Custom BMS for Lithium Battery Packs: A Guide to Battery Protection & Communication
Aug 28, 2026
Introduction
A lithium battery pack is more than a group of battery cells connected together.
For many devices, the Battery Management System (BMS) plays an important role in protecting the battery, monitoring operating conditions, managing cell performance, and communicating battery status with the host device.
For custom battery packs, the BMS needs to match the battery chemistry, voltage, current, cell configuration, operating environment, and communication requirements of the application.
A properly designed BMS helps create a battery solution that is safer, more reliable, and better integrated with the equipment it powers.
