Lithium Battery Upgrades for Modern Yachting

Lithium Battery Upgrades for Smarter, Cleaner Power

Unlock greater energy independence and efficiency with a custom lithium battery installation by the Smart Marine Solutions Team.

We recently completed a transformative power upgrade aboard Yacht Indulgence, a 67’ Fountaine Pajot, by installing a 2432Ah MG Energy lithium battery bank—boosting her original capacity by an impressive 3.5 times. This ABYC-compliant system was designed and installed in just seven days, delivering powerful, reliable, and eco-conscious performance.

Thanks to this upgrade, Indulgence can now run entirely on battery power—including air conditioning—for over 10 hours on a full charge. The benefits? Fewer generator hours, quieter nights at anchor, enhanced comfort, and a reduced environmental footprint.

Why Upgrade to Lithium?
Modern lithium battery systems are changing the game for yacht owners and charter operators. Here’s why switching from traditional AGM or lead-acid to lithium is a smart move:

  • Extended Battery Life & Faster Charging

    Lithium batteries last longer and recharge more efficiently than traditional systems.

  • Improved Efficiency & Load Handling

    Better performance under load keeps your systems running smoothly without spikes or drops.

  • Reduced Generator Use & Fuel Costs

    Less reliance on noisy generators means lower fuel costs and a quieter onboard experience.

  • Increased Comfort for Guests & Crew

    Air conditioning, lighting, and entertainment systems can all run silently and reliably on battery power.

  • Smart Integration with Existing Systems

    Custom installations are tailored to your yacht’s layout and power demands, maximizing efficiency.
