Start big 24V diesels. Power your house loads. See it all on your MFD.

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.

Why you’ll love it

• 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.
