If you do not use any USB or Mini-PCI ports, it consumes no more than 1.500mAh. So, I guess you can power the eBox for 2 hours with your battery.<br><br>Best,<br>UmutSun, 16 May 2010 05:11:42 GMTUmutErkalhttp://www.roboticsconnection.com/userForums/Topic1513-21-1.aspxHi Danny,<br> I read the Ebox 4300 specs at 5Vdc and 3Amps.<br>This translates in an ideal world to a short period on a 9.6Vdc<br>at 2200mah battery. Ideally one would get 1 hours use from a 3Amp<br>battery. The amperage ratings for the batteries are given for the<br>amount of power they can deliver for one hour. Like you mention<br>this will vary with usage. Also peripherals will effect total power<br>consumption. For instance, a webcam might draw 300 - 400mA which<br>translates to almost 1/2 Amp. Add on peripherals power draw.<br> One must also consider some minimal power loss in the 5vDC<br>power converter between the battery and the Ebox.<br>Short answer, in an ideal world, about 0.73 hours use with a 2200mAh<br>battery. One more note, different battery compositions have different<br>steady current supply over time. Your obvious choices are nicad, Li-Ion<br>and Li-Poly. The later two requiring much more care of use as they<br>can be VERY dangerous. Lead acid or Gel Cell batteries are not generally<br>recommended for our kind of robotics. All these batteries have maximum<br> discharge and recharge rates. Li-Ion and Li-Poly require specialized<br>computer controlled chargers. Li-Poly require under and over charge<br>protection or they will be easily destroyed. <br> Some one please chime in and make corrections if I am off as I<br>have not used a 9.6vDC @ 2200mAh battery with a Ebox 4300.<br><br>Blame my over wordiness on that beer I had for desert :)<br>Fri, 08 Jan 2010 18:16:32 GMTDon Lewishttp://www.roboticsconnection.com/userForums/Topic1513-21-1.aspxIts understandable it can vary based on usage.. I am just looking for an average time.. <br><br>Thanks in advance!Fri, 08 Jan 2010 01:28:29 GMTdannyjrodriguezhttp://www.roboticsconnection.com/userForums/Topic1513-21-1.aspxWhat is the average running time of a 9.6v 2200 mAh battery use solely for the eBox 4300 ?Fri, 08 Jan 2010 01:26:38 GMTdannyjrodriguez
