Valence batteries I got for $200 was a useful bargain. I was afraid that the

Those $100 listings as others have mentioned are used cells. You'll find that
based on their tested capacity they're not a very good deal also.
As I mentioned, the market rate is about $180/kWH for new cells, sometimes
you can find a better deal on new old stock or bulk buys. I try and maintain

Check out Jehu Garcia on YT. He often organises bulk buys of cells.

Where are you finding cells for $1 each? Going rate for 18650s (new) is
$180/kWH or so, which for a typical 2.6AH cell would be $1.73.

Prices are around a dollar a cell. What is a good voltage 3.7 or 3.2. What's

larger cells for two dollars. I have several projects that need. Batteries.
Any videos or books that might be a good learning experience? A
