> FYI, the cost of individual cells has long, long gone below $100 per kWh in wholesale volumes.

Electric bicycle batteries are still $500 for 500Wh (consumer price, but 10x as expensive).

And phone batteries are even more expensive. This is about grid tier batteries or cars where the volume constraints are less tight.

Your sibling commenter jeffbee says they have replaced the cells in an existing battery, so I'm not convinced volume constraints are the problem here.

Wish I could find one that cheap. The Bosch PowerPack 500 is $900 retail and Specialized recently raised the price of the 600Wh pack in certain bikes to $1300. The price is so silly I pried open my obsolete Specialized pack and just replaced the cells myself.
