Frequently Asked Questions
Q: What type of battery is this IP2312 charging board compatible with?
A: This charging board is designed specifically for single-cell 3.7V polymer ternary lithium batteries (Li-Po / Li-ion). It charges to a cut-off voltage of 4.2V using CC/CV mode, which is the standard safe charging profile for these battery types.
Q: Can I adjust the charging current on this board?
A: Yes. The charging current is set at 3A by default but can be adjusted by modifying the onboard sense resistor. Lower currents (1A, 2A) also yield higher conversion efficiency (up to 95%), making it flexible for various battery capacities and project requirements.
Q: What do the LED indicator lights mean?
A: The board features two LED status indicators: a Red LED that illuminates while the battery is actively charging, and a Blue LED that lights up when the battery is fully charged and the charging process is complete.
Q: What input is required to power this charging module?
A: The module accepts input via a USB Type-C connector with an operating voltage range of 4.5V to 5.5V (standard 5V USB). A USB charger or power supply capable of delivering at least 3A output is recommended for maximum charging speed.
