The battery pack was reading ~ 30 V, far too low to be caused by an otherwise functional but depleted battery. Bad news, the whole pack will need to be replaced (I *could* replace the offending batteries with working ones, but this would require an effort beyond what I can justify to myself).

Presumably, I thought, some of the batteries in the pack would still be functional and may yet have a purpose, so I carefully broke them out of their assembly for testing. All but 4 were usable. Two were totally dead, giving voltage readings of ~ 2 V, and another two had a layer of oxidized metal at the terminals, but gave otherwise normal voltage readings. I disposed of all four, leaving me with **six (6)!🙂** working batteries.

These batteries are not especially good quality. In fact, they are dirt cheap, low capacity (2000 mAh) and it is no mystery that they died. I don't care, I'll keep using this garbage anyway. My flashlights use 18650 batteries, and it will be good to have them around. I discharge them to storage voltages, record it in my battery management spreadsheet, and say goodbye for now.

I was intending on buying a replacement **battery pack** but I was instead gifted an **entirely functional replacement hoverboard**, at a price I am told was less than the price of a new battery pack alone due to strange shipping prices for batteries. Many such cases.

🔋 Done.
