A lithium battery pack is an integrated battery system. It is built by connecting many individual cells in series and parallel. It includes a Battery Management System (BMS), reliable electrical connections, and a protective structural package.
[pdf] For a standard 3.7V lithium-ion cell, voltages under 3.0V indicate deep discharge. Prolonged operation below this threshold degrades capacity, increases internal resistance, and may cause catastrophic failure.
[pdf] Keep lithium batteries within the ideal temperature range of 15°C to 40°C to ensure safety, maintain performance, and extend lifespan. Use a battery management system (BMS) to monitor temperatures in real time and control cooling or heating to prevent damage and thermal runaway.
