This is some of the batteries i got last month from going around and asking politely from many locations and picking up some from locations that told me they would place them to the side for me...

The lithium batteries for your power wall i understand man. Good job on saving money on those.. But these old laptop batteries?

If you don't mind may i ask what you use them for? Thats a lot of junk that could be flammable if i understand correctly.

I open them up and remove the 18650 cells, then i test them in clusters to find out the cells health and capacity with a bulk tester.

I have used them for numerous projects, i built 2 batteries for my electric assist catrike bicycle i ride weekly around town, i built 5 powerwalls so far that are all linked together, and i replaced the batteries in my RV with these so when i travel i have far superior capacity compared to the old 4 lead acid batteries it had previously.

In regards to flammable, they are very stable cells if you use safety precautions... i put a glob of hot glue on the positive end when i finish testing them and sort them by capacity, just so there is far less chance of a short happening in the sorting containers...

My current reason for collection more is im currently building a 3 wheel motorcycle that i plan to power via electric motor.
