so i read an article about laptop batteries being made of 18650s in series and happened to have an old laptop laying around pulled off the battery pack ripped it open and voila 8 green 18650s a little bit of referencing on the interwebz tells me they are made by Sony my question is would they be ok to use in a mod? all i have right now is egos but if i have these batts laying around that i could use i would probably be more likely to spring for a mod a bit quicker any thoughts?
