Inside a Yaoqian BESS

Five Layers of Engineering Between a Cell and a Container

Every Yaoqian system is built bottom-up from grade-A cells. Scroll the stack to see how each layer adds safety, intelligence and scale.

  1. 01

    LFP Cells

    Grade-A LiFePO4 prismatic cells with in-house electrode coating — the only chemistry we trust for stationary storage.

    10,000+ cycles @ 80% DOD
  2. 02

    Battery Modules

    Laser-welded busbars and cell-level fusing keep every module balanced and serviceable in the field.

    51.2V · 5.12kWh per module
  3. 03

    Smart BMS

    Three-tier battery management watches every cell voltage, temperature and insulation resistance in real time.

    ±1mV sampling accuracy
  4. 04

    Thermal & Fire Safety

    Liquid-cooled plates hold cell temperature deviation under 3°C, with pack-level fire suppression and venting built in.

    ΔT < 3°C across pack
  5. 05

    Container System

    Factory-integrated DC/AC coupling, EMS and auxiliary power — shipped as one plug-and-play unit.
