Customer Development Story
Discover how we helps global customers solve real-world battery challenges through customized lithium battery solutions.
01 – Hungary Museum Audio Guide Project
A Hungarian cultural technology company was developing a rechargeable audio guide for museums, historic sites, and exhibition centers. The device needed to power an audio decoder, small display, headphone amplifier, RFID trigger module, control buttons, and wireless content update function. Because visitors often used the audio guide for several hours, the customer needed stable runtime without making the handheld device too thick or heavy.
The customer contacted LithoTop after evaluating several cylindrical cells that either provided insufficient voltage or occupied too much space inside the narrow enclosure. Their electronics were designed around a 7.4V input platform, so they needed a compact 2S rechargeable battery with a slim cylindrical structure.
LithoTop reviewed the audio guide’s playback current, display usage, RFID activation cycle, wireless update load, charging circuit, battery compartment dimensions, and expected daily visitor usage. After evaluation, LithoTop recommended the 14650 2S 7.4V 1100mAh Li-ion Battery. The 14650 cell diameter matched the available internal space better than a larger cylindrical format, while the 2S structure provided the required operating voltage.
During sample development, LithoTop optimized the PCM protection design, cable length, connector orientation, insulation sleeve, and battery arrangement. Sample batteries were tested through continuous audio playback, display operation, RFID activation, wireless update simulation, charging compatibility verification, and enclosure fit checking.
Before production approval, both teams confirmed the sample, battery dimensions, connector orientation, charging requirements, PCM parameters, packaging method, and incoming inspection standards. The final battery solution helped the audio guide achieve reliable daily operation while maintaining a compact handheld design. For the customer, this reduced charging interruptions and improved visitor equipment management during busy exhibition periods.
02 – Argentina Portable Soil Salinity Meter Project
An Argentine agricultural instrumentation company was developing a portable soil salinity meter for vineyards, irrigation projects, and crop management. The device needed to power a measurement probe interface, digital display, data memory, buzzer, and short-range wireless communication module. Field technicians often used the meter across large agricultural areas, so the battery needed to provide stable output throughout repeated measurement cycles.
The customer’s first prototype used a larger battery pack that provided sufficient runtime but made the meter handle bulky and uncomfortable during long field surveys. They wanted a narrower cylindrical battery solution that could still provide the 7.4V required by the measurement electronics.
LithoTop analyzed the meter’s measurement current, display operating time, data logging frequency, wireless transmission peak, charging circuit, handle dimensions, cable routing, and daily field usage pattern. Based on this evaluation, LithoTop recommended the 14650 2S 7.4V 1100mAh Li-ion battery as a more compact power solution.
During prototype development, LithoTop adjusted the pack arrangement, PCM layout, connector position, wire length, insulation structure, and outer sleeve to fit the meter handle. Sample batteries were tested through repeated measurement cycles, display runtime testing, wireless data transmission, voltage stability evaluation, charging verification, vibration handling checks, and mechanical fit testing.
The customer then conducted field trials across irrigation zones and confirmed that the battery provided sufficient working time while reducing the overall handle size. Before pilot production, both teams finalized the approved battery sample, cable configuration, connector durability, labeling, packaging, and quality inspection requirements.
The final battery solution helped the customer develop a lighter and more ergonomic soil measurement instrument without changing the 7.4V system architecture. For the customer, this improved technician comfort, simplified field operation, and reduced mechanical redesign work.
