I’m getting this error too now (spaceship_battery:56: bad math expression: operator expected at '100') on macOS 10.14.1. That happened after I connected by device to a UPS.

  if [[ $SPACESHIP_BATTERY_SHOW == 'always' ||
        $battery_percent -lt $SPACESHIP_BATTERY_THRESHOLD || # <-- this is line 56
        $SPACESHIP_BATTERY_SHOW == 'charged' && $battery_status =~ "(charged|full)" ]]; then

$ pmset -g batt
Now drawing from 'AC Power'
 -InternalBattery-0 (id=3473507)	100%; charged; 0:00 remaining present: true
 -Back-UPS RS 900G FW:879.L4 .I USB FW:L4   (id=8126464)	100%; charging present: true

$ pmset -g batt | grep -oE '[0-9]{1,3}%'
100%
100%

Basically $battery_percent is 100\n100

I realize this is closed. But I wanted to comment for future me. Or others that google this. I am getting this and I am 99% certain it’s because I have two batteries. The number that is reported in the error message is the percentage from the second battery. If I new zsh more, I would submit a patch, but I don’t. I’m happy to help test if someone else wants to take a shot
