When welding the wire, you can't touch any components on the board, and don't intentionally short circuit. When welding batteries or charging, as long as a single battery exceeds 4.

If the "" resistor is heated seriously too hot to touchplease check whether the wrong connection is made. Please allow mm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding. Note: Please allow mm differs due to manual measurement.A BMS is a really important safety feature to add to a lithium battery. Not only will it make your battery safer by protecting your cells from over and under discharging, but it will also make the entire charging process much simpler.

The first step is to install your BMS. There are two main sets of wires you need to install, the thick wires and the thin wires. Not every BMS is the same, but most are similar. Your BMS will likely have 3 thick wires, or 3 pads to solder on your own heavy gauge wires.

These are the B- P- and C- wires or pads for adding wires. Be very careful not to let the solder blob touch any other components on the BMS board, as many BMSs have very small solder pads that are close to other components.

You generally want to use a fairly heavy gauge wire here such as 12 or 14 AWG. This wire will carry the full power of your battery during discharge. If you used a single wire clamp, just crimp the wire inside of the clamp using a wire crimper preferred or a pair of pliers less ideal, but it works.

If you used multiple wire clamps, you can either strip a section of wire further down the B- wire, or you can use two wires spliced together, with one end crimped in each connector and the other ends reaching back to the B- pad or B- wire on your BMS. Now your BMS is connected to the negative terminal of your battery. I like to add a thin layer of foam or plastic below the BMS too, just to add a second layer of insulation between it and the battery cells.

Next, I like to add my balance wires. These are the thin wires with the white connector.

Your BMS will either have the same number of balance wires as series cells in your battery, or one more. Our BMSs sold in our shop have one more wire than the number of cells in series. If your BMS has one more wire than the number of cells in series, then all the balance wires will connect to the positive ends of the parallel cell groups except for the very first one which will connect to the negative end of the first parallel cell group. If your BMS has the same number of balances wires as series cells, then each balance wire will connect to the positive end of each cell group only.

Then place the bus bar back on top of the cell, ensuring that it contacts the balance wire, and finally replace the nut and tighten everything down. You could also clamp the balance wire between the busbar and the nut, but this would add some resistance to the flow of electricity through the battery, as the electrons flow through the threaded post, into the nut and then into the busbar.

By placing the balance wire below the busbar instead of between the busbar and the nut, you allow the main flow of electricity to bypass the sense wire during pack discharge, while still allowing it to remain in electrical connection. Alternatively, you can also solder the balance wires directly onto the busbars. Either way works just fine. Continue with each successive balance wire by connecting it to the positive end of each successive cell. For our BMSs, the second balance wire the first thin red wire will be connected to the positive terminal of the first cell group.

Then the third balance wire connects to the positive terminal of the second cell group, and so on.

The last balance wire should connect to the positive terminal of your last cell group. The P- wire is the negative discharge connection, so that will plug into whatever device you are powering, such as an electric bicycle or skateboard controller, an inverter, etc. Our BMS already has this wire soldered to the BMS, so you are essentially done at this point, unless you want to lengthen that wire by soldering on a longer piece.Packaging should be the same as what is found in a retail store, unless the item was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.
