  1. Nov 11, 2016 #1
    Hello,
    I am made a powerbank myself with li ion battery. I used boost converter and everything is fine, charging my phone. But the li ion battery and my boost converter is getting really hot while charging my phone.The battery capacity is 4400mah. I dont know the reason for such temperature. Please share your experience and theories.
