[PDF Version]To build a 12V battery pack, you will need: 18650 Cells: At least three cells connected in series. Battery Management System (BMS): To protect against overcharging, over-discharging, and short circuits. Nickel Strips: For connecting the cells. Spot Welder or Soldering Iron: To secure connections.
Now let's plug in the numbers. The standard voltage range of an 18650 cell is: For a 12v battery pack, we'll use the nominal 3.6v figure for our calculation: 12v ÷ 3.6v = 3.33 Rounding up gives us 4 cells in series. However, we can squeeze a bit more capacity out of our battery by running 3 cells in series (for approx 10.8v).
To make the battery pack, you have to first finalize the nominal voltage and capacity of the pack. Either it will be in terms of Volt, mAh/ Ah, or Wh. You have to connect the cells in parallel to reach the desired capacity (mAh ) and connect such parallel group in series to achieve the nominal voltage (Volt ).
To build a 12V battery pack with 18650 cells, connect four cells in series (3.7V each) to achieve approximately 14.8V nominal. Use appropriate battery management systems (BMS) for safety. Ensure balanced charging and consider using protective cases for safety and longevity.
