Description
🔹 Key Features
Precise Custom Calibration：You can freely set the full-charge voltage (100%) and empty voltage (0%) according to your battery type, ensuring the displayed battery level is 100% accurate.
Smart Low Voltage Protection：When the battery level drops below the set threshold, the red lightning symbol on the screen will flash to alert you, preventing battery damage caused by over-discharge and extending battery life.
Adjustable Backlight Design：The LED backlight supports always-on or timed-off mode, you can adjust the brightness and time according to your usage scenario, ensuring clear visibility day and night.
Power-off Memory Function：Even in case of accidental power cut, the device will automatically save the current battery level data, no need to re-calibrate after restart, very convenient for daily use.
Ultra-Wide Battery Compatibility：Supports multiple battery types: 3S-12S ternary lithium batteries, 3S-14S LiFePO4 batteries, 12V/24V/36V/48V lead-acid batteries, perfect for electric vehicles, energy storage systems, DIY projects and industrial applications.
