Customer Development Story
Discover how we helps global customers solve real-world battery challenges through customized lithium battery solutions.
01 – France Smart Bike Tail Light Project with CE and RoHS Support
A French cycling electronics brand was developing a rechargeable smart bike tail light for urban commuting and night riding. The product needed to power high-brightness LEDs, an acceleration sensor, brake warning logic, Bluetooth connection, and multiple lighting modes. The customer’s early battery sample could fit the enclosure, but the runtime dropped quickly when the brake warning mode and Bluetooth connection operated frequently.
The customer contacted LithoTop because they needed a compact 3.7V LiPo battery with better capacity, stable discharge performance, customized cable assembly, and European compliance support. LithoTop reviewed the LED power consumption, flashing mode current, Bluetooth usage cycle, charging circuit, waterproof housing structure, cable routing, and expected riding time.
After evaluation, LithoTop recommended the 503450 3.7V 1000mAh LiPo Battery. Our engineering team judged that the 1000mAh capacity could provide a stronger runtime margin while still fitting the slim rear-light enclosure. LithoTop also customized the wire length, connector type, PCM protection, label format, and insulation method according to the customer’s assembly process.
During sample development, LithoTop supported LED runtime testing, brake warning mode simulation, Bluetooth pulse discharge testing, charging compatibility checking, temperature observation, waterproof enclosure fit validation, and charge-discharge cycle evaluation. Because the product was planned for European retail channels, LithoTop also supported the project with CE and RoHS documentation preparation.
Before mass production, both teams confirmed samples, electrical performance, connector durability, battery dimensions, CE and RoHS support documents, packaging requirements, and incoming inspection standards. The final battery solution helped the customer achieve longer lighting time, more stable smart warning performance, and smoother European market preparation. For the customer, this improved user safety, reduced battery-related design risk, and supported a more reliable smart cycling product launch.
02 – Mexico Portable Veterinary Diagnostic Reader Project
A Mexican veterinary equipment company was developing a portable diagnostic reader for animal clinics and mobile farm visits. The device needed to power a small display, sensor interface, memory board, buzzer alert, and wireless data transfer function. Since veterinarians often used the product away from charging points, the customer needed a battery that could provide stable runtime during repeated daily measurements.
The customer approached LithoTop after testing a thinner battery that saved space but could not support enough operating time for field use. They needed a rechargeable LiPo battery with higher capacity, stable voltage output, reliable protection, and a custom connector that could fit their handheld enclosure.
LithoTop analyzed the reader’s standby current, display operating time, measurement cycle, buzzer load, wireless transmission peak, charging method, internal battery cavity, and cable outlet position. Based on this evaluation, LithoTop recommended the 503450 3.7V 1000mAh LiPo battery as a compact power solution with improved runtime.
During prototype development, LithoTop optimized the PCM protection design, connector position, wire length, insulation layer, and label placement to match the customer’s assembly process. Sample batteries were tested through repeated measurement simulation, display-on runtime testing, wireless upload pulse testing, buzzer alert testing, voltage stability checking, storage testing, and installation fit evaluation.
Before pilot production, the customer confirmed approved sample performance, battery size, cable durability, connector reliability, packaging method, and inspection requirements. LithoTop then controlled production according to the confirmed golden sample and quality standards.
The final battery solution helped the veterinary diagnostic reader achieve more dependable field operation without increasing the handheld device size. For the customer, this reduced charging interruptions, improved product usability for mobile veterinary teams, and supported stronger confidence during customer trials.
