Three major model systems driven by high-rate batteries
Ship models, car models, and aircraft models constitute the core areas of electric models, and their power systems all rely on special high-rate lithium batteries. Unlike traditional civilian batteries, these batteries must meet the three major technical requirements of continuous high-current discharge (above 50C), high energy density, and stability under extreme working conditions. Professional battery manufacturers such as Gens Ace provide core power solutions for this field.
