The TX20 features a high-contrast black-and-white segment screen that remains clearly readable even in sunlight, making it ideal for the variable lighting conditions in RVs. The screen can simultaneously display three critical battery parameters—such as voltage, current, and remaining capacity percentage—allowing you to grasp the RV battery status instantly. Without toggling through complex menus, a quick glance while driving or parked is enough to access key information, effectively avoiding power depletion issues or unexpected shutdowns for a worry-free RV experience.

Energy efficiency and battery endurance are crucial for RV trip planning. The TX20 adopts an ultra-low power design, consuming only 25mW in standby mode and 250mW at 50% brightness, barely draining the battery and efficiently preserving your RV’s energy. The built-in light sensor automatically adjusts screen brightness—enhancing readability during the day and dimming at night—saving power without disturbing rest, ultimately extending off-grid parking time.

Via Bluetooth connection to a mobile app, you can access all detailed battery parameters and historical data without approaching the display—managing your battery as easily as checking a phone notification. Additionally, the surface-mount casing (optional) is tailored for easy RV installation, requiring no complex panel cutouts for quick setup, enabling a seamless upgrade to your RV’s battery management system.

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.
