both flex volts have similar issues, showing voltage of 18.3 and 20.1v on voltmeter but neither will power a tool, and even though one looks like it charges, it doesn't take long to reach "full" and then still wont power anything. were used extensively but once started being faulty went in the van and didn't come out again until now! the smaller battery is at 14.7 wont charge or power anything.
