• Make sure all the batteries are at the same voltage and same capacity
• Now Assemble the holders
• Now put one by one cell into the battery holders
• Now use Kapton tape to tape it all

Kapton Tape - it is used to avoid the heat basically it is a heat resistance tape

Note - Please see the images for better understanding

For Welding, I Used Spot Welder don't use soldering Iron It may damage your battery

• Now cut down the Nickle plated strip tape at the Right Length
• First, make a pair of 3 parallel battery as shown in the picture
• and then connect all the 4 pair in series
• This connection is called 4S 3P
• You can also see the connection diagram above

4S - Stands for 4 Series

3P - Stands for 3 Parallel

Note - Please see the images for better understanding

To insulate the BMS From Battery I used 2-3 layer of Kapton Tape and Dual Sided tape

Note - Please see the images for better understanding

I used 22 AWG Silicone wire and cut it to the right length and soldered wire according to Wiring Diagram and used XT60 As Output

Note - Please see the images for better understanding

The Battery Has Been Finished I used a 55 Watt Car Headlight Bulb H4 to Test It and it Glows Very Bright

That's all for today guys!
