Customer Development Story

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

01 – Smart Wellness Wearable Project from Denmark

A Danish wearable electronics company was developing a compact wellness device for daily activity tracking and gentle vibration reminders. The product needed to support Bluetooth connection, motion sensing, LED indication, and standby operation while remaining lightweight and comfortable for users.

The customer contacted LithoTop because their previous standard 3.7V battery could fit the product structure, but the runtime was not strong enough during real usage simulation. Increasing battery size would have affected the product thickness and wearing comfort, so the customer needed a higher energy density solution.

LithoTop reviewed the wearable device layout, standby current, Bluetooth transmission peak, vibration motor load, charging circuit, cable routing, and target runtime. After evaluation, LithoTop recommended the 422424 3.85V 260mAh High Voltage Polymer Battery. Our engineering team judged that the 3.85V high-voltage platform could provide more usable energy within a compact battery size, while the 260mAh capacity matched the customer’s lightweight design goal.

During sample development, LithoTop optimized the connector type, wire length, PCM protection option, cable outlet direction, and battery label to match the customer’s assembly process. Sample testing included capacity verification, Bluetooth transmission simulation, vibration load 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 wearable product achieve more stable daily runtime without increasing product size. For the customer, this improved user comfort, reduced redesign pressure, and supported a smoother product launch.

02 – Smart Asset Tracker Project from Canada

A Canadian IoT company was developing a compact smart asset tracker for tools, luggage, and portable equipment. The device required stable power for Bluetooth communication, motion detection, buzzer alerts, and periodic status updates. Their previous small battery worked during standby testing, but voltage dropped quickly when the wireless module and alert function operated at the same time.

The customer approached LithoTop because they needed a custom battery manufacturer that could evaluate real operating conditions instead of only supplying a standard battery model. LithoTop analyzed the tracker’s standby current, wireless transmission interval, buzzer load, charging method, enclosure space, and expected daily usage cycle.

Based on the analysis, LithoTop recommended the 422424 3.85V 260mAh high voltage polymer battery. The 260mAh capacity helped keep the tracker small and lightweight, while the high-voltage chemistry provided better usable energy than a standard 3.7V battery of similar size.

During prototype development, LithoTop adjusted the PCM protection design, connector position, wire length, insulation method, and packaging requirement to match the customer’s assembly process. Sample batteries were tested through standby simulation, wireless pulse testing, buzzer load testing, voltage stability checking, charge-discharge cycling, storage testing, and installation fit evaluation.

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

The final battery solution helped the smart tracker maintain stable operation during alerts and wireless updates. For the customer, this reduced unexpected shutdowns, improved field reliability, and made the product more competitive in the compact IoT tracking market.

Why Choose LithoTop for 422424 High Voltage Polymer Battery Solutions?

Factory Support

High voltage polymer 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.
