Dakota Lithium 12V 20Ah USB Deep Cycle LiFePO4 Battery

Dakota Lithium 12V 20Ah USB Deep Cycle LiFePO4 Battery – High-Performance Power Solution for Fishing Electronics, Outdoor Adventures, Mobility, and SLA Replacements

Engineered for extreme reliability, the Dakota Lithium 12V 20Ah USB Deep Cycle LiFePO4 Battery packs 20Ah of robust LiFePO4 power at 12.8V (256Wh) into a compact SLA-sized case, delivering three times the usable capacity and half the weight of a 12Ah lead-acid battery, with an 8x longer lifespan (up to 5,000 cycles at 80% DoD). Built for cold-weather performance down to -20°F, it includes built-in USB-A and USB-C charging ports for on-the-go device powering, a convenient voltmeter, and an active BMS for safety, supporting up to 20A continuous discharge. This drop-in replacement for UB12200 and similar SLAs is perfect for high-amp electronics like Garmin fish finders, ice augers, kayaks, amateur radios, or mobility scooters, ensuring all-day runtime without maintenance.

Key Features:

  • Enhanced Capacity in SLA Form: 20Ah LiFePO4 in a 12Ah SLA case for 3x longer runtime and 75% more usable power than lead-acid equivalents.
  • Built-in USB Charging: USB-A and USB-C ports for direct device charging, plus a voltmeter for real-time monitoring.
  • Active BMS Protection: Safeguards against overcharge, over-discharge, short-circuit, and thermal issues; ensures cell balancing for maximum longevity.
  • High Discharge Capability: 20A continuous / 50A peak (300ms) for powering devices up to 256W or high-draw electronics.
  • Extended Cycle Life: 5,000+ cycles at 80% DoD, with ultra-low self-discharge for reliable standby power.
  • Versatile Compatibility: Drop-in replacement for UB12200 and many SLA batteries; supports series/parallel configurations (up to 4 units for 48V or 80Ah); F2 terminals.
  • Rugged Durability: IP65-rated waterproof enclosure, vibration-resistant for marine, outdoor, and off-road use; operates from -20°F to 140°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.
