Yes, the 030 does drain everything out of the packs, its just that it does it at a high amperage. Even when the cells are at a low voltage, they are still discharging at a high amp rate which can be harmful torwards the cells. What cells are you planning on dead shorting?
Definition of dead shorting- once the pack is drained to 0.0v, a wire is applied across the positive and negative in order to keep the pack at 0.0v. Otherwise, the pack will return to a voltage around 7.2v. This practice was very popular when the gp3300s were out, but has almost with the release of the newer cells since there appears to be no gains by dead shorting them.
