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 don't know the reason for such temperature. Please share your experience and theories.

Yes, I was able to get 1 amp. Last post was genuinely helpful. But again, my battery is getting hot and i don't know why. Any ideas?
 
I'm not comfortable with discussing this here on the PF. It falls under our dangerous topics prohibition. Sorry, this thread is closed.
