50 Samsung 2600mah cells in holders

Here we have holders with 50 Samsung 18650 cells inside. We were testing opening up some modem batteries and we placed the cells inside these holders. All cell have voltage and should test fine. The cells are not all the same voltage so you will need to charge each one up before connecting in series. Selling these for cheap and we only have a few available. 50 cells with the nickel removed for just $45. 90 cent cells.
