7. Precautions for use:
1) When connecting the battery lead, note not to misconnect or reverse connect. If the wrong lead is connected, it may cause damage to this circuit board, which should be re-tested again before use.
2) When assembly, the protective plate is careful not to directly contact the surface of the cell to avoid damage to the cell. Ensure the assembly.
3) In the process of use, pay attention to the lead head, soldering iron, solder and other components do not touch the components on the circuit board, otherwise it may lead to damage to the protection board.
4) The use process should pay attention to anti-static, moisture-proof, waterproof and other measures.
5) Please follow the designed parameters and the conditions of use during the use process, and do not exceed the relevant values in this specification, otherwise it may lead to damage to the protection plate.
6) After combining the battery pack and the protection panel, if there is no voltage output or no charge for the first time, please re-check whether the wiring is correct.
