Feature Highlights: 1. Two-Way Current Detection – Easily monitor both charging and discharging currents without having to switch any wires. 2. Power-Off Memory – Remembers the last recorded AH and WH values after a power loss, so you can pick up right where you left off. 3. Clear Time & AH Data – Reset time and AH readings independently without interrupting ongoing measurements. 4. AH Refill Function – Allows AH to be reset to full without affecting direct discharge measurement. 5. All-in-One Display – Shows voltage, current, charge capacity (AH), energy (WH), time, and power simultaneously for a complete, easy-to-read overview. 6. Output On/Off Button – Quickly enable or disable output with a dedicated button for flexible control. 7. Full Protection – Built-in safeguards against over-voltage, over-current, and over-temperature conditions. 8. Online Calibration – Lets you adjust and correct errors in real time for accurate readings. 9. LCD Sleep Mode – Turn off the display when needed to save power and extend product life.
