I’m having an electronics wiring issue. I am trying to make a battery bank to recharge phones and run other things as needed.
I’m using Ni-MH batteries as the Lithium batteries won’t fit in the space needed. At first I tried a charging circuit that was intended for a 4.5v Lithium battery but it won’t work. It can charge but not charge a phone. I thought it may be that the circuit is designed for 4.5v and may see less then that so cuts off power to protect the circuits.
I did searching for info on cell phone changing and only found a reference of not charging more then 4.2v. I found info for iPhones. But these are Android.
The batteries are fully charged. A meter shows power available on the leads. When I take apart a charging cable and metered out the two lines needed. Just those connected to a charger and the phone charges. So no other power in the other line is needed. When I connect the battery the phone won’t charge. I have chargers as low at 3v up to 5v so the voltage doesn't matter. I can’t find any info on phone charging specs or Circuits.
Any ides on what is going on?
