● When soldering the battery leads, it is important not to make any wrong or reversed connections. If you do make a wrong connection, the board may be damaged and needs to be retested before it can be used.
● The protection plate should not come into direct contact with the surface of the cell during assembly to avoid damage to the cell. The assembly should be solid and reliable.
● Take care that the lead head, soldering iron and solder do not touch the components on the board during use, otherwise there is a risk of damage to this board.
● The use process should be anti-static, moisture-proof, water-proof, etc.
● Please follow the design parameters and conditions of use and do not exceed the values in this specification, otherwise there is a risk of damage to the protection plate.
● After combining the battery pack and the protection board, if you find there is no voltage output or it cannot be charged when you first power up, please check if the wiring is correct.
