I'm not finding any of the quality 18650 batteries on Ebay right now. Don't know why?
There are some of the lower quality 18650 batteries available, like UltraFire. I have some of those
and they're ok. Most of the time on Ebay, I find the ones with lots of "Sold" with some "Available"
to be reliable.
I purchased my Panasonic NCR18650 from: (genele3) on Ebay. They have none right now.
but lots of the cheaper ones. I find genele3 to be reliable.
There are internet battery stores on the internet that still have quality batteries, but
I haven't done any business with them.
This is the link to the 5 volt solar panels I mentioned, and at 2amps, they are perfect for charging
small items. They need some work to complete, but they are really some awesome panels for little jobs.
Ten panels for $25.00!!!
After I hot glued a piece of plexiglass to the bottom, it becomes very durable.

Sorry, I'm not much help on the quality batteries at a reasonable price. I think those days
are gone for now. I purchased my last 18650 batteries about one year ago, and the price was
very reasonable.
If I needed some lesser quality 18650 batteries, I'd go back to genele3.
I haven't check on Amazon, as I done care for them.
