Upgrade to lithium batteries with proper system integration
Lithium iron phosphate (LiFePO₄) batteries offer significant advantages over traditional lead-acid: more usable capacity, faster charging, longer lifespan, and lighter weight. For cruising boats, that means more time between charges and less weight in the bilge.
But a lithium conversion isn't just swapping batteries. Your charging systems need to be compatible, your BMS needs proper integration, and the installation needs to account for lithium's different characteristics.
We handle conversions that work — not drop-in solutions that leave you with charging problems or BMS disconnects offshore.
We start by understanding your actual power needs, existing charging sources, and how you use your boat. This determines the right battery size and configuration.
Not all lithium batteries are equal. We help you choose quality cells with proper BMS, appropriate for marine use and your specific requirements.
Your alternator, shore charger, and solar need to work with lithium's charging profile. We upgrade or configure charging sources for proper compatibility.
The Battery Management System protects your investment. We ensure proper setup, monitoring, and integration with your boat's systems.
Proper mounting, ventilation considerations, fusing, and cable sizing. Lithium batteries require attention to detail in installation.
Complete testing under load and charging to verify everything works together. We don't leave until the system is proven.
Things to think about before converting to lithium.
Lithium batteries can accept charge faster than your alternator can safely deliver. External regulation or current limiting may be needed.
LiFePO₄ shouldn't be charged below freezing. If you boat in cold climates, heated batteries or charge lockouts may be necessary.
Drop-in replacements are convenient but may not be the best solution. Custom builds can offer better capacity, monitoring, and longevity.
Some older chargers and inverter-chargers can't be adjusted for lithium profiles. We'll assess what can be reconfigured and what needs replacing.
