    C4 EVO Smart AA AAA 18650 Battery Charger Tester for Ni-MH/Zn Li-Ion | Fast Rechargeable Battery Discharger Analyzer with LCD Display USB-C Input Activate Cycle, 1.5V Battery Charger

    • [More Than a Battery Charger] The C4EVO universal battery charger combines smart charging, battery testing, analysis and maintenance in one device. Designed for users who want to monitor battery condition, measure performance and manage rechargeable batteries beyond basic charging.
    • [Six Independent Charging Channels] Each slot operates independently, allowing different battery types and different working modes to run at the same time. Charge one battery while analysing, cycling, discharging or storing another.
    • [Advanced Battery Management Modes] Supports Charge, Discharge, Storage, Cycle, Analyze and Activate modes for compatible NiMH, NiZn, Li-Ion, LiFe and LiHV batteries. Available functions depend on the selected battery chemistry.
    • [Wide Compatibility with Clear Mode Limits] The rechargeable battery charger works with most household batteries, supports NiMH, NiZn, 3.6/3.7V Li-Ion, LiFe, LiHV and 1.5V Li-Ion, AAA AA and all sizes ranging from 10440 to 26700. 1.5V Li-Ion batteries support charging only and do not support Discharge, Storage, Cycle, Analyze or Activate modes. (Note: Ni-Zn/LiHV batteries require manual battery type selection.)
    • [Real-Time Monitoring & USB-C Fast Input] The 2.4-inch LCD displays battery type, voltage, current, capacity, charging time, internal resistance, temperature and working curves. C4 EVO high speed charger use an 18W or higher QC/PD USB-C adapter for stable operation.

    FAQ

    Q: Why does the charger restart or flash during charging?

    A: The C4EVO requires a fast-charging USB-C adapter (PD/QC) with at least 18W output. Low-power adapters may cause restarting, flashing, or unstable charging.

    Q: Why does the battery get warm during charging?

    A: The default current is up to 1.5A for faster charging, which may cause warmth. For lower heat and longer battery life, we recommend reducing it to around 0.6A.

    Q: How do I charge 1.5V Li-ion batteries?

    A: Update C4EVO to firmware V2.0.0.1 or later using Windows only. Then manually select “1.5V Li-Ion” mode—not the standard “Li-Ion” mode—before charging.

    Q: Can C4EVO discharge or analyze 1.5V Li-ion batteries?

    A: No. For 1.5V rechargeable Li-ion batteries, C4EVO supports charging only. Discharge, Analysis, Cycle, and other maintenance modes are not available.

    Q: What is Destroy mode used for?

    A: Destroy mode safely discharges batteries before disposal. It is designed for damaged or unwanted batteries and is not intended for normal daily use.
