9: Applications: High-power charging for multi-cell lithium batteries, power bank modifications, solar charging.

10: Multi-specification:

2-cell full charge: 8.4V

3-cell full charge: 12.6V

4-cell full charge: 16.8V

Usage Method:

The module input supports either a Type-C interface or direct soldered wiring. The input voltage ranges from 4.5V to 15V. Depending on the settings of resistors R1 and R2, the battery can be configured with 1 to 4 series of lithium batteries or lithium iron phosphate batteries. The battery must have a protection board; one with automatic voltage balancing is preferable. If fast charging is used for the input, two series can be set to a 9V input, and three or more series can be set to a 12V input. Of course, no setting is also possible.

Additional Charging Voltage Configuration Notes

Given the module's broad charging range, only common configurations are provided. For custom setups, adjust R1 and R2 resistors accordingly. The charging cutoff voltage can be calculated using the formula below.

Model 2: Blackboard Version:

1. Multi-cell (unlimited parallel connections) 3.7V lithium battery charger (single cell full charge 4.2V)

2. 4.5-21V wide input voltage range

3. Supports PD and QC fast charging

4. Power output adjusts based on input voltage: 18W at 12V, 25W at 20V. Current calculated proportionally to voltage

5. Features charging status, full charge, and fast charge indicators

6. Built-in over-temperature and short-circuit protection

7. Three-stage charging: trickle/constant current/constant voltage.

8. Designed for wide input voltage and multi-cell battery output. Operates normally with protection board. Features indicator lights: full charge indicator illuminates when fully charged. If protection board triggers early shutdown, flashing full charge indicator is normal.

9. Recommended voltage: 4.8-20V

B-: Battery negative terminal (protection board P-)

B+: Battery positive terminal (protection board P+)

9/12/20 Shorting Point: Sets the trickle voltage; unshorting defaults to 5V.

Precautions:

* Never reverse battery polarity; reverse connection will burn the board.

* Connect the charger before attaching batteries to verify the charging indicator functions correctly.

* Use sufficiently thick wiring to handle charging currents; all connections must be soldered.

* Batteries must include a protection board.

*Heat dissipation is critical during high-power operation. Avoid enclosing the module in heat-insulating materials.

FAQ:

1. Which fast-charging protocols does this product support?

Answer: Currently supports the widely adopted QC protocol, compatible with most fast-charging power adapters on the market.

2. Does the module generate significant heat?

Answer: Heat output varies with charging power. Higher power levels result in greater heat generation, which is normal.
