Marine Lithium Battery Upgrades and Complete Power Systems
SeaSpark Electrical provides marine lithium battery upgrades and complete onboard power systems using trusted technology. We design and install lithium battery banks, charging systems, inverters, solar integration and full monitoring setups for everything from trailer boats to cruising yachts and catamarans. Our focus is safe, reliable and efficient marine power systems that support modern electronics, extended time on the water and long term off grid capability. We supply and install all major brands, including extensive experience with Victron Energy systems for advanced marine power setups.
Why Upgrade to Lithium on Your Boat
Lithium batteries provide more usable capacity, faster charging and longer service life compared to traditional AGM or lead acid systems. They are lighter, more stable under load and handle repeated deep discharge without damage. A correctly built lithium system supports fridges, electronics, pumps, autopilots, electric cooking and extended time away from marinas. Each system is designed around your vessel to provide safe and reliable performance on the water.
Lithium House Battery Systems
We build complete lithium house battery systems for vessels that require dependable onboard power. This includes battery banks, system protection, cabling, distribution, inverter chargers and AC and DC integration. Every installation is tailored to the vessel and its requirements to ensure clean, safe and compliant power delivery across all onboard systems.
Solar and Charging Integration
A lithium system reaches its full potential when paired with the right charging setup. We design and install solar arrays, DC chargers, alternator regulation, shore power chargers and inverter chargers to keep your batteries charged efficiently. Solar layouts are planned around available space, shading and vessel design using high quality panels and hardware.
System Monitoring and Visibility
We install monitoring systems that give you clear information on battery state, charging performance, inverter loads, solar input and shore power. Whether viewing through a touchscreen, a phone app or your vessels networked displays, you can keep track of your power system at all times with accurate and real time data.
