Dakota Lithium Vortex 12v 20Ah Battery

(10 reviews)

Summer in North Dakota is one of North America’s best kept secrets – long days, big sky, great fishing. We built this battery to make the most of the season by taking two 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, off-grid music systems, or any 12 volt electronics where you need hours of power. 12 V LiFePO4 charger included. Looking for more power?

10 reviews for Dakota Lithium Vortex 12v 20Ah Battery

Great trolling motor battery!! This battery is perfect for small trolling motors. I have a small catamaran sailboat I recently rigged with a trolling motor. This battery is great for getting me back to shore when the wind dies – definitely beats the size and weight of the car battery. This battery won’t last all day, but it motored me around for a good 30-40 minutes, which was all I was hoping for. I just bought a 2nd battery for extra run time.


Ordered the Vortex 20 for my kayak to power my fish finder. Absolutely love it!!! Charged it up and powered my electronics all day long. Would highly recommend it!!


I have brought in 127 dakota lithiums for fisherman here in Canada. Everyone has been extremely happy with them. Only had one charger go bad, which was quickly replaced. Great customer service.

This is an amazing battery setup. I currently run a Lowrance Elite TI 9 in fish finder. I have yet to hit the end of the batter and I was able to pre-fish (5hrs) and tournament fish (~8hrs) and post fish(5hrs) on one charge. Thanks for supporting OKBF and KNFW kayak tournament groups.

I installed a new lowrance elite ti9 on the bow of my boat. Having a hard time running power cables from rear battery I came accross the Dakota batteries to power unit. Best choice!
