Product features:
1. The module is suitable for 3.7V lithium batteries, including polymer, 18650, 21700 and other lithium batteries;
2. With digital display, high efficiency, complete protocols, mainstream open protocols are basically supported;
3. Upgrade high-power mobile power motherboard, small size, high power, power low ripple, material enough, protocol full, compatible with good;
4. Product design, materials, PCB process with enough effort, so that the module can be done in a very small volume above the very impressive parameters and features;
5. Module size is relatively small, the heat dissipation area is limited, high-power output heat is a normal phenomenon, we use good materials, do not have to worry about the impact of heat life.

For example, the common cell phone Huawei, Apple, OPPO, glory, millet, real me realme, a plus, Samsung, Nubia and other brands, most models support fast charging. In addition, VIVO/IQO0 cell phones can also be fast-charged if they support the 9V/2A protocol.
Product size: 71.5mm * 18mm * 8.5mm

Module input interface:
Buttons: short press action, open the USB port as well as the lightly loaded Type-C output port for external discharge and power display. When double-click action, close the USB port and Type-C output port and power display; if there is an external power supply present, only the output port will be closed.
Type-C port: support input and output.
USB port: high current output interface.
B+: battery positive interface, use must be welded, the wire must be thick, not too long.
B-: battery negative interface, use must be welded, the wire must be thick and not too long.

Precautions for use
◆ motherboard received, first connected to the charging head test, see the LED light status, confirm that the lights are bright and then assembled. If you do not test the LED lights directly connected to the battery, resulting in the LED lights do not light, do not say that our board quality problems, the board will be tested after the factory.
◆ Normal application, the battery must be welded, (wire twisting will be insufficient power supply), the battery reverse. Connect the motherboard must burn. Never pay attention. The line is as thick and short as possible.
◆ Battery and motherboard line can not be too thin, try to be thicker. Fast charging board requires 10A current, non-fast charging board should also be able to pass 7A current. The interface needs to be welded.
◆ Batteries can only be connected in parallel (unlimited number of parallel connections), not in series, series connection must burn the motherboard.
◆Make sure the battery is good, if connected. ◆ Make sure the battery is good, if the battery is connected to a full charge, plug the phone can not be discharged, most of the battery aging scrapped.
◆ If the battery comes with a protection board, make sure that the protection board protection current is greater than 7A (fast charging version of the requirements of more than 10A), otherwise remove the protection board, otherwise it may be discharged beyond the one or two amps on the protection of the disconnected output.
◆ The board will be burned if it is connected inversely. There will be traces of burnt IC. Only reverse connection will appear this situation. Therefore, this side will not bear the consequences of reverse connection. For example, the protection chip burned or burned off, the main control chip burned out obvious traces of the protection chip burned out 100% is the use of the problem, when please do not pull the skin.
◆ Access to the battery to determine access to the 3.7V lithium batteries, not other batteries. Ensure that the battery is not connected in series, otherwise the battery terminal access voltage is higher than 4.5V may burn the board.
◆ Where the power supply will heat, this is electronic common sense, everyone's products are the same, if not heat, the current will not only be limited to 5A, do a 10A, 100A is not very cattle? Board cost and volume size here, the module uses a large factory mainstream chip, efficiency performance is good, rest assured that the use.
◆ Board power indicator built-in coulomb meter, just connected to the battery display will not be allowed, the power meter to support the battery capacity self-learning function, more than a few times the complete charging process can learn the current battery capacity. ◆ When the use of problems encountered, contact customer service must cooperate with customer service to provide wiring pictures, use video, etc., do not accept only provide text information.
