In this video i showed how to assemble a 12 volt battery from 18650 batteries. I explained in detail what the BMS board is for and how to choose it. Using the example of assembling a battery from three sections (3S), you can assemble any battery of the capacity and voltage you need: for converting a screwdriver to lithium batteries or an electric bike.
To assemble a Li-Ion battery, it is best to use the same battery from the same manufacturer. It's best if they come from the same batch.
The BMS board serves to protect against overcharge, deep discharge, over current and short circuit.
You need to charge the lithium-ion battery assembly with a special charger with voltage and current control.
