The Milliohm Problem: Why Pouch-Cell Tab Design Matters for High-Power Drone Batteries

Battery headlines usually focus on chemistry: higher energy density, faster charging, longer cycle life and safer electrolytes. Yet every ampere entering or leaving a pouch cell must pass through a much less celebrated component—the tab system. In high-power drone batteries, that narrow current path can influence voltage sag, local heat, usable power and long-term consistency. […]
