How to add battery monitor script to systemtray or toolbar?

Dear All

I am using fluxbox 1.3.5 on FreeBSD 10.1.

I have a little shell script, called batt, that gets battery info 
(percentage charge & estimated time left) and echoes it out like, "38% 
(3:35)".

I would like to have this displayed in the fluxbox systemtray or toolbar.

- which is the right place?
- is it possible?
- how should it be done?

I can find no documentation on this.  I have looked at the fluxbox web 
site and the wiki on github.

With thanks and best wishes

Ivan
