Features:

1. Use of high-quality materials, product quality is guaranteed

2. Small volume, high power, high efficiency, complete protocols, mainstream open protocols are basically supported

3.Module for 3.7V lithium batteries, including polymer, 18650, 21700 lithium batteries; to ensure that the battery is not aging, the battery can be connected in parallel can not be connected in series

4. Module volume is relatively small, the heat dissipation area is limited, high-power output heat is a normal phenomenon

5. Wide range of product applications, suitable for a variety of industrial DIY occasions

Support FCP, SCP, HSCP
Support SFCP to charge battery
Support PD3.0/PD2.0, AFCFCP, SCP , PE1.1

using:
1. Battery and motherboard cable can not be too thin, try to be thicker. Fast charging board requirements can pass 10A current non-fast charging board should also be able to pass 7A current. Can not be too long, the interface needs to be welded.
2. Batteries can only be connected in parallel (parallel number is not limited), not in series, series must burn the motherboard.
3. Normal application, the battery must be welded, (wire twisting will be insufficient power supply), the battery reverse motherboard must burn. Never pay attention. Line as thick and short.
4. Access to the battery to determine access to the 3.7V battery, not other batteries. Ensure that the battery is not connected in series, otherwise the battery terminal access voltage higher than 4.5V may burn the board.
