I had to go look after I read this topic because I didn’t know he had them. What I see is shipping starts at @ $5 and goes up about $1 per cell as you add them up in quantity. So for 10 Tesla 21700’s that would be about $48(Shipped to the U.S.) Seems fair if they are legit. As for those Tesla 21700’s, I’m a little sceptical because the positive end doesn’t look like any Tesla battery I’ve ever seen before. Could be I’m mistaken. I’ll just have to wait for some reviews. I have 10 coming from Mtn. Electronics now. I know for sure they are legit.
