Fish longer with twice the run time, half the weight, and 8X the lifespan and reliability of traditional batteries. 60 Amp Hours (Ah) is the perfect size for most small to mid sized boats, giving you a full day on the water. For off-shore fishing, fishing in current or wind, or for larger boats the DL 12v 100 Ah, DL+ 12v 135Ah, or the DL+ 12v 320Ah is recommended. Dakota Lithium is the official battery of Bassmaster and the choice of champions like Hank Cherry, Brock Mosley, and Scott Martin.
