hey guys. me and my best friend got into vaping this past semester of college to quit analogs and now are in love with it as a hobby. I've been into mech mods and rebuilding for a while but my friend is just getting into it. he's ordering his first mech this weekend. i have a bunch of sony vtc5 batteries and i said i would send him one to save him money. how should i go about shipping the battery to be safe? should i discharge it? fully charge it? package it in anything specific? if it matters met friend lives about 3 hours away and we are both in maryland so it doesn't have a long journey to make and won't be changing climate.
