Crank. Cruise. Connect. Start your engine, power your electronics, and see it all on your MFD.

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.

Why you’ll love it

• 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.
