I am unsure what most people do..... myself I have many batteries of diff sizes for diff things... mods etc. and a couple of ego's 1100 Mah for duration, even though I seldom even look at them, but backup is good, I never fall short with set-ups when out an about & Well... that would mean carrying two!!
But a backup or spare at home would at least be a sensible idea...or even a ego battery as being smaller (just in case of emergencies).
