A lithium upgrade is not a one-size-fits-all installation.
We design lithium systems tailored to your vessel and electrical demands
Some boats require a single 36V battery for trolling applications. Others may need multiple 12V batteries for house power, cranking or dual purpose setups.
We evaluate your current system, onboard electrical demand and charging configuration to design a setup that delivers reliable performance on the water.
This is not a parts swap. It is a properly integrated marine power system.
Lithium performance depends on proper charging and system design.
We install marine rated charging systems matched to your battery configuration and ensure wiring, protection and integration are built for long term reliability in the marine environment.
Every installation is clean, secure and professionally finished.
Most lithium battery upgrades begin around $1,690 for a single battery with a properly matched marine rated charging system.
Complete systems including 36V trolling configurations and 12V dual-purpose setups typically range from $2,900 and up depending on vessel requirements and charging design.
