Reliable, high-capacity and high-current lithium battery solutions for handheld radios, professional communication devices and industrial two-way radio systems.
LithoTop develops customized battery packs for walkie-talkies and two-way radios requiring long operating time, stable RF transmission, high pulse-current output and reliable performance in demanding field environments.
Walkie-talkies and professional two-way radios are widely used in security, construction, logistics, manufacturing, emergency services, transportation, hospitality, utilities and industrial field operations.
Modern radios may combine analog or digital communication, DMR, push-to-talk functions, GPS, Bluetooth, Wi-Fi, LCD displays, emergency alarms, encryption and high-power RF transmission.
Unlike low-power electronic devices, two-way radios may draw significantly higher current during RF transmission. Battery voltage stability directly affects transmit power, communication reliability and available working time.
LithoTop develops customized LiPo batteries, high energy density LiPo batteries, cylindrical Li-ion battery packs, high-rate battery options and low-temperature battery solutions for handheld radio manufacturers.
Custom battery solutions for professional communication, industrial operations, emergency response and portable radio systems.

Battery selection depends on radio dimensions, RF transmission current, working time, weight, charging method and operating environment.
Providing complete electrical, mechanical and charging information helps LithoTop evaluate a suitable walkie-talkie battery solution.

* Custom Lipo Battery from LithoTop Now !
Send us your available battery dimensions, required voltage, capacity, receive current, transmit current, RF power, duty cycle, charging dock design and operating temperature. LithoTop will evaluate a suitable walkie-talkie battery solution for your project.
Most modern walkie-talkies use rechargeable Li-ion or LiPo battery packs. 14500, 18650 and custom pouch-cell configurations can be selected according to radio size, voltage, capacity and discharge-current requirements.
Battery capacity should be selected according to standby current, receive current, transmit current, RF output power, transmit / receive duty cycle and required working time.
RF transmission requires significantly more current than standby or receive mode. A battery with suitable high-current capability helps maintain stable voltage and reliable radio transmission during high-power transmit events.
Yes. LithoTop can customize 2S Li-ion or LiPo battery packs with different capacities, housings, charging contacts, NTC terminals, wire configurations and protection circuits.
Yes. Battery cells, PCM or BMS, plastic housings, charging contacts and mechanical locking structures can be customized according to the radio design and installation requirements.
Yes. LithoTop can customize charging contacts, NTC terminals, communication pins and mechanical positioning according to the charging cradle or docking station design.
Yes. LithoTop can evaluate low-temperature battery solutions for winter construction, outdoor security, mountain operations and other cold-environment communication applications. The required temperature, RF load and runtime should be confirmed during battery selection.
Yes. Higher-capacity Li-ion or LiPo battery packs can be developed according to available installation space, maximum battery weight, radio power demand and required operating time.
Please provide the required nominal voltage, capacity or target runtime, maximum battery dimensions, continuous current, peak transmit current, RF duty cycle, charging method, connector or charging-contact design, operating temperature and estimated quantity. Radio drawings, existing battery samples and certification requirements are also helpful for engineering review.
