What is the average running time of a 9.6v 2200 mAh battery use solely for the eBox 4300 ?

Hi Danny,
I read the Ebox 4300 specs at 5Vdc and 3Amps.
This translates in an ideal world to a short period on a 9.6Vdc
at 2200mah battery. Ideally one would get 1 hours use from a 3Amp
battery. The amperage ratings for the batteries are given for the
amount of power they can deliver for one hour. Like you mention
this will vary with usage. Also peripherals will effect total power
consumption. For instance, a webcam might draw 300 - 400mA which
translates to almost 1/2 Amp. Add on peripherals power draw.
One must also consider some minimal power loss in the 5vDC
power converter between the battery and the Ebox.
Short answer, in an ideal world, about 0.73 hours use with a 2200mAh
battery. One more note, different battery compositions have different
steady current supply over time. Your obvious choices are nicad, Li-Ion
and Li-Poly. The later two requiring much more care of use as they
can be VERY dangerous. Lead acid or Gel Cell batteries are not generally
recommended for our kind of robotics. All these batteries have maximum
discharge and recharge rates. Li-Ion and Li-Poly require specialized
computer controlled chargers. Li-Poly require under and over charge
protection or they will be easily destroyed.
Some one please chime in and make corrections if I am off as I
have not used a 9.6vDC @ 2200mAh battery with a Ebox 4300.
Blame my over wordiness on that beer I had for desert

Hi Danny,
I have eBox4300. 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.
Best,
Umut
