Dakota Lithium Vortex 12 V 50 Ah Battery

(6 reviews)

Summer in North Dakota is one of America’s best kept secrets – long days, big sky, great fishing. We built this battery to make the most of the season by taking five of our award winning 10 Ah batteries wired in parallel, and adding a shock absorbent and waterproof, double neoprene outer shell. Combined with 2 universal connectors, this battery is built for rugged and wet conditions where you need dependable power. Prefect for 12 volt trolling motors for full day adventures, off-grid music systems, or any 12 volt electronics where you need hours of power. 12 V LiFePO4 charger included.

6 reviews for Dakota Lithium Vortex 12 V 50 Ah Battery

Excellent battery for my 12v trolling motors. Very fast delivery. A couple of small issues..dealt with professionally. Thanks!


Vortex 12 volt 50ah battery. I bought the Vortex 12 volt 50ah battery to power my large fishfinder, phone charger and lights on my fishing kayak. It has not disappointed! There is enough power for several days of fishing. One of my better investments and highly recommend for anyone needing reliable power.

It is costly but worth it. Used it on a kayak paired with a Lowrance 9″ Elite Ti2 for 10 days in Canada, no charge or solar charge and left with 12.8v left. Ran it probably close to 80 hours or more. I bought 3 10mAh at the MN ice show years back, these are absolutely worth the cost. No worry about conserving battery to make the finder last the weekend….or the week. The battery got soaked in rain, beaten with waves and had no issues. I plan to use this on my duck hunting kayak with trolling motor this fall and am confident it won’t disappoint.
