Clear Display with Core Parameters on a Single Screen
The TX21 features a classic black-and-white segment screen with an
intuitive interface, displaying three key battery parameters (e.g.,
voltage, current, capacity) simultaneously on one page. Users can
quickly access essential information without frequent page
switching. The device supports flexible toggling between six
battery parameters (voltage, current, remaining capacity, total
capacity, power, and estimated runtime), enabling targeted
monitoring of critical data for clear and immediate status
overview.
Ultra-Low Power Consumption with High-Precision Monitoring
Designed with an ultra-low power consumption architecture and paired with a high-precision shunt, the TX21 minimizes operational energy draw, ensuring negligible
impact on battery life during long-term use. Core parameters like
voltage and current are monitored with an accuracy of ±1.0%, providing reliable data for precise battery status assessment.
Smart Light Sensing and Bluetooth App Connectivity
Equipped with built-in Bluetooth, the TX21 pairs with a dedicated mobile app for convenient battery
data viewing and management on smartphones. The integrated ambient light sensor automatically adjusts screen brightness based on environmental
conditions—ensuring clarity in bright light and reducing glare in
dim settings—enhancing usability across diverse scenarios.
Flexible Installation for Diverse Needs
An optional surface-mount casing simplifies installation, requiring no complex panel modifications.
This design adapts to various practical applications while
minimizing deployment complexity.

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.
