I've got +/- 40 cheaper gold mount batteries, Ikan IB-L130A, 14.8V 9.0 Ah 130Wh in my inventory. They're in good shape as far as the battery cells, but the outside cases are getting beat up and cracked. Ikan doesn't have spare/loose cases for this model anymore. Does anyone know of a generic case that I could re-home the cells into? Or maybe a 3d printed design that would work? I know it's a long shot. Just trying to keep the inventory functioning as long as possible.
