Unused Batteries: Lithium (type) 18650 (Bellevue EH7)

Hello, I'm hoping to find a few High Drain LI-on batteries. They are the most common Li-On cell found in all kinds of larger batteries, like e-bikes, vaping devices, power tools or lawnmowers. They can be dangerous if over or under charged so I am looking for some that still have a little charge in them. Please let me know if you have any you no longer need. Many thanks.
