When you go off the grid during a Dakota winter you need to be prepared for all that mother nature can throw at you. With the DL+ 12V 280 Ah battery we built our most compact, and powerful battery yet — ready for long expeditions in your RV, extended ocean voyages in your boat, or plenty of power for your off grid system. Engineered for maximum energy density, this battery has 280 Amp Hours of capacity in a waterproof battery case the size of a single 100 Amp Hour battery. That’s 6X the amount of usable power of a single group 31 AGM battery. Plus, up to 1,000 cold cranking amps of engine starting power, making this battery the ultimate single battery solution for boats, RVs, or any vehicle where you need a house battery that can jump start your engine.
