Lithium batteries for telecom must operate in -40°C to 60°C ranges. LiFePO4 (LFP) chemistry outperforms NMC in thermal stability, retaining 80% capacity at -20°C.

Here's the kicker: Modern LiFePO4 batteries demonstrate 98% depth-of-discharge capability, yet most installations only utilize 60-70% capacity. Why? Because existing battery management systems (BMS) can't handle the complex load profiles of massive MIMO antennas.
