"I bought the 24v 50ah to power my Newport on my Hobie and was extremely impressed with the quality, power output, and how lightweight the battery was. With the 24v I've never seen it below 25v after a full day. Since then I've replaced my Amped 12v 60ah with a 50ah ZPRO. I fully expected to need an additional battery to make up for the reduced size but so far I've stayed over 12.8V fishing all day running a Helix 10, a Mega 360, Livescope, and a Garmin 106sv."
