ABYSS® 12V 150Ah Dual Purpose Lithium Marine Battery

It suits boaters seeking compatible engine-starting capability and more stored energy for substantial 12V electronics and house loads. The GC2 format is useful when the installation needs capacity in a relatively compact footprint.

Plan the bank around the actual equipment schedule, including refrigeration, pumps, navigation and other connected loads. Starting reserve and charging availability matter as much as the capacity printed on the battery.

It is designed for dual-purpose service, including compatible engine starting. The correct match depends on the exact outboard, its minimum battery requirements, the charging system and the battery-switch arrangement.

Ask your dealer to verify the engine manufacturer's requirements against the current ABYSS specifications. Do not use horsepower or a headline pulse-current number as the sole basis for approving a starting-battery replacement.

The battery can supply compatible onboard loads within the battery and installation limits. Whether it meets your overnight needs depends on each device's average draw, duty cycle and hours of operation, as well as any engine-starting reserve.

Add up the expected consumption before selecting the bank. High-demand equipment and inverter loads also require a separate check of continuous current and startup demand; capacity alone does not establish compatibility.

Verify the complete case dimensions and terminal height against your compartment. A GC2 label describes the format, but it does not guarantee that an existing lid, hold-down or cable arrangement will clear the installed battery.

Use a correctly sized tray and restraint on a sound mounting surface, with protected terminals and supported cables. Confirm the mounting accessories required for your order rather than assuming a tray is included.

For shore power, use a compatible 12V LiFePO4 charger set within this model's specified charging limits. For engine charging, verify the alternator, regulator and any combining or isolation equipment as a complete system.

A larger battery can accept more energy without requiring a higher charge rate. Choose charger output around the battery limits and available recharge time, then verify actual charging during commissioning.

This Bluetooth model supports local monitoring through the compatible ABYSS battery app. Available readings help you track charge, current, voltage and diagnostics from a nearby supported phone.

A chartplotter needs a supported marine-network data connection. If helm-display integration is part of your project, specify that requirement when selecting the battery; Bluetooth connectivity alone does not establish NMEA 2000 compatibility.

The feature is intended to provide access to retained energy for an emergency starting attempt when the battery has entered its reserve condition. Have your installer demonstrate the correct procedure for the battery supplied.

Keep a planned reserve during normal use and recharge after an emergency attempt. A reserve button cannot correct an incompatible engine, damaged wiring or a battery fault, so repeated starting difficulty needs diagnosis.

Approved series and parallel configurations are supported within the model's published limits. Use matching batteries and a charging arrangement designed for the final system voltage and capacity.

Your installer should establish the required charge balance before connection, protect each circuit appropriately and confirm that all connected equipment suits the completed bank. Avoid adding a new lithium battery directly to an existing lead-acid bank as a shortcut to more capacity.

The battery includes a BMS and internal heating for cold-weather charging. Follow the specified temperature and charging limits; a protective shutdown is a reason to check the operating conditions, rather than repeatedly trying to reset the battery.

At handover, verify charging, app operation, secure mounting and protected connections. Inspect the installation periodically and follow the storage instructions. A sealed lithium battery still requires care of its external wiring and mounting.
