Cautions

  1. Ensure the battery is properly connected.
  2. Do not reverse the output connection to avoid burning the chip.
  3. Use adequately thick and short wires for connections.
  4. Only connect the current meter in series with the 5V input.
  5. Recommended charging current is about 37% of battery capacity (e.g., 400mA for 1000mAh battery).
  6. High voltage protection: If input voltage exceeds 5V, charging current is automatically reduced to protect the chip.
