Reminds me of this thread: Source for Eremit 18650 batteries
Maybe @minute can resell the eremit batteries at shop.mntmn.com? Since you already have one set of dead batteries, you are probably also interested in the protected battery board: MNT Reform Battery Board (protected) - MNT Research Shop
If you could also by the cells from mntmn.com, then you could buy a set of cells and the upgraded board together.
