Lithium Storage Base Station Weight | HuiJue Group E-Site
Recent GSMA data reveals 43% of delayed tower deployments stem from lithium battery weight complications. A typical 10kWh system now weighs 68kg - 22% heavier than 2020 models.
Engineers designing 5G base stations must contend with energy use, weight, size, and heat, which impact design decisions. 5G New Radio (NR) uses Multi-User massive-MIMO (MU-MIMO), Integrated Access and Backhaul (IAB), and beamforming with millimeter wave (mmWave) spectrum up to 71 GHz.
However, the key takeaway is that lithium batteries are significantly lighter than traditional lead-acid batteries while offering better performance and a longer lifespan. For example, a 12V 100Ah lithium battery typically weighs around 25 to 30 pounds, whereas a comparable lead-acid battery can weigh upwards of 60 to 70 pounds.
For example, 4G radios are always on (e.g., transmitting reference signals to detect users), even when traffic levels don't warrant it, such as in the middle of the night. 5G base stations can analyze traffic patterns and determine periods of low data-traffic, when it may be suitable to shut down into a “sleep mode.”
Often referred to as the brain center, this includes: Baseband Unit (BBU): Handles baseband signal processing. Remote Radio Unit (RRU): Converts signals to radio frequencies for transmission. Active Antenna Unit (AAU): Integrates RRU and antenna for 5G-era efficiency. 2. Power Supply System
