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.
*Displayed values/pages vary by MFD brand/model and network configuration.
NMEA 2000—battery data on your helm
Plug the battery into your N2K backbone and see key metrics on supported MFD pages—no extra gauges required.
Track SOC %, volts, amps, temperature, charge/discharge status and warnings (where supported) to make smarter decisions offshore.
Verify alternator/charger performance and spot parasitic draws at a glance.
Real‑world use cases
24V Diesel Start + House Bank: Start your diesel, then run radar, sonar, dual/triple MFDs, VHF/AIS, livewells, lights, and autopilot—all from one intelligent bank (with proper isolation/best practices).
Commercial & Charter Boats: Stable, quiet power for long duty cycles with helm visibility your crew can trust.
Refits & Clean Rigs: Replace two 12V series batteries with a single 24V smart pack to simplify wiring and free up space. (Confirm capacity and cranking specs for your application.)
Runtime examples (quick math)
This pack stores ≈2,560 Wh. Estimated hours ≈ 2,560 ÷ your device’s watts.
50 W electronics cluster → ~51.2 hrs
100 W cluster → ~25.6 hrs
200 W cluster → ~12.8 hrs
500 W surge/steady mix → ~5.1 hrs
Actual results vary with settings, temperature, cabling, and BMS limits.
Key Specifications
Nominal Voltage: 24V (25.6 V LiFePO₄ nominal)
Capacity: 100Ah (≈2.56 kWh)
Application: Dual‑purpose — 24V diesel starting + house/electronics
Ingress Protection: IP67 sealed marine case
Network: NMEA 2000‑compliant battery data to compatible MFDs
Terminals: 4‑post case for multiple dedicated connections
