Upgrading your sailboat or marine vessel’s electrical system can be a long and challenging process, but it doesn’t have to be! Our Marine 101 course is a series of videos that break down each step. Prior to tackling your install, it’s key to learn about the various types of batteries available for boat electrical systems and determine which one will be best for your application.  

What Types of Batteries Can Power Your Adventures on the Water? 

Before heading out on the water this season, be ready for whatever the day may throw your way with a proper power system. Whether you simply want to power navigation equipment and radio or multiple kitchen appliances and the A/C, power is an essential piece of the puzzle. The confidence of knowing you’ll have power all day long, no matter what gives you peace of mind for a relaxing day on the water.  

Although boat electrical systems can seem daunting, the Battle Born Batteries Marine 101 Guide with marine expert Connor Smith walks step by step through each part of the process. While there are multiple components to consider, first and foremost, it’s important to determine which type of batteries your system will need. This can vary depending on what you’re trying to power.

There are two main types of batteries in deep cycle house power systems on sailboats and marine vessels: lead acid and lithium. Lead acid batteries have traditionally been used in marine power systems and fall into three main categories. These include flooded AGM and gel batteries. Although they have slightly different compositions, they all have very similar charge and discharge characteristics. Lithium-iron phosphate (LiFePO4) batteries are a newer technology built into a similar form factor to their lead-acid counterparts. Some lithium batteries even offer wireless communications.
