IP2369 45W 2S~6S Lithium Battery Charging & Discharging BMS Module (Supports 3S, 4S, 5S Li-ion/LiFePO4 for Drones & Power Tools)

Product Overview
This is a lithium battery charging and discharging management module with a
maximum power of 45W. It supports battery configurations from 2S to 6S and features 45W discharging capability (45W discharge requires at least a 3S battery).

• Compact Size: 45mm x 17mm.

• Core IC: Powered by the Injoinic IP2369 chip.

• Fast Charging Protocols: Integrated support for a wide range of protocols including DCP, QC2.0, QC3.0, FCP, SCP (HSCP), AFC, MTK PE, PD3.1, and PPS.

• Topology: Utilizes a built-in MOSFET buck-boost topology, enabling both step-up and step-down conversion.

• Power Handling: Supports up to 45W input and output.

Button Functionality

• Short Press (Press duration >100ms & <2s):

  • When in low-power mode, a short press wakes the module, turns on the battery level indicator LEDs, and enters no-load state. If a charging or discharging device is detected, it will automatically enter the corresponding mode.

  • In no-load state, performing two consecutive short presses within 1 second will shut down the module (entering low-power mode), turning off the LEDs and discharge output.

• No-Load Timeout: If no charging or discharging device is detected via the Type-C port for 10 seconds in no-load state, the module automatically enters low-power mode.

• System Reset: Holding the EN pin high for over 10 seconds triggers a system reset.

Key Features & Configuration

• Battery Compatibility: Supports Li-ion (3.6V-4.4V) and LiFePO4 (3.2V-3.65V) chemistries.

• Flexible Configuration via Resistors:

  • Set battery type (Li-ion/LiFePO4).

  • Set full charge voltage (3.65V, 4.1V, 4.2V, 4.35V, 4.4V).

  • Set charging power.

  • Configure number of battery cells in series (2S, 3S, 4S, 5S, 6S).

• High Efficiency: Charging efficiency up to 96%.

• Max Input Charging Power: 45W (20V @ 2.25A).

Charging Function (Input)

• Supports FCP (Huawei), AFC (Samsung), PD2.0/3.0/3.1, and PPS fast charging input protocols.

• With FCP/AFC Chargers: Requests the highest available input voltage. Constant charging current is set based on the input voltage level.

• With PD Chargers: Reads the PD capability advertisement from the adapter.

  • Requests the optimal charging voltage and sets the charging current based on the received PD information.

  • Intelligent Power Matching: If the adapter's advertised PD power is less than the module's configured charging demand, it automatically reduces the charging current to ensure input power does not exceed the adapter's capability.

Discharging Function (Output)

• Smart Type-C Interface: Integrated USB Type-C port with automatic Input/Output role detection and resistor switching.

• Automatic Role Switching: Detects whether the connected device is a source (charger) or sink (load).

• Try.SRC Functionality: When connected to a Dual-Role-Power (DRP) device (e.g., some laptops/phones), it prioritizes acting as a power source to supply power.

• Wide Output Protocol Support:

  • PD2.0/PD3.0/PD3.1

  • QC2.0/QC3.0/QC3+

  • FCP

  • AFC

  • Apple Charging

• Max Output Power: 45W.
