Insert probe and remount fan

The fan enclosure will need to be notched to allow free passage of the thermal probe. The probe is coated with a dab of the thermal compound on the active side, and is inserted between the black plastic battery retainer and the battery with the thermal probe active side toward the batteries. The probe wires are zip tied to the battery wire, and the fan is remounted. Finally seal the gap around the fan to make the fan more efficient at drawing air through the pack.
The rear install is now finished. Leave everything open until we do the powerup test.
