The TX21 utilizes a high-contrast black-and-white segmented screen, ensuring clear readability in both bright and low-light conditions. The screen simultaneously displays three core parameters—voltage, current, and remaining battery capacity—enabling RV users to monitor battery status in real time. With button-controlled navigation, users can toggle through six key data points, including power, total capacity, and estimated remaining runtime, fully addressing battery management needs during travels.
Designed for extended off-grid RV use, the TX21 operates at minimal power consumption, with standby power as low as 25mW, avoiding unnecessary drain on the vehicle’s battery. Coupled with high-precision sampling technology, it delivers highly reliable data with a typical accuracy of ±1.0%, empowering users to make informed energy decisions and prevent unexpected power failures.
With Bluetooth support, the TX21 pairs with a dedicated mobile app, allowing users to review historical data and adjust device settings remotely. The built-in ambient light sensor automatically adapts screen brightness—reducing glare at night while maintaining clarity during the day—for an optimized round-the-clock user experience.
The TX21 offers an optional surface-mount casing, enabling tool-free installation without panel cutouts, ideal for retrofits and DIY enthusiasts. Whether wall-mounted or panel-embedded, it easily integrates into various RV interiors, bringing intelligent power management to life quickly and effortlessly.

The photograph above presents a genuine electronics manufacturing facility in which battery monitoring and information collection products such as the TX21 are built. The workshop contains well-organised production stations, storage areas for components and materials, assembly equipment, production tooling, and work-in-process items.
For the TX21 and similar products, manufacturing and inspection work is carried out in line with the approved product specifications, production requirements, and applicable quality-control procedures. Depending on the particular configuration, the relevant operations may cover electronic component handling, assembly, wiring or connection, functional verification, and other production and inspection steps.
The orderly production layout and dedicated workstations offer a suitable setting for electronics manufacturing and quality-control activity. This factory photograph serves as first-hand visual evidence of the manufacturing environment behind the TX21, helping customers understand where and how the product is made.
The exact production, assembly, and inspection procedures may differ according to the confirmed TX21 configuration, approved specifications, and applicable production requirements.
The TX21 RV battery management system is intended for embedded panel mounting and is secured by a side-mounted C-shaped retaining clip. With this arrangement, the unit is introduced through the front of the equipment panel and locked in place from behind once the necessary panel cut-out has been prepared.
Installation Steps
Step 1: Prepare the Panel Cut-out
Cut a rectangular opening in the equipment panel in accordance with the TX21 cut-out dimensions specified in the installation drawing.
Step 2: Fit the Unit into the Panel
Slide the TX21 unit into the prepared opening from the front of the panel, orienting it so that the grooves on both sides remain accessible for the retaining clips.
Step 3: Lock the Unit with the C-Shaped Clips
Place the C-shaped retaining clips into the side grooves of the TX21, pass the screws through the clip holes, and tighten them gradually so that the unit is held firmly against the panel.
Installation Note
Prior to mounting, confirm the TX21 cut-out dimensions, panel thickness, mounting orientation, and fastening method against the approved product drawing and configuration. Tighten the retaining screws evenly, taking care not to apply excessive force to the housing or the panel.
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.
