DCB609 Lithium Battery Plastic Case BMS PCBA For DeWalt 20V/60V DCB606 DCB612DIY (semi-manufactured goods, No battery)Advance notification:(1). To use this product, you need to have some professional knowledge and experience. We do not guarantee that you can use it well.(2). It requires you to have specialized assembly tools such as spot welding machines, multimeters, and compatible chargers, etc. If you do not have these tools, please do not place an order!(3). This product has no after-sales service. After placing an order, it will not be returned! No refund!No after-sales!No refund!No return!Please purchase with caution!3. The size and color in the picture are for reference only. The actual received goods shall prevail. If you raise any objections based on "color and size differences", please do not purchase!4. The label and nickel may not be exactly the same as shown in the following picture and may change with the batch. Please do not mind! Do not purchase if you mind.5. The product does not include batteries. You need 15 pieces of 18650 power lithium batteries with a discharge coefficient >= 15CNo Original, 100% Brand New, No Battery Cell !!!!!!Notes:After combining the battery pack and this protective board, if there is no voltage output during the initial power on, please activate it with a dedicated charger. If there are still any abnormalities, please contact us.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. It can fill 15 pieces of 18650 power Li-ion batteries, But this is plastic shell, there is no battery inside.Preparation before assembly:(1). If a new core is used, please note:          a. 18650 power lithium battery core must be selected ( Discharge coefficient >= 15C ) ,          b. A group of 15 cores must be equipped with resistance and capacitance to make their voltage the same.(2). If the old battery is repaired, please test the voltage at both ends of each cell. If the voltage is different, please charge each cell to the same voltage value.Very important:Ensure that the voltage of each cell is the same before welding PCB.Package include:Plastic Case( No Battery, No Cell! )ScrewSpringCircuit Board(PCB)Nickel sheetStickers   As the following picture:no battery cell!!!!!!!!! Please note: batteries are not includedNote(Very Important!!!) :1. There are no batteries in the package !!!!!!2. If you need batteries, please don't place orders !3. If you don't have the knowledge of battery assembly, please don't place an order !
