Guide
The first step is to solder the battery control module ontop of the regulator, it will be tacked down with three points that will connect to the pins on the regulator.

Once you've got the three points of the BCM (Battery Control Module) soldered, you will then need to remove fuse F1 from the board. To do this, we recommend keeping one leg of the fuse soldered so that if you ever choose to undo the mod, it can be placed back.

Next we will want to tin and solder the wires to the IN and OUT pads on the BCM, they will then be connected to the pads that we took the fuse from. IN will go to the right pad of the resistor, while OUT will go to the left.

Once that is done you are technically done with all of the electronics involved in this mod. Depending on which shell you used for your mod, you may have to trim the battery compartment so that the battery can fit. We used flush cutters to remove the bulk of the plastic and then followed up with a rotary tool to smooth out the plastic.


After you've cleared the room for the battery, you can run the wire through the hole in the battery compartment, it then gets plugged into the BCM. Simply place the batteries wire overtop of the connector and press down gently.

From this point, you can put your console back together as normal!
