    Samsung 22p battery testing it with capacity checker and is something wrong

    I recognize the ZB2L3 board you are using, I have used the same myself and from what I can see in your photos, all seems to be correct.

    Remove glue/rubber from harvested batteries?

    Thank you, @hbpowerwall , @italianuser , @OffGridInTheCity , @Wolf and @Korishan for the tips and suggestions. Rewrap it is then :) Would like to buy from 18650ed but I live in Sweden and the freight and importtax makes it very expensive... The Arduino/barcode setup sounds very interesting!

    Remove glue/rubber from harvested batteries?

    Hi, how do you remove the white/black glue/rubber-stuff from your harvested batteries? Scraping it off with a plastic pry tool, like you use to open a mobile phone/laptop, sometimes rips the heatshrink. Do you use a solvent or what do you do? All suggestions appreciated.
