It replaces the two 12V lead-acid or AGM batteries normally wired in series for a 24V system, so you get a full 24-volt setup from one unit instead of two.\u003c\/p\u003e\n\u003cp style=\"font-size: 18px;\"\u003eFor anglers, that means less weight in the boat, more usable space, and steadier power through the day. Lithium iron phosphate holds a consistent voltage as it discharges, so your motor keeps its thrust deep into the charge instead of fading in the afternoon the way a lead-acid battery does.

With 100Ah of capacity, 2,560 watt-hours of energy, and a rated 4,000+ charge cycles, the Goliath is made for full days on the water and years of seasons.
