How do I recharge my 18650 batteries Answered
Hello everyone, and good day!
I am attempting to add recycled laptop batteries to an old radio of mine, making it portable. I Need 12v to run it. I have made a battery pack already, but am worried that if I just use a 12v power supply to charge them, I might ruin the batteries.
also, I want to be able to plug in and listen while the batteries charge. Is it true that all I need to do is to make the input and output at the same point?
I hope this makes sense. Thanks in advance!
