Abyss Battery 12V 220Ah NMEA 2000 Dual Purpose Marine Lithium Battery - AB-12V220

Turn your helm into a command center. The ABYSS BATTERY® 12V 220Ah NMEA 2000‑compliant lithium battery combines true dual‑purpose performance (starting + deep‑cycle) with smart network visibility—so Garmin, SIMRAD, Raymarine, and other NMEA 2000 MFDs can display live battery status right on screen. Built in a marine‑grade IP67 sealed case and engineered with a unique 4‑terminal layout, it makes rigging cleaner, adds connection flexibility, and delivers massive, stable 12V power for modern boats.

Features                    
  • Dual‑Purpose Muscle – High‑pulse cranking for confident starts and deep‑cycle stamina for house loads and sensitive electronics.

  • NMEA 2000 Smart Integration – View state of charge, voltage, current, temperature, and health alerts* on your compatible MFD. Fewer mystery lights. More certainty.

  • IP67 Marine Toughness – Fully sealed against dust and water (survives 1 m immersion up to 30 minutes). Ready for spray, washdowns, and the rough stuff.

  • 4‑Terminal Advantage – Four posts on the case let you dedicate connections (e.g., engine feed, house panel, chargers, accessories) without stacking lugs. Cleaner installs, fewer voltage drops.

  • 2.64 kWh On Board – At 12V × 220Ah ≈ 2,640 Wh, you’ll run radar, CHIRP sonar, MFDs, pumps, lights, and comms for hours—without the voltage sag of lead‑acid.

  • Advanced BMS Protection – Built‑in battery management guards against over/under‑voltage, over‑current, short‑circuit, and temperature abuse.

  • Low Self‑Discharge – Holds a charge in the off‑season so you’re ready on launch day.

What our Experts Think    
  • True dual-purpose marine power: The ABYSS® AB-12V220 is designed to handle both starting and deep-cycle house loads, making it ideal for boats that need a single, high-capacity 12V solution.
  • Massive 220Ah energy reserve: Delivers extended runtime for onboard electronics, lighting, pumps, and accessories while maintaining strong cranking performance when needed.
  • NMEA 2000 integration: Built-in compatibility enables real-time data sharing with marine networks, improving monitoring of state of charge, voltage, and system health on modern helm displays.
  • High cranking + deep-cycle hybrid design: Engineered to support engine starts while also delivering stable long-duration discharge, reducing the need for separate battery banks.
  • Advanced LiFePO₄ safety system: Integrated smart BMS protection guards against overcharge, over-discharge, short circuits, and temperature extremes for reliable marine operation.
  • Lightweight replacement upgrade: Replaces heavy lead-acid dual-battery setups with a single compact lithium unit, improving boat performance and weight distribution.
  • Marine-grade durability: Vibration-resistant, sealed construction designed for saltwater environments and demanding offshore conditions.
  • High-efficiency power delivery: Maintains stable voltage output under load, ensuring consistent performance for sensitive electronics and trolling systems.
  • Long cycle life advantage: Rated for 3000+ cycles, delivering significantly longer service life compared to traditional AGM or flooded batteries.
  • Smart boating ecosystem ready: Designed for integration into modern marine setups, making it ideal for anglers and boaters who rely on connected onboard systems.
               
Q&A  

Q: What is the Abyss Battery AB-12V220 used for?
A: A dual-purpose 12V LiFePO₄ marine battery designed for both engine starting and deep-cycle house power, including electronics, pumps, and onboard systems with smart NMEA 2000 monitoring.

Q: What are the key specifications of the AB-12V220?
A: 12.8V nominal voltage, 220Ah capacity (~2.64–2.8kWh energy), IP67 waterproof rating, and a robust marine-grade sealed LiFePO₄ design.

Q: What makes it “dual-purpose”?
A: It delivers high pulse power for engine cranking plus deep-cycle performance for sustained loads like fish finders, livewells, lighting, and radar.

Q: What is NMEA 2000 integration?
A: It connects directly to a boat’s NMEA 2000 network, allowing real-time battery data (state of charge, voltage, current, temperature, and alerts) to display on compatible chartplotters.

Q: How much usable energy does it provide?
A: About 2.64 kWh of stored energy, enabling long runtimes for marine electronics and house loads without voltage sag.

Q: Can it start an outboard engine?
A: Yes, it is engineered for high-crank output and is suitable for starting applications where manufacturer requirements allow lithium batteries.

Q: What is the cycle life?
A: Typically 2000+ cycles at full discharge and 6000+ cycles at shallow discharge conditions, significantly outlasting AGM batteries.

Q: Is it safe for marine environments?
A: Yes, it includes an advanced BMS with protections for over/under-voltage, temperature, short-circuit, and overload, plus a sealed IP67 enclosure.

                 
Maintenance Tips  
  • Correct charging profile: Use a LiFePO₄ charger (CC/CV ~14.2–14.6V). Avoid AGM/lead-acid modes to prevent BMS stress.
  • Avoid deep discharge: Recharge before dropping below ~20–30% SOC to preserve long cycle life (>2000 cycles at full depth).
  • Temperature discipline:
  • Charge: 0°C to 55°C
  • Discharge: −20°C to 60°C
  • Never charge below freezing unless battery heating/BMS allows
  • Use NMEA 2000 monitoring: Regularly check SOC, voltage, current, and temperature via MFD to detect abnormal draw or charging issues early.
  • Load management: Keep continuous discharge within system limits (~200A class design) to avoid BMS cutoffs under heavy electronics + engine load.
  • Terminal care: Inspect 4-post terminals for torque tightness, corrosion, and heat buildup—especially on high-current connections.
  • Marine protection: IP67 sealed, but still rinse salt residue and keep connectors dry after washdowns.
  • Storage best practice: Store at ~50–70% charge in a cool, dry environment if unused for extended periods.
  • Parallel setup rule: If using multiple units, fully equalize voltage before connecting to avoid imbalance stress.
  • Regular cycling: Periodic use helps maintain BMS balance and cell health—avoid long idle at 100% or near 0%.
