PKCell Customized ER14505 Battery Packs Power IoT Innovation in Europe

Background / Challenge
In late 2024, a European IoT company needed a reliable and long-lasting power solution to support its next-generation connected devices. The requirements included:
-
High energy density and stable performance to guarantee device reliability
-
Adaptability to unique assembly requirements, ensuring smooth integration into the production line
-
Consistency in large-scale supply, with the ability to move quickly from prototypes to mass production
During testing, a key challenge emerged: the capacitor’s position within the pack design conflicted with the customer’s assembly process, requiring a redesign to enable seamless integration.
Solution
PKCELL’s engineering team quickly responded to the customer’s request. Within a short period, three customized battery pack solutions were developed using the combination of ER14505 4800mAh 3.6V and LIC1020.
-
All prototypes successfully passed performance validation tests
-
The design was re-engineered to relocate the capacitor to the negative terminal side, solving the integration issue
-
By April 2025, the customer placed their first mass production order of 5,000 customized battery packs, confirming the reliability and fit of the solution
This ensured long-term stable energy for the IoT devices and demonstrated PKCELL’s flexibility in adapting designs to real customer needs.
