Voltage Stack (バンドルボルテージ Bandoru Borutēji?, lit. "Bundle Voltage") is a technique in the international release of Kingdom Hearts Birth by Sleep and Kingdom Hearts Birth by Sleep Final Mix. It involves teaming up with friends and jolting enemies with electricity. By lining up the markers with the analog stick, it will trigger an explosion. It is most effective during Mirage Arena battles.


In Kingdom Hearts Birth by Sleep, Voltage Stack is an Advanced Friendship Command that takes up three slots in the Command Deck, has a maximum level of 1, and a normal reload time of 40 seconds.
