Customer Development Story

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

01 – Portable Translator Project from Japan

A Japanese consumer electronics company was developing a compact portable translator for business travel and education users. The device required stable power for a display, microphone, speaker, wireless communication module, and real-time translation processor. Their previous battery met the size requirement, but the runtime was not long enough for full-day travel use.

The customer contacted LithoTop because they needed a higher energy density battery solution without redesigning the product housing. LithoTop reviewed the translator’s standby current, audio playback load, wireless transmission peak, charging circuit, enclosure space, and target operating time.

After evaluation, LithoTop recommended the 702229 3.8V 630mAh High Voltage LiPo Battery. Our engineering team judged that the 3.8V high-voltage platform could provide more usable energy than a standard 3.7V battery, while the 630mAh capacity offered a strong balance between runtime and compact product design.

During sample development, LithoTop optimized the connector type, wire length, cable outlet direction, PCM protection option, and battery label to match the customer’s assembly process. Sample testing included capacity verification, audio operation simulation, wireless transmission testing, charging compatibility checking, temperature monitoring, and installation fit verification.

Before mass production, both teams confirmed samples, battery dimensions, connector specifications, charging requirements, labeling details, and batch inspection standards. The final battery solution helped the translator achieve longer working time and more stable power behavior during real use. For the customer, this improved user experience, reduced redesign pressure, and supported a smoother product launch.

02 – Smart Wearable Audio Device Project from Spain

A Spanish wearable electronics company was developing a smart wearable audio device for sports and outdoor users. The product needed to support Bluetooth connection, audio playback, voice interaction, and standby operation while remaining lightweight and comfortable to wear. Their previous standard LiPo battery caused runtime limitations during continuous audio testing.

The customer approached LithoTop because they needed a compact high voltage LiPo battery that could improve runtime without making the wearable product thicker or heavier. LithoTop analyzed the device’s Bluetooth current profile, speaker load, voice wake-up frequency, charging method, battery compartment tolerance, and cable routing requirement.

Based on this analysis, LithoTop recommended the 702229 3.8V 630mAh high voltage LiPo battery. The 630mAh capacity supported longer audio operation, while the 3.8V high-voltage chemistry helped improve available energy inside the limited space. LithoTop also suggested optimizing the cable outlet direction to simplify assembly and reduce wire bending stress.

During prototype development, sample batteries were tested through continuous Bluetooth playback, voice activation simulation, voltage stability checking, charge-discharge cycling, storage testing, and installation fit evaluation. The customer confirmed that the battery provided more stable runtime during real usage simulation.

Before mass production, the customer approved the final sample, connector durability, electrical performance, packaging method, and incoming inspection standard. LithoTop then controlled production according to the confirmed golden sample.

The final battery solution helped the wearable audio device achieve longer use time and fewer low-power interruptions. For the customer, this improved product reliability, strengthened user satisfaction, and made the device more competitive in the smart wearable market.

Why Choose LithoTop for High Voltage LiPo Battery Solutions?

Factory Support

High voltage LiPo batteries require more than a higher nominal voltage. To achieve reliable performance, the battery must control material stability, voltage consistency, internal resistance, thickness tolerance, cycle performance, charging compatibility, and protection circuit design.

LithoTop supports customers from sample development to mass production with professional engineering support and strict quality inspection. Our team can help evaluate battery size, runtime target, charging voltage, working current, connector type, PCM design, NTC requirement, and real application conditions before confirming the final battery solution.
