Abyss Battery 12V 150Ah Dual Purpose Lithium Marine Battery - AB-12V150-BT

The ABYSS 12V 150Ah Dual Purpose Lithium Marine Battery is engineered for serious offshore performance and all-day reliability. Now redesigned in a more compact GC2 group size, it delivers more energy density, superior safety, and advanced technology — redefining what a marine lithium battery can do.

With an impressive 150A continuous BMS and 1500A peak CCA, this powerhouse starts high-horsepower outboards with ease while sustaining extended deep-cycle performance to power your Seakeeper, radar, refrigeration, chill plates, A/C systems, and autopilot on long runs and overnight trips.

Built with the same new-generation improvements found across the ABYSS®lineup, the ABYSS 12V 150Ah GC2 is the ultimate dual-purpose lithium solution — compact, intelligent, and designed to handle everything from heavy offshore systems to everyday reliability on the water.

What our Experts Think

Q&A

Q: What is the Abyss Battery AB-12V150-BT used for?
A: A high-performance 12V 150Ah dual-purpose LiFePO₄ marine battery designed for both engine starting and deep-cycle house loads like electronics, refrigeration, lighting, and onboard systems.

Q: What are the key specifications of the AB-12V150-BT?
A: 12.8V nominal voltage, 150Ah capacity (~1.9kWh usable energy), IP67 waterproof construction, and advanced BMS with Bluetooth monitoring.

Q: What makes it a “dual-purpose” battery?
A: It delivers high cranking power for starting outboard engines plus deep-cycle energy for sustained marine electrical loads, eliminating the need for separate batteries.

Q: Does it support engine starting?
A: Yes, it provides very high peak discharge capability (up to ~1200A CCA range), making it suitable for large outboard engines.

Q: What is the cycle life?
A: Around 3000 cycles at full discharge and up to 6000 cycles at partial depth of discharge, significantly longer than lead-acid batteries.

Q: Does it include Bluetooth monitoring?
A: Yes, built-in Bluetooth BMS allows real-time monitoring of state of charge, voltage, current, temperature, and diagnostics via mobile app.

Q: What systems is it best for?
A: Offshore fishing boats, center consoles, and cabin boats needing one battery for both starting and house power systems like radar, autopilot, and refrigeration.

Q: Is it safe for marine environments?
A: Yes, it is IP67 rated and built with a marine-grade sealed LiFePO₄ design plus integrated BMS protections against overcharge, overheating, and short circuits.

Maintenance Tips

• Use proper charger profile: Charge only with LiFePO₄ charger (14.2–14.6V). Avoid AGM/lead-acid modes to prevent BMS stress.
• Avoid deep discharge: Recharge before ~20–30% SOC to maximize lifespan (up to ~3000 cycles at full DOD).
• Temperature control matters:
• Charge: 0°C to 55°C
• Discharge: −20°C to 60°C
• Respect current limits: Keep continuous discharge within rated BMS limits (~150–200A depending configuration) to avoid cutoff under engine + accessory load.
• Bluetooth monitoring: Regularly check SOC, voltage, temperature, and charge/discharge current to detect abnormal alternator or load issues early.
• Storage best practice: Store at ~50–70% charge in a cool, dry place; avoid long-term full charge storage in hot environments.
• Terminal maintenance: Inspect M8 terminals for tightness and corrosion—high current draw makes connection quality critical.
• Marine protection: IP67 sealed, but rinse salt buildup and avoid pressure-washing connectors or vents.
• Parallel/installation balance: If used in banks, equalize voltage before connecting to prevent imbalance stress.
