I have a couple of these cell groups from BHU, too, but there was a fair bit more corrosion on mine. I saw some corrosion on a couple of cells in the one pack that you showed, did you try to remediate that area first before building up your larger pack?

I use a dermal to lightly sand the corrosion so the spot welder can hold better.
I was worried about those cells being bad so I took the pack apart and found the cells still have the same capacity as the rest. So far so good.
@@ElectricOHV yeah, the couple of bad ones seemed to test ok, so maybe there just wasn't a good nickel plating on the contacts or something.
Nice video... where did you buy the batteries?
Batteryhookup.com they deal in used batteries so you need to keep a look out for when the right type of cells become available.
@@ElectricOHV Thank you.
