The V6 and V7 battery packs don''t do any sort of handshake with the vacuum, and in fact pulling the vacuum trigger literally just actuates a switch on the battery that tells the BMS to enable output.

Be aware that most "pack" 18650''s do not have the raised bump on the end which makes them suitable to use individually like an AA battery would have, for instance. So if I want to use them individually in devices, I put a big blob of solder on the end, then use some digital calipers and the beltsander to sand it down to the correct height.

The tools you use to disassemble a lithium-ion battery pack can be the difference between salvaging a bunch of great cells and starting a fire. 5 pack of flush cut pliers. Perfect for removing the nickel strip that is attached to cells when salvaging.
Remember, battery packs are made of many cells that are grouped in a specific way. So, if one cell dies, it will bring down the cells that it is immediately attached to. This is bad news for the cells in that group but it's good news for the rest of the battery pack. It generally means that the other cell groups are just fine.
Whatever the main battery pack is electrically connected to, remove it. Remove any circuit boards, regulators, lights, wires, or anything else there is, and get it down to the raw battery pack. Step 2: Mask off the area that you are not working on with Kapton tape or any other easily removable adhesive insulator.
Using a multimeter, test each cell within the battery pack. It will help you to identify any faulty or underperforming cells. Check the voltage and internal resistance of every cell to determine its health. Replace any defective cells with new ones. But ensure the same type and capacity to ensure the proper functioning of the battery pack.
Building a battery pack from individual cells generally requires a degree of dexterity, electrical expertise, and a spot welder. As you can see from the old unwrapped battery pack in Figure 3, the five green cells are neatly connected at the positive and negative contacts via thin, spot-welded nickel strips.
You have to be extremely careful when breaking down a lithium-ion battery pack. If you're not, then you will easily short out cells. When you are working on the cell level, there is no BMS there to protect you. So proceed with caution and safety first!
