Battery Protection Board，Compatible for Dewalt，DCB609 Lithium Battery Charging Protection Circuit Board

Precautions for use and assembly:1) When welding battery leads/sampling points, be careful not to connect them incorrectly or in reverse. If a wrong connection is found, the circuit board may have been damaged and needs to be retested before it can be used again.2) During assembly, the BMS should not directly contact the surface of the battery cell to avoid damaging it. The assembly should be firm and reliable.3) Electronic devices used for welding must be reliably grounded, and attention should be paid to electrostatic protection to prevent damage to the protective board caused by electric leakage and static electricity.4) Be careful not to touch the components on the circuit board with lead wires, soldering iron, etc. during use, otherwise it may burn out the circuit board.5) During use, attention should be paid to anti-static, moisture-proof, and waterproof measures.Colour:Random ColorMaterial:PCB+PlasticPackage Contents:1 x Battery Protection BoardNote:If you need more models of vacuum cleaner accessories, please contact us.Welcome to my shop, dear buyer!

• Extend battery life: Replace the battery protection board to avoid overcharge/overdischarge, reduce battery loss, and extend the overall service life of the battery.
• Restore battery capacity: The old protection plate may misjudge the power level, and replacing the vacuum cleaner battery protection plate can release the true capacity of the battery and improve the time of single use.
• Reduce battery hibernation: Problematic old boards are prone to accidentally trigger sleep mode, replace the vacuum cleaner's battery protection plate to avoid sudden "fake death" when in use.
• Reduce the frequency of maintenance: The old battery protection plate of the vacuum cleaner with problems can easily lead to failure, and replacing the battery protection plate of the vacuum cleaner can avoid frequent repairs due to the failure of the protection board, saving time and money.
• Fixed the "virtual power" issue: the old battery board may show full power, but the power will be lost as soon as it is used, and the power level display will be more accurate after replacing the vacuum cleaner battery protection board, so as to avoid misleading users. Avoid sudden power outages while working.
