There isn’t one if the battery they’re rewrapping is available in your country. There are some smaller
batteries like 14500 and 350 that haven’t been popular and rewraps are the on,y way to get the cell inside. Like the mxjo 350 and aw 14500 I think are both not available cells outside of those rewraps. I could be wrong but I’ve never seen info on what is being used inside them. Which says to me they have a partnership out of Asia for those
batteries. The aw is actually a 340 not a 350 and is pretty low capacity at 650 mah. The mxjo is a solid 700 and the one so bought have lasted forever and were 2/$5
But I think you nailed it. The most important thing is that the
batteries are authentic. Rewraps tens to inflate the numbers for usb ohm cells. Some rewrappers are claimed to have a deal for the “a” stock but that’s bs as far as I can tell.
Have you ever looked into mooch's tests here or on Reddit? His blog here on ecf is brilliant.
