The most important aspect of ensuring the functionality of 48V lithium-ion batteries is their safety, which is guaranteed through the use of multiple safety features. These include a battery management system (BMS) that supervises voltage, current, and temperature to control battery functions. The system also protects against overcharging, over-discharging, and thermal runaway. Furthermore, the use of high-quality construction cells, flame-retardant and proper insulating materials, add to safety. Due to rigorous safety measures, 48V lithium-ion batteries are safe to use in commercial, residential, and industrial applications without posing any risk or safety concerns to users, property, or threatened.
