IP2326 USB Type-C 2S/3S Lithium Battery Charging Module 15W

The IP2326 USB Type-C Lithium Battery Charging Module is a compact boost-charging circuit designed for rechargeable lithium-ion battery packs containing two or three cells connected in series. It supports selectable 2S and 3S configurations, providing charging voltages of 8.4V and 12.6V respectively for compatible battery packs. The USB Type-C input offers a convenient charging interface, with fast-charging support depending on the connected power adapter and module version.

Built around the IP2326 charging controller, the module uses a synchronous boost-conversion circuit to increase the input voltage to the level required by the battery pack. Its rated charging power is up to 15W, with a maximum charging current of approximately 1.5A, depending on the selected configuration and operating conditions. The charging current and cutoff voltage may be adjustable through onboard resistor or solder-pad settings, depending on the board revision.

The module also supports cell balancing in the supported configuration. For 2S battery packs, the balancing circuit helps reduce voltage differences between the two series-connected cell groups during charging. Balancing support and performance should be checked for the selected configuration, as it may differ between 2S and 3S operation.

The IP2326 module is suitable for DIY rechargeable battery systems, portable electronics, robotics, and other embedded projects requiring a compact charging solution. It may include charging-status LEDs and provisions for an external temperature sensor, depending on the version. It is a charging module and should not automatically be treated as a complete replacement for a battery protection board.

For reliable operation, use matched lithium-ion cells, configure the module for the correct number of series cells, and follow the wiring diagram supplied with the board. A compatible USB power source is required, and the available charging power depends on its voltage, current capability, and fast-charging protocol support.
