    Question Voltage Regulation

    I am redesigning a mini-arcade machine, and I would like to make it rechargeable. It requires 4.5v of electricity. I was going to use a pth08080wah regulator, but I was thinking: would I be able to just use a rechargeable 9v battery and a simple 2-resistor voltage divider instead?

    Question Lots of 18650s

    I have a bunch of 18650s from various sources. Is there a method I should use to test their health before I use them together? Any rules about matching capacity? Also, is there a BMS (like the ebay "red battery boards") that would be suited to using many cells together? I'm not really sure...

    How should I charge my 4 18650 cells

    Hello, I have an internal 4 cell 18650 battery pack in my portable, I was wondering the best way to unify them so that they are all charged and regulated from one charge input, and then have a cumulative battery output voltage. I was looking at this board here but I am unsure which points to...
  9. Protection Circuit?

    OK, so I bought a cheap 5 volt power bank designed for charging phones. Inside it was a 3.7 volt, 2200 mah lithium ion battery and a protection circuit that boosts the output to 5 volts.

    Question Battery PCM

    So I have pretty much concluded that the stock pcm my batteries came with is fried. I think my dremel or soldering iron must've damaged it. But I was wondering if anyone has had experience using this one. Any advice would be much appreciated.

    Question Batteries for Portable

    I have been using these batteries for my portable. I also have been using this PCM. Could I just swap the batteries out for these ones to save space, or would I need a new PCM and charger and all? Thanks!
