Custom Lithium-ion Battery Packs

Battery packs are any number of individual batteries arranged in series or parallel to provide required power to electronic devices. When designing a battery pack the specific application will dictate the required voltage and current. Individual cells can be scaled up and down and used in different combinations to create output voltages and currents that meet the needs of the application. When individual cells are arranged in series the voltage adds up. When they are arranged in parallel the currents add up. The most typical type of battery used in battery packs is lithium ion due to their high power density. The application of battery packs is wide ranging from phones to lawn mowers to automobiles.
