Why Lithium Batteries Are the Best Choice for Marine Applications
Lithium batteries have become increasingly popular in marine applications due to their high energy density, lightweight design, and longer lifespan compared to traditional lead-acid batteries. These advantages make them an ideal choice for powering various onboard systems, enhancing both performance and efficiency.
What are lithium batteries and how do they work?
Lithium batteries, specifically Lithium Iron Phosphate (LiFePO4) and Lithium-ion types, utilize lithium ions to store and release energy. During discharge, lithium ions move from the anode to the cathode through an electrolyte, generating electrical current. When charging, the process reverses, allowing the battery to regain its stored energy efficiently.
