Customer Development Story
Discover how we helps global customers solve real-world battery challenges through customized lithium battery solutions.
01 – Australia Golf Swing Analysis Ring Project
An Australian sports technology company was developing a smart ring for golf swing analysis. The ring was designed to record hand rotation, swing speed, movement direction, and timing through a miniature inertial sensor. After each training session, the collected data could be synchronized with a smartphone application through Bluetooth.
The customer’s main challenge was internal space. The ring already contained an IMU sensor, MCU, antenna, charging contacts, and memory circuit, leaving very limited room for the battery. Their first battery option provided acceptable capacity but forced the mechanical team to increase the ring width, making it uncomfortable during club gripping.
The customer contacted LithoTop to develop a more compact rechargeable solution. LithoTop reviewed the motion sensor sampling frequency, Bluetooth synchronization load, MCU sleep current, charging method, ring cavity dimensions, and target training duration. Based on the power profile and available space, LithoTop recommended the 150732 3.8V 22mAh Smart Ring Battery.
During prototype development, LithoTop optimized insulation structure so the battery could be positioned without interfering with the motion sensor. Sample batteries were tested through continuous motion sampling, repeated Bluetooth synchronization, wake-up and sleep cycles, charging compatibility testing, voltage stability checks, and mechanical fit verification.
The customer then completed swing trials with golfers and confirmed that the smaller battery configuration allowed them to reduce ring width while maintaining the required training session runtime. Before pilot production, both teams finalized the approved sample, cable routing, charging requirements, packaging method, and inspection standards.
The final battery solution helped the customer create a more comfortable sports ring while preserving sensor performance and wireless functionality. For the customer, this improved product ergonomics, reduced mechanical redesign, and supported faster progression toward field testing and commercialization.
02 – France Finger-Worn Warehouse Scanner Project
A French logistics technology company was developing a finger-worn scanning device for warehouse picking and inventory operations. Instead of carrying a traditional handheld scanner, workers could wear the compact device on one finger and activate barcode scanning while handling cartons and products with both hands.
The device needed to power a miniature scan trigger circuit, status LED, low-power processor, memory module, and Bluetooth connection to a warehouse terminal. The customer wanted the wearable scanner to remain extremely lightweight because warehouse operators could use it continuously throughout a work shift.
Their early prototype used a battery that occupied too much space near the scanner electronics, causing poor weight distribution and making the device uncomfortable during repetitive picking tasks. The customer approached LithoTop for a smaller rechargeable battery that could support frequent wake-up events and Bluetooth transmissions without increasing the finger module size.
LithoTop analyzed the scanner activation frequency, Bluetooth transmission peak, standby current, LED operating time, charging cycle, and available battery cavity. After evaluation, LithoTop recommended the 150732 3.8V 22mAh smart ring battery as a compact rechargeable power solution.
During sample development, LithoTop adjusted the battery orientation, insulation method, and packaging structure. Sample batteries were tested through repeated scan-trigger simulation, Bluetooth communication cycles, LED status operation, standby testing, charging verification, voltage stability evaluation, and fit checks inside the finger-worn enclosure.
The customer carried out warehouse trials and confirmed that the new battery configuration improved device balance and reduced finger fatigue during repetitive work. Before production approval, both teams confirmed the golden sample, battery dimensions, packaging requirements, and batch inspection standards.
The final battery solution helped the customer maintain a compact finger-worn design while providing stable rechargeable performance for warehouse scanning functions. For the customer, this improved worker comfort, increased hands-free operation efficiency, and reduced the need for further mechanical modification.
