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.
