DL+ 12V 315Ah LiFePO4 Dual Purpose Battery

DL+ 12V 320Ah Dual Purpose Battery by Dakota Lithium
Compact Form. Massive Power. Built for Anything.

The DL+ 12V 320Ah battery is Dakota Lithium’s next-generation power solution, built to deliver maximum performance in a space-saving form. Designed for long-term off-grid use, this battery powers everything from RVs and boats to solar systems and electric vehicles, all from a durable, waterproof Group-31 case.

Inside, it packs 320 amp hours of deep cycle capacity—offering six times the usable energy of a traditional AGM battery—alongside up to 1,000 cold cranking amps of engine-starting power. This makes it a true dual-purpose battery, capable of running house systems and starting engines with a single, self-contained unit.

Despite its high capacity, the battery is compact enough to fit most Group-31 battery trays. The base dimensions are standard, but the wider top requires a quick check for compatibility with certain battery boxes. Its reinforced marine-grade housing is built to endure salt, heat, vibration, and rough handling, making it a dependable choice for high-demand environments.

Built on Lithium Iron Phosphate (LiFePO4) chemistry, the DL+ 320 offers significant advantages over lead-acid alternatives. It delivers more power, lasts up to eight times longer, and is far safer thanks to thermal and chemical stability. With a lifespan of 5,000+ charge cycles and virtually no maintenance required, it’s engineered for serious lifetime value.

Ideal for use in marine applications, off-grid solar systems, long-haul RV setups, and electric conversions, this battery offers the rare combination of engine cranking power and long-term energy storage in a single unit. It’s also fully waterproof, internally heated for cold-weather charging, and backed by an 11-year warranty.

Whether you’re heading deep into the wild or upgrading your existing system, the DL+ 320 is built to deliver stable, reliable, high-output energy anywhere your journey takes you.
