      REV Robotics (REV-31-1302)

The main power of a robot comes from one 12v battery. The battery may be one of
the batteries shown above. Refer to section ``<RE03>`` in the 
:ref:`Game Manual Part 1<manuals/game_manuals/game_manuals:game manuals>` 
for exact information on allowed batteries. Note that it is typically allowed
by ``<RE15>`` to replace the connector on the batteries, provided the in-line
fuse on the battery is preserved.

.. warning:: 
   Be sure to remove the 20A fuse from the in-line fuse holder prior to cutting
   any wires/connectors if/when replacing the factory default battery connector.

Power Distribution Blocks help to distribute the power to devices such as
Control Hubs, SPARKminis, and more.  
See :ref:`Game Manual Part 1<manuals/game_manuals/game_manuals:game manuals>` 
for a description of legal Power Distribution methods. The REV XT30 Power
Distribution Block shown is only one option for distributing power, and is
not the only legal device for power distribution.
