The TF03K is a high-performance multifunctional battery monitor designed for precise monitoring of battery status. It features a large 2.8-inch display that simultaneously shows six key parameters: voltage, current, power, capacity, SOC, and remaining usable time. With no need for complicated switching, users can easily keep track of their battery’s performance, making it an ideal solution for managing energy in RVs, energy storage systems, engineering vehicles, and more.
While delivering powerful functionality, the TF03K also prioritizes energy efficiency and user experience. Users can manually adjust screen brightness for optimal visibility. When the battery is idle—neither charging nor discharging—the device automatically enters a low-power standby mode and turns off the backlight, reducing power consumption from an already low 12mA to just 2mA. Additionally, the configurable low-capacity alarm reminds users to recharge in time, effectively preventing over-discharge and extending battery life.
The TF03K supports a wide voltage range of 8V to 120V and a current range of 0A to 750A, making it compatible with common lead-acid batteries and various lithium batteries (such as ternary lithium and lithium iron phosphate) as well as sodium-ion batteries. Its adaptability allows for easy application across various fields—from monitoring RV and energy storage system batteries to displaying battery status in engineering vehicles like forklifts—providing reliable data support in all scenarios.
Through long-term use in RVs, energy storage systems, engineering vehicles, and other applications, the TF03K has proven its reliability and practicality in the market. To meet diverse integration needs, professional OEM/ODM customization services are available, covering aspects such as product appearance and factory parameter configuration.

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.
