LiFePO4 Batteries & Alternative Energy
Harbor Marine is bringing the power of LiFePO4 to the Key West yachting community. Cruise off-grid without compromising comfort. We can design and install a system that will allow you to sail with air conditioning, cook with electric, and even take a hot shower without ever firing up the generator!
​
Lithium energy storage is becoming increasingly popular for our cruising clients as the long term price point has become competitive with traditional lead-acid batteries. Higher capacity in less space, better performance with integrated cell balancing and remote Bluetooth monitoring; LiFePO4 is the modern solution to off-grid energy storage.
​
We offer complete system design to meet your individual needs. You will not regret choosing Harbor Marine to build your new system.

​
Harbor Marine is proud to partner with Victron Energy to deliver the highest standards in the marine industry.
