WTB: Batteries - 18350, 18650, 21700 and/or 26650, and, possibly, a charger (I'm in the U.S.)

I was thinking about buying some batteries, but I am not sure where to try to buy them from. So, before I went and bought some new batteries from a shop, I thought I’d ask and see if anyone has any extra batteries that they might be looking to sell/trade.

I want to try to get some 18350, 18650, 21700 and 26650 batteries, if possible. Depending on the prices, I would like to try to get a few of each, if I can afford it.

I may also be interested in buying a charger for the batteries, as I currently only have the Sofirn chargers that come with their flashlights, or have to use one of my flashlights with built-in charging.

I also have a Luminop FW21 Pro that I might be willing to trade for some batteries, if the right deal presents itself. And I live in the U.S., in Arizona, for shipping purposes.

So, if you have some extra batteries and/or a charger that you’d be willing to sell, or trade, feel free to let me know. Thank you.

Thank you very much, for the reply and the link to that thread. I was not aware that there was such a thread, but I will definitely check it out.

If you're looking for 21700 cells, Molicel P42A are some of the best for high discharge cells, and they're not that expensive either.

Selling used batteries presents a problem for the seller. There are very specific regulations about shipping Li-ion batteries and the consequences for ignoring them can be very expensive. The 18650 batteries I buy shipped by US mail always come double packed. There is a plastic case surrounded by foam and packed in a cardboard box. There is also labeling required for the outside container, specifying ground transportation. I’d buy new if possible as commercial shippers know what is required.

I was looking into the Tesla 21700s. I can’t convince myself to do it. Buying new is the best route, imho. In this way you know everything about the battery and won’t be risking damaging your lights/charger/hand/house with a bad cell!
