I just removed my nub. The newer batteries have a gauge on the back to check the charge. I stop using them when they get to two bars and switch batteries. It's odd they had the foresight to add the nub.
If you remove this nub you are going to burn out your tool. The nub is there because your tool doesn't have the correct electronics in it to regulate the 5AH coming oit of the battery. The tool will work fine for few minutes of use bit over prolonged use it will burn out the brushes and maybe even the motor.
