The Dakota Lithium DL+ 12V 640Ah LiFePO4 Dual Purpose Battery is the most powerful and compact energy solution Dakota Lithium has ever built. With an incredible 640Ah of capacity and nearly 7.7kWh of usable energy, this single battery can replace up to 12 AGM or lead-acid batteries—delivering more power, less weight, and exceptional longevity.

Engineered with dual purpose technology, the DL+ not only provides massive deep cycle capacity but also delivers 1,000 Cold Cranking Amps (CCA) of engine starting power. Advanced features such as internal heating for cold-weather charging, CAN bus and NMEA communication, and rugged marine-grade waterproofing make it the ultimate single-battery solution for RVs, boats, off-grid cabins, and mobile power systems.

Massive Energy Storage – 640Ah capacity (7,680Wh) replaces entire banks of AGM or lead-acid batteries with a single, compact unit.
Dual Purpose Power – 1,000 CCA provides emergency starting power for large vehicle or marine engines.
CAN Bus & NMEA Ready – Smart integration for marine, automotive, and off-grid systems with included 9-pin CAN connector.
Extreme Cold Performance – Internal even-heat technology allows safe charging below 32°F, ensuring reliable operation in harsh climates.
Compact & Lightweight – Just 121 lbs, packing 6x the energy of two standard 100Ah batteries into a similar footprint.
Long Lifespan – Up to 5,000+ cycles at 80% capacity; lasts 6–8x longer than sealed lead-acid batteries.
Smart Protection – Built-in BMS safeguards against overcharge, low voltage, short circuit, high temperature, and includes external control pins for smart-grid or system automation.
Marine-Grade Construction – Rugged IP65 waterproof case for use in harsh marine and off-grid environments.
Flexible System Design – Link in parallel for expanded storage: one unit for large RVs or boats, two for off-grid homes, or four for farms and commercial systems.
Warranty Protection – Backed by Dakota Lithium’s industry-best 11-year manufacturer warranty.

Includes: Free 12V 50A LiFePO4 charger ($299 value).

This battery is ideal for off-grid cabins, farms, RVs, boats, and mobile systems that demand massive energy storage, redundancy, and the ability to power both house loads and engine starting. With CAN bus connectivity and remote terminal control, it’s also an advanced solution for smart-grid and system-integrated projects.
