</div>

<p>Your battery can be attached with a wire tie or Velcro (not included).</p>

324

<p>A 6VDC battery will power the robot fine, however as it discharges the SSC-32 may reset even though there is still sufficient power for the servos. A 7.2VDC battery lessens this effect but is slightly harder on the servos.</p>

325

<p>For maximum run time, power the VL input from a separate 9VDC battery. Remember to remove the VS=VL jumper to isolate the two supplies — the 6V or 7.2V battery is still required.</p>
