Adds 12V rechargeable Lithium Ion battery to the Numark PT01

Parts needed:
12V rechargeable battery
DC plug (2.1mm x 5.1mm)
Picture hanging Strips (optional, or can be substituted):

-Disconnect the rechargeable battery from the PT01, when powering the PT01 from a wall supply.
-Charge the battery by disconnecting the DC plug from the battery, and charge it using it’s supplied charging wall supply.
-The battery power switch must be on, while charging the battery (explained in the battery instructions, but are in Chinese)
-Turn the battery power switch off, when not in use to save charge (not required).
-see LM7805 data sheet for more info on the PT01 regulator (actual part number is LM7809)

-Connect Wires to the PT01 Power Supply Input
1. On the PT01 power supply PCB, solder a GND wire (black) to the center pin (pin 2) of the LM7809 regulator (see pic_1_PT01_regulator)


-Connect DC Plug
3. Confirm whether the center pin of the DC plug needs to be + or – by reading the label on your rechargeable battery. The center pin is + for the battery listed above.
4. If using the battery listed above, solder the red wire to the center pin of the DC plug (see pic_2_DC_plug)


5. If using the battery listed above, solder the black wire to the outer ring of the DC plug (see pic_2_DC_plug)

-Mount Battery
6. The battery can be mounted however you like. I like the using the picture hanging strips listed above. One strip is mounted on the wall of the PT01 within the battery compartment (sticky side against wall), and one strip gets mounted on the battery (sticky side against battery). I put a set of strips on 2 sides of the battery (example: side and top). This is rock solid, and allows the battery to be removed, if necessary (see pic3_Battery_placement).
