Discover how we helps global customers solve real-world battery challenges through customized lithium battery solutions.
Illustrative application scenario based on typical OEM development requirements; LithoTop’s KC completion for a Korean customer project is confirmed, while the application details below are representative.
Project Background: A South Korean electronics manufacturer developing a smart locker monitoring system needed a compact rechargeable battery for a wireless status-detection module. The module was designed to monitor locker activity and transmit information to a central management system without requiring a permanent wired power connection.
The product design included a compact PCB, a wireless communication module, a magnetic detection sensor, and a rechargeable battery. The manufacturer wanted to keep the electronic module small enough to install inside different locker designs while maintaining practical operating time between charging intervals.
Battery Development Challenge: One challenge was the difference between the device’s low standby power consumption and the short current peaks generated during wireless communication. Although the sensor remained in standby for much of its operating time, periodic transmissions increased the instantaneous power requirement.
The customer therefore needed to consider not only battery capacity but also the cell’s discharge capability, voltage behavior during transmission, and compatibility with the device’s charging circuit.
A second consideration was the South Korean market’s applicable KC requirements. The manufacturer needed to establish a suitable battery configuration and ensure that the relevant compliance work was addressed before final product commercialization.
LithoTop Engineering Approach: The 603035 3.7V 600mAh LiPo battery was considered as a candidate because its nominal dimensions were suitable for compact electronic assemblies.
The engineering evaluation would include battery compartment dimensions, PCB clearance, connector orientation, and cable routing. The device’s standby current and wireless transmission profile would also be reviewed to estimate practical operating time.
For a protected battery assembly, the PCM dimensions and wiring arrangement would need to be included in the final mechanical drawing. The customer would also need to confirm the charging voltage and current limits against the selected cell specification.
KC Compliance Experience: LithoTop completed KC requirements for a South Korean customer project involving the 603035 battery. This project-specific experience provides a useful reference when discussing compliance planning, technical documentation, and configuration control with other Korean OEM customers.
Sample Testing and Production Confirmation: A representative validation process would include standby-current measurement, repeated wireless transmission testing, charging verification, and battery runtime evaluation.
Before mass production, the customer would confirm the final battery drawing, connector specifications, protection configuration, approved sample, and applicable compliance documentation.
Customer Value: This development approach demonstrates how battery selection, mechanical integration, and KC-related requirements can be considered together rather than treated as separate tasks. It can help Korean OEM manufacturers establish a more controlled path from battery evaluation to product production.
Illustrative application scenario demonstrating CE/RoHS-related engineering considerations. LithoTop’s completion of CE and RoHS compliance work for another customer project is confirmed; the application and country below are representative.
Project Background: An Austrian agricultural technology developer was designing a portable soil nutrient testing instrument for field technicians and agricultural consultants. The handheld device was intended to measure selected soil parameters and display results without requiring an external power connection.
The instrument combined sensing electronics, a small display, a microcontroller, and a rechargeable power system. The customer wanted to provide enough battery capacity for repeated field measurements while keeping the device compact and convenient to carry.
Development Challenge: The instrument’s power consumption varied depending on its operating mode. During measurement, the sensing electronics and display were active. Between measurements, the device entered a lower-power state to conserve energy.
The customer needed to understand how the battery would perform under this mixed operating profile. Simply calculating runtime from the nominal 600mAh capacity would not fully account for measurement frequency, standby consumption, voltage conversion losses, or battery cutoff conditions.
Mechanical integration was another consideration. The enclosure contained multiple internal components, leaving limited space for the battery and charging circuitry. Wire routing and connector positioning therefore needed to be coordinated with the PCB layout and enclosure design.
Battery Selection and Technical Evaluation: The 603035 3.7V 600mAh lithium polymer battery offered a candidate format for the compact handheld instrument.
The recommended evaluation would begin with measuring current consumption during active measurements, display operation, and standby. These values could then be used to calculate an estimated operating profile and establish realistic runtime targets.
LithoTop could also review customized wire length, connector selection, and optional PCM protection to support the customer’s mechanical and electrical requirements.
CE and RoHS Compliance Experience: LithoTop completed CE and RoHS compliance work for a separate customer project involving the 603035 battery. For a European-market instrument, the manufacturer would need to determine the applicable requirements for the finished product and confirm whether the battery’s available documentation was suitable for the intended configuration.
RoHS-related review would focus on applicable restricted-substance requirements, while CE-related conformity work would depend on the relevant legislation and end-product characteristics.
Prototype Testing and Pre-Production Review: A representative validation program would include charging tests, operating-current measurement, runtime verification, connector inspection, and dimensional checks against the enclosure.
Before mass production, the customer would approve the battery specification, confirm the mechanical assembly, review the relevant compliance documentation, and establish production inspection criteria.
Customer Value: This scenario illustrates how a compact rechargeable battery can be evaluated for portable testing equipment while incorporating electrical performance, product integration, and European-market compliance considerations into the development process.
