Vapcell BL4 universal charger with 4 slots for Li-ion, LiFePO4, NiMH, and 1.5V Li-ion batteries

Vapcell BL4 – Universal 4-Slot Smart Charger

The Vapcell BL4 is a high-performance, professional-grade charger designed not only for charging but also for analyzing, repairing, and safely preparing batteries for long-term storage. Combining modern technology (USB-C), intuitive operation, and a high level of safety, this device is perfect for both daily use and technical hobbyists.

Key Features & Benefits:

• 4 Independent Charging Channels: Each slot operates individually, allowing you to charge batteries of different capacities, chemistries, or sizes simultaneously.

• 5 Operating Modes:

  • Charge: Standard fast charging.

  • Test: Charge -> Discharge (capacity measurement) -> Charge. Accurately determines real battery capacity (mAh).

  • Storage: Automatically charges or discharges Li-ion batteries to the optimal storage voltage (approx. 3.7V–3.8V), ensuring longevity.

  • Discharge: Full battery discharge.

  • Repair: A special algorithm to reactivate deeply discharged (potentially damaged) batteries.

• Dual Operation Modes:

  • Simple: Automatic parameter selection – just insert the battery.

  • Pro: Manual adjustment of current (50 mA to 3000 mA), voltage, and mode settings.

• Smart LCD Display: Real-time data including voltage (V), charging current (A), accumulated capacity (mAh/Wh), internal resistance (mΩ), and time. Display orientation can be rotated.

• Powerbank Function: Built-in USB output allows you to use the charger as a power source for external devices (phones, etc.) when loaded with charged Li-ion batteries.

• High Safety Standards: Protection against short-circuit, overheating, reverse polarity, and overcharging.

Technical Specifications:

• Input: QC3.0 / USB-C (5V/3A – 9V/2A).
