Product Advantages
Why choose the DF1920 flagship battery?

The DF1920 is equipped with fourth-generation solid-state phase change material (PCM) temperature control technology, achieving self-heating at -40℃ and active cooling at 60℃ with a 1920Wh capacity, maintaining over 95% capacity retention in extreme environments. The battery cells utilize nano silicon-carbon anode, delivering an energy density of 180Wh/kg, a 40% improvement over conventional products.

Modular drawer-type design allows hot-swapping of faulty battery modules, supporting N+1 redundant configuration. The unique "Power Bank" mode can temporarily release 150% rated power (180W/10 seconds) to meet sudden high-load demands such as medical equipment and communication base stations.

Passed military EMC anti-interference testing, operates unaffected in strong electromagnetic environments (such as radar stations, substations), and has been applied in special fields like aerospace measurement and control.
