    Also they all have to be 0.1 v from each other otherwise the “whole thing goes south” sounds scary and is now kind of making me rethink my plan of putting up collection boxes outside of high schools and building a battery for my house out of them.

        this is only true if they’re 1s. but all bets are off if you have cell groups. God forbid you use them to make anything remotely useful like an ebike battery or home power storage.
