DIY - Power Bank

This weekend was rather an interesting week end.  Some progress with respect to work from waste.   I had a fake Xiaomi 20000 mAH Power bank which worked like a 2000 mAH, This weekend I started with dismantling the old LG laptop.  Once dissected, I got an Idea to take out the battery and then make it into Power Bank. 

 

Once I opened the fake “Xiaomi 20000 mAH Power bank” which I got from the Market, I found that there was only one battery instead of 8 connected. Rest of the 7 battery were dummy.  I then replace them with the one I got from the Laptop battery and then connected in parallel. Now I have a spare power bank at home, and well It charges my phone.
