Sea Tek Marine in Marathon, Florida offers advanced Lithium battery technology for off-grid marine systems.

More power in less space and weight.

Lithium Iron Phosphate (LiFeMnPo4)battery technology offers superior energy density, charge times, discharge capacity, and longevity all in less weight and space than conventional electrolyte batteries. The results are smaller battery banks delivering more power, or dramatically more capacity in the same space as your existing batteries.

Lithium Batteries

Our batteries come in 4-cell, 200AH packs that can be combined to suit any application. All cabling and monitoring circuitry is mounted on the ends of the packs, protected by in-molded tabs and plastic cover plates.

Integration

Lithium ion batteries differ in many ways from conventional electrolyte batteries, but that doesn’t mean integrating them into your existing systems will be a headache. While we recommend high-output chargers to get the most out of your lithium batteries, standard smart chargers and distribution systems are easily compatible with these packs. Our experienced team will be there every step of the way ┬áto ensure that your new batteries integrate smoothly into your existing systems.
