Combine (relay?) multiple cellphone batteries for one large powerbank Answered
I rarely trade my previous primary mobile devices when upgrading; as a result, my cache of obsolete phones with perfectly useable batteries is a dozen, give or take. I'm sure not many, if any, tinkerers, modders, hobbyists, etc., would recommend such a project, as these batteries can be unforgivably volatile if used any way other than their manufacturer's suggest, and sometimes even then. So let's assume we've all been warned; no need to reply "don't...". that being said, has anyone here ever attempted anything like this, or know, or heard of someone who has? if so, links would be much appreciated.
fyi, i ask because i'm considering trying to mod an old rc car into a wifi/app controlled car, and repurposing as much of my neglected junk as i can to do this, would be soo satisfying.
