The TF03K is designed for medium/large-sized battery packs, serving as a large-screen battery monitor. Through highly integrated information display and robust industrial design, it provides users with an accurate and intuitive energy management experience.
Equipped with a 2.8-inch large screen, the TF03K simultaneously displays six key parameters: voltage, current, power, capacity, state of charge (SOC), and estimated remaining usage time. Users can quickly assess battery status—such as verifying load conditions through voltage/current readings—and plan workflows or charging schedules based on SOC and remaining time. For manufacturers, integrating this display enhances product professionalism and fulfills user demands for data visibility and precise battery management.
Featuring embedded installation and front-panel protection, the TF03K seamlessly integrates into battery cases or equipment panels, resisting dust, water splashes, and vibration. Its ultra-low power consumption (12mA during operation, 2mA in standby) has negligible impact on the battery pack, ensuring no capacity drain during long-term storage. This is critical for batteries requiring extended standby periods, directly boosting product reliability and long-term stability.
The TF03K supports multi-level screen brightness adjustment, ensuring clear visibility in both daylight and low-light environments. Additionally, its customizable low-capacity alarm triggers a buzzer when capacity falls below a set threshold, reminding users to recharge promptly. This prevents over-discharge damage, extending overall battery lifespan.

Battery monitors can be used in any scenario involving battery packs. They continuously track the status of the battery pack and display key parameters such as remaining charge, current voltage, current, power, and other relevant data. This allows users to monitor battery health in real time, helping to protect the battery and extend its lifespan.
It is compatible with mainstream battery types on the market, such as lead-acid batteries, lithium-ion batteries, lithium iron phosphate batteries, sodium batteries, etc.
