Wiring Blocks Batteries
The next step is wiring the battery packs.
We will link the three 18650s in each case, connecting the 3 negative terminals, then the 3 positive terminals together each battery block, will form a cell.
Each negative terminal of one cell will then be connected to the positive terminal of the next.
On the first cell (counting from the bottom), we will add a wire from the negative terminal, which will later be connected to the BM- of the BMS.
On the last cell, we will add a wire from the positive terminal, this wire will be connected later to the BMS B.
Finally each positive terminal of the cells will be connected in order to the BMS.
- cell 1 blue cable,
- cell 2 yellow cable,
- cell 3 white,
- cell 4 green
- purple cell 5
- cell 6 red
The goal is to get the montage below
To solder set the temperature of your soldering iron to 380 degrees
Remember to ventilate if you don’t have a smoke vacuum cleaner.
We will now test the welds, adjust your multimeter as below:
