Australian Boat Lithium Case Study Standard

A useful case study shows why a system was designed, what it cost, how it was tested and what changed after real use. A photograph of batteries in a locker is not enough.

This standard provides a consistent structure for Australian owners and installers who contribute vessel projects to the site.

Minimum vessel context

Record the vessel type, approximate length, operating area, private or commercial use, typical crew, time away from shore power and any relevant limitations such as a swing mooring, hot engine room or long offshore passages.

Owner and vessel names may be withheld. The technical context must remain detailed enough for readers to understand whether the design resembles their own use.

Before-and-after system record

Document the original battery chemistry and capacity, known problems, retained equipment and the reason for the project. For the new system, record:

• battery model, configuration, voltage and nominal kWh;
• BMS architecture and current limits;
• solar, alternator, shore and generator charging;
• inverter or inverter-charger;
• cable and protection changes;
• monitoring and alarms;
• battery location and restraint; and
• essential-service and engine-start arrangements.

Loads and design assumptions

Include a measured or carefully estimated daily load table, largest simultaneous load, autonomy target, reserve and expected charging by source. State the season and cruising region because refrigeration demand and solar yield are not constant around Australia.

Calculations should be reproducible. If the design changed during installation, explain why.

Cost and commercial disclosure

Break out battery, charging, inverter, protection, cabling, monitoring, labour and other material costs where permission allows. State the date, GST treatment and whether equipment or labour was discounted, sponsored or owner-supplied.

Do not compare a self-installed battery swap with a documented professional refit as though the scopes were identical.

Commissioning evidence

Record charge-source output, alternator temperature observations, high-load voltage drop, inverter load test, monitor configuration, alarm behaviour and any defects left open. Testing must follow the equipment instructions and must not manufacture unsafe faults.

The commissioning checklist supplies a reusable structure.

Follow-up results

The strongest case studies include updates after approximately three, six and twelve months. Useful observations include daily state-of-charge range, solar yield, engine charging time, BMS events, monitor drift, terminal inspections, equipment failures and whether the owner’s original objective was met.

Negative results are not removed. A case study that explains a mistake or later modification may be more useful than one that reports no problems.
