Frequently Asked Questions (FAQs)

• Q: What type of batteries can I charge with this module?
  A: This module is designed for 4-cell (4S) series-connected lithium-ion batteries, such as 18650, 21700, and similar cells, totaling a nominal voltage suitable for 16.8V charging.
• Q: What is the recommended input power source for the Type-C port?
  A: A 5V USB power source is recommended for optimal performance. While it supports 3V-6V, 5V ensures stable operation.
• Q: Can I use this for a 3S or 5S battery pack?
  A: No, this module is specifically designed for 4S configurations (4 cells in series) and will not function correctly or safely with other configurations.
• Q: What does the "Quasi-CV" mode mean?
  A: Quasi-Constant Voltage mode is an advanced charging technique that balances efficiency and battery health by slightly adjusting the voltage curve towards the end of the charging cycle.
• Q: How do I know if my battery pack is compatible?
  A: Ensure your battery pack consists of 4 lithium-ion cells connected in series, with a nominal voltage that sums up to a configuration suitable for 16.8V charging (e.g., four 3.7V nominal cells). Always check your battery manufacturer's specifications.
