Description
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.
*Displayed metrics and pages vary by MFD brand/model and network configuration.
NMEA 2000—battery data on your MFD
-
Plug into your backbone and see key metrics on supported pages—no extra gauges needed.
-
Monitor SOC %, volts, amps, temp, charge status, and warnings (where supported).
-
Make smarter decisions offshore: spot parasitic draws, confirm charging, and time your runs.
Works with: Garmin®, SIMRAD®, Raymarine®, and other NMEA 2000‑compatible MFDs.
Real‑world use cases
-
Single‑bank simplicity: Start your outboard, then power the house system from the same battery (follow proper isolation/best practices).
-
Offshore center consoles: Drive dual/triple MFDs, CHIRP sonar, radar, livewell pumps, VHF/AIS, stereo, and lighting with headroom to spare.
-
Cabin & bay boats: Quiet, stable voltage for fridges, lighting, and electronics without generator noise.
Runtime examples (quick math)
This pack stores ≈2,640 Wh. Estimated hours ≈ 2,640 ÷ your device’s watts.
-
50 W electronics cluster → ~52.8 hrs
-
100 W cluster → ~26.4 hrs
-
200 W cluster → ~13.2 hrs
-
40 W 12V fridge → ~66 hrs
-
Starlink (50–100 W typical) → ~26–53 hrs
Actual results vary with settings, temperature, cabling, and BMS limits.
