Okay we're going to teach you something here you dumbass.

You have an n64. You want to power it with 24v or 12v, and the 24v pack is 3500 mAh and the 12v pack is 5000 mAh. This is all just to prove a point.

Let's say the n64 has a power rating of 10 W. Based on ohm's law, you divide this by the voltage to get the amperage draw of the system.

10/24=.42A at 24v.
10/12=.84A at 12v.

IT DRAWS LESS CURRENT AT HIGHER VOLTAGES. THAT IS THE WAY YOUR "THEORETICAL ELECTRICITY LEVEL" WORKS. IT'S A FACT, AND YOU DON'T HAVE A CLUE WHAT YOU'RE TALKING ABOUT.

When you said all the components draw the same power regardless of the voltage, you meant to say current, but you said power. Incidentally, this mistake caused you to make a correct statement. They DO use the same POWER (WATTS) no matter WHAT voltage they use within their ranges.

Say the RCP uses 2W, who knows what it really uses, but we'll go with 2.

At 12v, 2W is .17 amps.
At 24v, 2W is .083 amps.

THEY DRAW DIFFERENT AMOUNTS OF CURRENT BASED ON THE VOLTAGE.

Now, back to your batteries.

So you have a 5000 mAh 12v battery and an n64 that draws 10W.
That translates to .84 amps.
That's 5.95 hours of battery life.

So you have a 3500 mAh 24v battery and an n64 that draws 10W.
That translates to .42 amps.
That's 12 hours of battery life.

YOU ARE WRONG.

well thank you for educating me, in a very mature way I might add, about electronics. I was misinformed by someone in another thread I started asking about this very thing.
