Customer Development Story

Discover how we helps global customers solve real-world battery challenges through customized lithium battery solutions.

01 – Italy Smart Hotel Remote Controller Project with CE and RoHS Support

An Italian hotel automation company was developing a rechargeable smart remote controller for guest room lighting, air conditioning, curtain control, and service request functions. The product needed to power a low-power MCU, Bluetooth module, button backlight, LED indicator, and standby circuit. The customer’s previous battery could fit the housing, but the runtime was not strong enough during repeated button activation and Bluetooth pairing tests.

The customer contacted LithoTop because they needed a compact 3.7V rechargeable LiPo battery with stable output, customized wire assembly, reliable PCM protection, and European compliance support. LithoTop reviewed the remote controller’s standby current, Bluetooth activation cycle, backlight load, charging circuit, enclosure space, cable routing, and expected daily usage pattern.

After evaluation, LithoTop recommended the 652530 3.7V 500mAh Rechargeable LiPo Battery. Our engineering team judged that the 500mAh capacity provided a suitable balance between runtime and compact structure, while the pouch cell format helped the customer keep the remote controller slim and comfortable to hold.

During sample development, LithoTop customized the connector type, wire length, cable outlet direction, PCM protection, insulation method, and label format according to the customer’s assembly process. Sample batteries were tested through button activation simulation, Bluetooth pairing cycles, LED backlight testing, standby evaluation, charging compatibility checking, and installation fit validation.

Because the product was planned for European hotel projects, LithoTop also supported CE and RoHS documentation preparation for the battery project. Before mass production, both teams confirmed golden samples, battery dimensions, connector durability, electrical performance, CE and RoHS support documents, packaging requirements, and incoming inspection standards.

The final battery solution helped the smart hotel remote controller achieve longer operating time and more stable wireless performance. For the customer, this reduced charging complaints, improved guest room product reliability, and supported smoother CE and RoHS preparation for European deployment.

02 – Thailand Portable Cold Chain Temperature Logger Project with UN38.3

A Thai logistics technology company was developing a portable temperature logger for cold chain transportation of fresh food, pharmaceuticals, and laboratory samples. The device needed to power a temperature sensor, memory chip, real-time clock, LED indicator, and periodic wireless data download function. Because the product would be shipped internationally with batteries inside, the customer needed not only stable battery performance but also transport documentation support.

The customer approached LithoTop after testing a smaller battery that reduced product size but could not support the required logging duration. They needed a rechargeable LiPo battery with better runtime, stable standby behavior, customized connector assembly, and UN38.3 and MSDS support for international shipping and customer documentation.

LithoTop analyzed the logger’s sleep-mode current, sampling interval, memory writing load, LED indication cycle, wireless download current, charging method, enclosure space, and shipment requirements. Based on this evaluation, LithoTop recommended the 652530 3.7V 500mAh rechargeable LiPo battery as a compact power solution with improved runtime margin.

During prototype development, LithoTop optimized the PCM protection design, connector position, wire length, insulation layer, and battery label to match the customer’s sealed plastic enclosure. Sample batteries were tested through temperature logging simulation, long standby testing, wireless download pulse testing, voltage stability checking, charge-discharge cycling, storage testing, and installation fit evaluation.

For the customer’s logistics and export plan, LithoTop also supported UN38.3 and MSDS documentation preparation for the battery project. Before pilot production, the customer confirmed approved sample performance, battery dimensions, connector reliability, packaging method, UN38.3 and MSDS documents, and batch inspection requirements.

The final battery solution helped the temperature logger maintain stable operation throughout transportation monitoring cycles. For the customer, this improved data recording reliability, reduced shipping documentation pressure, and supported smoother international delivery for cold chain monitoring projects.
