Most of the folks that got screwed purchased from American companies and not the Chinese companies. Go figure. There are plenty of Cells in the US that you can actually go buy and pick up yourself. If you go yourself you guarantee you will get them. Actually most folks who are selling them are actually selling them and delivering them. That is good news. There will be plenty of the CALB Grey Cells to be had too.
From the reports coming in they are providing pretty good performance power as well as capacity. All good.
You will soon want lithium after a bit of time on the lead sled. I give lead 2 years reasonable use for the life. Giving much more is not really an option.
