HCB ER34615 Li-SOCI2 Battery precisely matches the new power supply requirements of IoT modules
In the IoT era, the intensive application of "communication standard modules", "sensor integration modules", and "function expansion modules" has made the power consumption characteristics of devices diverse more - some require instantaneous high load support for data transmission, some need long-term low power consumption to maintain monitoring, and some rely on the parallel expansion of multiple batteries. Single balanced batteries are no longer able to meet the segmented demands. HCB Battery keenly identified and took the lead in making strategic plans. After launching the "Silver Bullet" series in 2020, it immediately initiated the research and development of lithium-ferrous batteries and capacitor combination batteries. In 2024, the "Direction" series passed the medium and long-term tests. We have developed the ER34615 (Silver Bullet), ER34615D (Direction), and ER34615DH (Direction-High Capacity) series of products, adhering to the concept of "tailoring to specific needs", to strengthen the power supply defense line for IoT devices.
