This Dakota Lithium DL+ 12v 280Ah Battery - Group 31 is touted as the company's most compact and powerful battery to date and more than capable of running long expeditions in your boat, RV, or off-grid system. The Dakota Lithium Plus 280Ah 12V LiFePO4 Dual Purpose Battery has 280 Ah of deep cycle capacity and 1,000 CCA of engine cranking power. This system lets you start your engines and run your electronics from the same battery. This marine battery is 6X more powerful than a traditional group 31 AGM, offering 280 Amp hours of Dakota Lithium energy in a case designed to hold 100 Ah of lead acid energy. The DL+ 12v 280Ah Battery is Dakota Lithium's original 100Ah battery re-engineered for 180% greater capacity in a similar-sized case. There's no need for larger gasoline generators when you can replace them with a powerhouse condensed into a smaller 14.6' x 7.7' x 10.75' case. The incredible energy density lets you add electricity-hungry air conditioners, electric grills, or induction stovetops to your vessel. The battery temperature range is -20degF to +150degF, ideal for rugged, harsh environments. Perfect for marine/boating, solar energy, RVs, and electric vehicles, the DL+ 12v 280Ah Battery includes a LiFePO4 charger and an 11-year warranty!
