A **battery pack** is a collection of multiple batteries arranged together to provide a specific voltage and capacity, typically used to power various electronic devices or systems. These packs are commonly found in electric vehicles (EVs), power tools, laptops, and renewable energy systems like solar power setups. Battery packs often come with built-in circuitry, such as a battery management system (BMS), that helps regulate charge and discharge cycles, ensures safety, and prevents overheating or overcharging. The design can vary depending on the application, but the pack’s main purpose is to store and deliver power efficiently while maintaining longevity and performance.
