Dakota Lithium DL+ 12V 640Ah Dual Purpose LiFePO4 Battery with CAN Bus

Dakota Lithium DL+ 12V 640Ah Dual Purpose LiFePO4 Battery (Model: DL+ 12V 640Ah) – High-Performance Power Solution for RVs, Marine, Solar, Off-Grid, and Automotive Applications

Unlock massive energy storage with the Dakota Lithium DL+ 12V 640Ah Dual Purpose LiFePO4 Battery (Part No: DL+ 12V 640Ah), a versatile powerhouse featuring CAN Bus integration for smart system monitoring. This battery delivers 640Ah of robust LiFePO4 power at 12.8V (7.68kWh) with 1000 CCA for engine starting, replacing up to 12 AGM or lead-acid batteries while weighing just 121 lbs—offering 6x the usable capacity at a fraction of the weight, with 5,000+ cycles at 80% DoD. Equipped with internal heating for cold-weather charging below 32°F, an advanced active BMS for safety, and CAN Bus for seamless communication with inverters, monitors, and controllers, it supports high-discharge rates up to 300A continuous, making it ideal for large RVs, marine vessels, solar banks, off-grid homes, or automotive setups requiring maintenance-free, high-capacity power.

Key Features:

  • Dual Purpose Design: 1000 CCA for reliable engine starting plus 640Ah deep cycle capacity for extended runtime in RV, marine, solar, and off-grid applications.
  • CAN Bus Integration: 9-pin port for real-time data sharing with compatible electronics, enabling external control of charge/discharge and system optimization.
  • Internal Heating Element: Automatically activates for safe charging in sub-freezing temperatures, ensuring performance down to -20°F.
  • Integrated BMS: Protects against overcharge, over-discharge, short-circuit, high temperature, and low voltage; active cell balancing for maximum longevity.
  • High Discharge Capability: 300A continuous / 600A peak (20s) / 900A CCA pulse (5s) for powering inverters up to 3.8kW or high-demand equipment.
  • Extended Cycle Life: 5,000+ cycles at 80% DoD (6,000–7,000 at 50% DoD), with flat voltage curve for consistent power output.
  • Versatile Compatibility: Drop-in replacement for multiple Group 31/8D lead-acid batteries; supports series up to 48V and parallel configurations (e.g., 4 units for 30kWh); M10 terminals with covers.
  • Rugged Durability: IP65-rated waterproof enclosure, vibration-resistant for marine, off-road, and industrial use; operates from -20°F to 150°F.
  • Eco-Friendly: Non-toxic LiFePO4 chemistry, recyclable, and zero maintenance compared to lead-acid alternatives.
  • 11-Year Warranty: Backed by Dakota Lithium's industry-leading guarantee, plus 30-day money-back.
