LifePo4 Batteries

We believe your choice for lithium iron phosphate batteries should be driven by 3 factors – Price, Value, and Expertise. 

Price – GLine batteries are made with the the best Grade A lithium iron phosphate cells available on the market combined with a BMS designed specifically for marine applications. As fishermen ourselves, we understand the costs involved in a LiFePO4 upgrade. We pride ourselves in being one of the few high grade marine options that offers a true cost-to-benefit LiFePO4 battery line. 

Value –  GLine batteries come with many features our competitors don’t offer. Our NEW Marine Power Packs cover both your deep cycle and starting needs, and every one of our batteries gives you enough amps for all day power. We have one of the best warranties available. We are very responsive, and available to offer assistance with any questions or concerns you might have. We also offer free installation and setup if you bring your boat to our upstate South Carolina shop. All GLine batteries come fully charged and ready to fish. Just install and go!

Expertise – Our CEO Tom developed this specific combination of cells and BMS as a solution to his own problems with traditional lead acid marine batteries, and is still running the prototypes after almost 3 years. As a pro tournament fisherman and expert in LiFePO4 batteries, he is uniquely equipped to understand and solve the specific battery needs of our fishing community.
