You don't want Python or Node to always run on your laptop while on battery. I found no use for BitBar last year when I tried it. You have to use a compiled language to get good performance.
As far as I can tell from playing with it, it updates every few minutes and cannot tail output from a long running process so I don't understand how you had it running continuously. A light Python or PHP script seems fine for providing text to this.
