When you said, "Not my business, but I hope no one is doing that in a building I might live in."
Pretty much you are saying I have these in a building somewhere where people would be at risk.
Right there.
I'm not sure why you assume these batteries are stored in a dangerous location. I have them because my Dad died and I got them.
And also the assumption they are dead batteries is incorrect; pretty sure only one is. He tested them all when he collected them. All I have tried, except the one in...
If there is a fire, I think you are already going to be suffering devastation. I use LIPO's for FPV, they are a good measure more dangerous than li-ions but both should be respected.
I grew up with drip style, learned to pour well by age 15.
For the last couple decades I have had an espresso machine, it is the best coffee method. Bean quality is extremely important too though, just like weed :)
i actually tidied up the bottom left corner too, so no cells can touch each other at all.
I thought the wrapped wraps were iffy ya. I can check the charge and discard those few.
Please do. They have been sitting like this for about ten years I reckon, no issues.
I use about 8 of them I have somewhere else.
You should see my pile of 4S and 6S LIPOS :D
