Abyss Battery  24V 110Ah NMEA 2000 Dual Purpose Lithium Marine Battery - AB-24V110

Built for serious boats and serious engines, the ABYSS BATTERY 24V 100Ah is a true dual‑purpose lithium battery that combines 24‑volt starting authority for large diesel engines with deep‑cycle stamina for today’s power‑hungry electronics. With NMEA 2000 compliance, IP67 marine sealing, and a unique 4‑terminal case that simplifies rigging, it turns your electrical system into a clean, connected, confidence‑building upgrade.

Features                    

• 24V Starting Authority – High‑pulse discharge for large 24V diesel engine starts—with stable voltage delivery for sensitive ECUs and MFD networks. (Verify engine cranking/MCA requirements.)

• True Dual‑Purpose – One bank that confidently cranks engines and runs house loads—radar, CHIRP sonar, MFDs, pumps, lighting, comms, and more.

• NMEA 2000 Smart Integration – View live state of charge, voltage, current, temperature, and status alerts* on Garmin®, SIMRAD®, Raymarine® and other compatible MFDs.

• IP67 Marine Toughness – Dust‑tight and protected against temporary immersion (1 m up to 30 min)—ready for spray, washdowns, and rough seas.

• 4‑Terminal Case Advantage – Four posts let you dedicate connections (engine start, house panel, chargers, accessories) without stacking lugs—cleaner installs and fewer voltage drops.

• 2.5 kWh Class Capacity – ≈2.56 kWh on board (25.6 V × 100 Ah) for long runtimes without the sag of lead‑acid.

• Advanced BMS Protection – Guards against over/under‑voltage, over‑current, short‑circuit, and temperature extremes; designed with engine‑start‑safe pulse handling.

• Lower Current at 24V – Higher system voltage means less current for the same power, helping reduce cable size and voltage drop on long runs.

A: It can deliver high cranking power for 24V diesel engine starting while also providing stable deep-cycle power for continuous onboard electrical loads.

Q: Does it support NMEA 2000 integration?
A: Yes, it connects to NMEA 2000 networks, allowing real-time battery data (state of charge, voltage, current, temperature, and alerts) to display on compatible marine chartplotters.

Q: How much power does it store?
A: Around 2.8kWh of usable energy, enabling long runtimes for marine electronics and extended offshore operation.

Q: What is the discharge capability?
A: Up to ~100A continuous discharge with high surge and cranking capability (up to ~1000A peak depending on configuration).

Q: What boats is it best suited for?
A: Offshore and commercial vessels using 24V systems that need a single battery solution for engine starting plus house power management.

Maintenance Tips

• Use correct charging profile: Charge only with LiFePO₄ charger (CC/CV ~28.4–28.8V). Never use lead-acid/AGM settings (causes imbalance and BMS stress).
• Avoid deep discharge: Recharge before ~20–30% SOC to protect cycle life (2000+ full-depth cycles).
• Temperature-safe operation:
• Charge: 0°C to 55°C
• Discharge: −20°C to 60°C
• Monitor via NMEA 2000: Regularly check SOC, amps, voltage, and temperature on your MFD to catch alternator issues, parasitic drain, or overload early.
• Respect load limits: Stay within ~100A continuous discharge; avoid sustained high loads beyond design rating to prevent BMS cutoff.
• Terminal & 4-post system care: Inspect and torque terminals regularly—this battery supports multiple dedicated connections, so loose lugs can cause heat and voltage drop.
• Marine corrosion control: Even with IP67 sealing, rinse salt buildup and keep all connectors dry to prevent resistance buildup.
• Storage best practice: Store at ~50–70% SOC in a cool, dry place; avoid full charge storage in heat.
• Parallel system discipline: Only parallel batteries at equal voltage/SOC to avoid imbalance stress on BMS.
• Engine start safety check: Periodically verify crank readiness and BMS pulse response if used for diesel starting systems.
