Regarding the painsticks Boimler says that no one can survive being shocked with 30,000 volts, which is not true. Voltage isn't the main factor that makes an electric shock fatal, current is. Anyone with a basic knowledge of applied physics, like a graduate of Starfleet Academy, would know this.
Currents above 75 milliamps can potentially be fatal, so if the current is well below that a very high voltage is rarely fatal. A standard 120 volt line with a 15 amp current is going to be fatal, but a 30,000 volt charge with only a few milliamps will be painful but easily survivable. For example a Taser usually has 50,000 volts but only about 1.9-2 milliamps; fatal Taser shocks are very rare, the only known Taser related deaths were in people with preexisting cardiac issues.
