ABYSS® 24V 110Ah NMEA 2000 Dual Purpose Lithium Marine Battery

It is designed for compatible 24V engine starting and 24V house power, with battery information available through a supported NMEA 2000 marine display. Applications can include properly specified diesel-starting systems and onboard electronics, pumps or other 24V loads.

The engine, charging equipment and distribution system must all match the 24V installation. It is not a direct substitute for a battery in a 12V-only circuit.

Compare the exact engine manufacturer's starting requirements with the battery's current cranking, surge and continuous ratings. Also review the alternator or regulator, starting cables and battery-switch arrangement for lithium compatibility.

A 24V label or a description of large-diesel service is not a model-specific approval. Have the dealer or OEM document the match and verify starting and charging operation as part of commissioning.

Yes, in a compatible 24V system when its capacity and starting performance meet the installation's requirements. A single 24V battery can simplify a bank previously built from two 12V batteries, but the charger, wiring, switching and restraint must be checked for the new arrangement.

Do not add this battery in series to raise system voltage; the published specifications do not support series connection.

A 12V device must receive the voltage specified by its manufacturer. Use a correctly sized 24V-to-12V converter or a separately designed 12V supply rather than connecting a 12V-only load directly to this battery.

Include conversion losses and peak demand when sizing the system. The four terminals provide connection points; they do not create separate 12V outputs or independently isolated battery sections.

A compatible NMEA 2000 display can show supported battery information such as state of charge, voltage, current and temperature. The exact data pages and warnings depend on the display model and network configuration.

Use the specified connection equipment and have the installer configure the battery identity. Verify the desired readings at the helm during handover instead of assuming every display presents the same information.

Use compatible 24V LiFePO4 charging equipment within the battery's specified voltage and current limits. Review the engine alternator, regulator and any DC-DC equipment as part of the charging design.

Do not assume a two-bank 12V charger can be connected as it was to the previous pair of batteries. Confirm the correct charger arrangement and verify charge behavior at the battery before the boat enters service.

The four-post case provides additional connection points to help organize starting, house and charging cables. It does not remove the need for correct distribution, circuit protection, polarity and limits on terminal connections.

Check the current case dimensions and terminal layout against the compartment. Secure it with a suitable marine tray and restraint, allowing cable and network access. Confirm mounting accessories separately when planning the installation.

List the house equipment, average demand and operating hours, then reserve energy for starting and essential loads. Compare the resulting requirement with the current model's rated capacity and allowable current.

Measure consumption during commissioning to refine the plan. Equipment running through voltage converters or inverters adds losses, and high startup demand needs a separate current check; an amp-hour rating alone cannot guarantee an overnight runtime.

Demonstrate normal operation, supported warnings and what to do if the BMS disconnects the battery. Verify secure mounting, protected connections, engine starting, charging and NMEA data before handover.

Follow the model's temperature and storage limits, inspect the external installation regularly and investigate repeated faults. IP67 sealing does not replace a suitable installation or justify continued operation after flooding or damage. Record the serial number and system configuration for service.
