It will be the case on the bottom of the board that does not have a power button. It is the larger black case and has "BACKFIRE G2" written on it. The battery casing is pictured.
Step 3: Unscrew 3 Bolts on One Side of the Battery Casing
Use the Allen Wrench to unscrew three hex bolts on one side of the battery casing. Insert the wrench into the bolt and turn clockwise, Keep track of the washers that come out with the bolts.
Step 4: Unscrew the 3 Hex Bolts on the Other Side of the Battery Casing
Use the Allen Wrench to unscrew the three hex bolts on the other side of the battery casing. Line the bolts up with the same holes they came out of to ensure that they go back in easier (optional)
Step 5: Flip the Battery Casing Over
Take the side of the battery casing closest to the wheels and flip it over towards the other end of the board.
