>take a fuck ton of power for some reason
everything takes the same amount of power. Five seconds at night costs 1 energy from a battery, and nights last four and a half minutes (54 energy). The one thing that the game doesn't really mention about battery power is that most every connection, besides extensions and plug strips, counts as one extra power sucked per 5 seconds. Standard batteries can power one thing for most of the night, but will eventually fuck things up if you're trying to refrigerate or contain something, because it only has 50 of the 54 needed for the last 20 seconds of power. If you daisychain batteries back to back, the backmost battery will take the brunt of the energy being sucked, and the batteries in front will count towards how much energy is being sucked on top of everything else on the electrical grid. There's better guides out there somewhere but here's a quick example.
