Frequently Asked Questions

• How do I configure the module for my battery pack?
  The module features solder pads on the PCB (labeled 2S, 3S, 4S) for selecting your battery series configuration, and another set of pads (labeled 1A, 2A, 4A) for setting the desired charging current. You will need to bridge the appropriate pads with solder to match your battery requirements.
• What type of power supply is required for this charger?
  You can power the module via its USB-C port with a DC 3-6V source, such as a standard 5V USB adapter. For the 4A charging option, ensure your power supply can provide at least 4A of current. Alternatively, you can directly wire a DC 3-6V supply to the VIN/GND pads on the board.
• Is this charger suitable for all types of Lithium batteries?
  This module is specifically designed for Lithium-ion (Li-ion) battery packs in 2S, 3S, and 4S configurations, with specific charging voltages of 8.4V, 12.6V, and 16.8V. While many LiPo batteries share similar voltage characteristics, always verify compatibility with your specific battery’s manufacturer specifications before use.
