Customer Development Story
Discover how we helps global customers solve real-world battery challenges through customized lithium battery solutions.
01 – Korea Smart Pet GPS Tracker Project with KC Certification
A Korean smart pet technology company was developing a compact GPS tracker for dogs and cats. The device needed to support GPS positioning, Bluetooth connection, LED indication, buzzer alerts, and periodic wireless data transmission. The customer’s previous battery could fit the enclosure, but the runtime was not stable enough during outdoor tracking tests, especially when GPS positioning and wireless communication operated frequently.
The customer contacted LithoTop because they needed a 3.7V rechargeable LiPo battery with better runtime, stable voltage output, customized connector assembly, and certification support for the Korean market. LithoTop reviewed the tracker’s GPS working current, standby current, wireless transmission interval, charging circuit, enclosure space, cable routing, and target usage time.
After evaluation, LithoTop recommended the 702050 750mAh LiPo Battery. Our engineering team judged that the 750mAh capacity provided a better runtime balance while still fitting the compact pet tracker housing. LithoTop also customized the wire length, connector direction, PCM protection, label information, and packaging method according to the customer’s assembly process.
During sample testing, LithoTop supported capacity verification, GPS operation simulation, wireless pulse discharge testing, standby testing, charging compatibility checking, temperature observation, and installation fit validation. Because the product was planned for sale in Korea, LithoTop also supported the project with KC certification preparation and related battery documentation.
Before mass production, both teams confirmed samples, electrical performance, connector durability, label details, packaging requirements, and inspection standards. The final battery solution helped the pet tracker achieve more stable outdoor operation and smoother market preparation. For the customer, this improved product reliability, reduced certification pressure, and supported a more confident launch in the Korean smart pet device market.
02 – European Smart Home Controller Project with CE and RoHS Support
A European smart home brand was developing a compact rechargeable wall controller for lighting scenes, temperature adjustment, and wireless device control. The product needed to power a touch button circuit, Bluetooth module, LED indicator, memory chip, and standby system. The customer wanted a rechargeable battery that could provide stable standby performance while keeping the controller slim and easy to install.
The customer approached LithoTop after testing a smaller LiPo battery that caused short runtime and frequent charging complaints during user trials. They needed a battery manufacturer that could provide a suitable capacity upgrade, customized battery pack assembly, and compliance support for the European market.
LithoTop analyzed the controller’s standby current, button activation cycle, Bluetooth transmission peak, LED load, charging method, internal housing space, and cable outlet direction. Based on this evaluation, LithoTop recommended the 702050 750mAh LiPo battery as a compact rechargeable power source with improved runtime.
During prototype development, LithoTop optimized the PCM protection design, connector type, wire length, insulation structure, and label format. Sample batteries were tested through standby simulation, button activation testing, Bluetooth pulse discharge testing, charge-discharge cycling, storage testing, and installation fit verification.
For the customer’s European sales plan, LithoTop also supported CE and RoHS documentation requirements for the battery project. This helped the customer prepare product compliance materials more efficiently before entering pilot production.
Before production approval, the customer confirmed approved sample performance, battery dimensions, connector reliability, packaging method, CE and RoHS support documents, and incoming inspection standards. The final battery solution helped the smart home controller achieve longer standby time and more stable wireless performance. For the customer, this reduced charging complaints, improved user experience, and supported smoother European market entry.
