@JRE I guess I forgot to give the nominal voltage and charged(max) voltage for the batteries. They are charged at 4.20 - 4.22 volts. There is a tiny voltage difference which doesn't make a difference overall in operation. My USB will allow for up to 20 watts output and minimum of 5 watts output.
@JRE Can you familiarize me with what USB protocol is?
@JRE I intend on getting my voltage and current boost converters from eBoot, and GoWoops through a 3rd party Amazon carrier. I do have enough in the budget to destroy a few amplifiers. Logically down at the basics it seems that it could work, but sometimes those logical basics are wrong in some cases. That's why I asked.
@JRE I saw your message about the transformers. I make mistakes like that as well. Even after I've looked at it several times. :)
@JRE The speaker runtime test was the speaker turned all the way up, and the volume on my phone all the way up as well. So it was running at max. So theoretically it could run longer since we know that it uses more energy when turned up louder.
@JRE I'll connect the 3rd speaker to it and tell you how it goes once I have the time. Which today is pretty slow going, so I'll most likely do it in an hour or less from now.
