Expanded SEO Topic Cluster Map

The site should use topic clusters so that search engines and readers can understand the relationship between battery sizing, vessel type, loads, installation and Australian location pages.

Cluster 1: choose the right marine lithium battery

Pillar page: /how-to-choose-marine-lithium-battery/

Supporting pages:

• /marine-battery-size-calculator/
• /marine-lithium-battery-bank-sizes/ - every bank size from 100Ah to 30kWh, compared
• /battery-capacity-guide/
• /bms-current-rating/

Cluster 2: lithium batteries by vessel type

Pillar page: /marine-lithium-by-boat-type/

Supporting intent:

• lithium battery for 30 foot yacht
• lithium battery for 40 foot yacht
• lithium battery for 45 foot yacht
• lithium battery for 50 foot yacht
• catamaran lithium battery system
• bluewater yacht lithium battery
• motor yacht lithium battery
• fishing boat lithium battery
• houseboat lithium battery
• mooring yacht lithium battery

Every vessel page should link back to load calculation, BMS, charging and solar pages rather than operating as an isolated SEO landing page.

Cluster 3: liveaboard appliances

Pillar page: /off-grid-liveaboard-lithium-configurations/

Supporting pages:

• Starlink
• refrigeration
• autopilot
• induction cooking
• microwave and coffee appliances
• washing machine
• watermaker
• air conditioning
• computers and TV
• electric galley

Use appliance pages to answer both Can I run it? and What does it cost in kWh?.

Cluster 4: charging and generation

Pillar page: /charging-marine-lithium-batteries/

Supporting pages:

• alternator charging
• DC-DC chargers
• high-output alternators
• shore power
• solar
• MPPT controllers
• wind generation
• hydrogeneration
• generator charging
• combined charging systems
• twin-alternator catamarans

Cluster 5: installation and safety

Pillar page: /marine-lithium-battery-installation/

Supporting pages:

• BMS
• fuses
• cable sizing
• busbars
• battery switches
• shunts
• battery compartments
• waterproof and IP ratings
• heat and cold
• salt and corrosion
• AGM conversion
• quote comparison
• installer questions
• Australian standards and compliance

Cluster 6: Australian local search

Pillar page: /marine-lithium-batteries-australia/

State pages should link to city and cruising-region pages. Local pages should also link back to national technical pages. Avoid creating a city page that is only a list of providers. Give each location page a useful technical angle such as tropical heat, mooring use, winter solar, catamaran solar area or offshore passage preparation.
