked up some at local auto parts store. I have to acid deep cycle batteries in my boat & will be adding a third.

Works fine. You have to set each bank to the type of battery (AGM or lithium) when you first plug it in before connecting the separate connector wires (alligator or ring terminal lines). The unit doesn’t search automatically if you hook it all up first and plug it in. It will remember the battery type thereafter for each line after you connect those terminal lines. The unit is heavy and a lot bigger than I thought it would be. It’s a good charger. It doesn’t fit in my bilge area (it’s too big), so I just attached to a 2x6 piece of wood as a handle to carry it. I use the alligator clips. No big deal as I can use as a portable charger on other batteries too. Nice charger for a decent price.
