Multi-function Large-screen Battery Monitor
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.
Comprehensive Battery Information Monitoring
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.
Durable Long-life Design for Prolonged Use
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.
User-friendly Features for Safety and Convenience
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.

FAQ:
(1) What is the purpose of a battery monitor?
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.
(2) What types of battery packs can the battery monitor be used
for?
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.
(3) What is the after-sales service like?
We provide a one-year warranty period. After one year, if the
product is damaged due to its own quality issues, we will continue
to offer repair or replacement services based on the specific
circumstances. For cases where returns or exchanges are not
possible due to reasons such as shipping costs, replacements will
be sent with the next order.
