15W 3A High-power UPS18650 Lithium Battery Boost Charging Module (9V)
- Notes:
- There are MOS and other components on the board, which are easily damaged by soldering iron induction electricity or static electricity. Please make sure that the soldering iron used is grounded (and the ground wire of the power strip is connected). It is best to wear anti-static gloves when operating.
- Be careful not to install the battery upside down, otherwise the board may burn.
- Please choose a power supply with sufficient power. Only in this way can the board work properly.
- The board power supply should not be higher than 5V.
- Please do not modify the board without technical confirmation.
- It is normal for the module to heat up when working at high power, just pay attention to fanning.
