    Awesome On-Board Battery Charger

    So far this on-board battery charger has been amazing. could not be happier. the price was amazing. love the testing it does before charging, and seems to be keeping marine batteries at peak performance, great product.

    Good onboard charger

    Using this charger to keep three batteries charged. I have two AGMs and one normal battery, and I’m using it on the classic flooded cell profile. It got all three fully charged and on float in about 4 hours. My only complaint would be that I hoped I could use different battery profiles between the three outputs, I am stuck charging my two AGM batteries as flooded cell batteries since you cannot set them independently.

    ProMariner 44021 ProSport HD20+ 120V, 20 Amp, 3 Bank

    No more fumbling with a single battery charger to keep all 3 batteries ready for the water, come home from a fishing trip, plug in 1 charger and it charges, condition and maintain all 3 in 1 easy step. Love it so far. Time will tell on the quality but with a 3 year warranty, they must believe in it,
