9.6V250mA to a 9.6V 2000mAh battery pack for my rc plane?

With electronics, they're typically built for a specific voltage.  Always stick with the same voltage rating.\n\nThe mA-hr rating refers to how long the battery will last.  It's the product of the current (how much power the battery is providing) and the total time at that current.  For example, a 250 mAh battery will last for one hour when providing 250 mA.  It will last 0.5 hrs when providing 500 mA.\n\nThe bigger the number, the longer it will last.

Yes connecting a battery would charge the two plates - like a capacitor.   You have not told us what your science project is?  I would guess that you may need a much higher voltage than the battery can provide - it depends on what you are trying to do.

go to radioshack...they sell basic instruction manuals, circuits and all the bits you'll need

google it??  I dont think there are any, a 9v battery is not strong enough to be fatal by itself.  actually, maybe i was wrong thinking that, if the darwin awards can be believed.

I don't know exactly what you're up to, but as to how to connect the batteries...the usual way is to get a battery holder (Radio Shack sells them).  You'll have to solder the wires to the terminals, of course (if you don't know how to solder, you ought to learn!)

You need the internal resistance. Then based on the amperage due to load you can figure the I^2R loss in watts for the battery.\n\nThe internal resistance can be determined by adding a resistive load to the battery and monitoring the voltage. The point at which the voltage starts to drop equals the internal resistance of the battery.

For part 3 - "BEC" or Barrety Elimination Circuitry (I think) is a wiring that takes power from the main battery (think of the main battery pack on an RC car) instead of needing a piggy back pack for the ESC, so as I understand it you need the 4 cell pack to run the ESC. If I could get a hands on ans actually see it that would probably help.

Have a look at Batteries.com.  You can also shop around at Froogle - put in "battery" and your laptop make and model.

You need copper, and any sized battery. Then you need to do some playing around with it. Or you could just go here and do what they tell you.

You're going to want something that gives your battery less than about 130 W or you'll cook it.\nThat would be about 150 to160 W panel depending on brand and how it's connected.\n\nYou may want to oversize this a bit given that your panel won't be collecting all the sun possible mounted to the back of a scooter.  If you're not overly concerned about battery life, try a 200 W panel (gotta warn you though - it ain't gonna be small)

1 Ah = 1000mAh\n\ntherefore 20 x 50mAH = 6 volts at 1000mAh.\n\nHow many volts did you want?

1000 watts make a kiolwatt

A VRLA battery is a basic lead acid battery and an internal between one or a number of cells will render it useless.  An internal short will prevent that cell from working (will produce no EMF) and so the output voltage of the battery will be reduced by the amount that would be given by that cell.\nBattery no good I'm afraid and no chance of recovering it.\nP.

Head over to  http://www.nabcorp.com/int.htm to get the deals on those batteries. \n\nGood luck. - Stuart

You would wire them in parallel so that the voltage would be the same across each of them, because in parallel the amperage increases, not the voltage.  If you were to wire them in series, then the voltage would add to 48 volts, which would destroy your electrical system.  You would likely need a better alternator to handle the charging of all of these batteries, too but I'm not sure on the specs of an alternator that you'd need.
