Re: Running Two Batteries
LED's won't make a difference.
Something that would make a difference would be an extra CIM motor, so I'll use that for comparison.

A single CIM motor might be expected to draw about 40 amps at 12 volts during normal usage. That's 480 watts.

If you had one really bright led, LEDs are about 90 lumens per watt, so 480 watts is 43,200 lumens, which is insanely bright. A "typical" home lightbulb is about 700 lumens. 50,000 lumens is the intensity of a Nightsun, the searchlight that gets mounted to Coast Guard helicopters. If you look into one, you can go blind very quickly.

If you had a bunch of normal LED's. A high output LED uses 20 mA at 5 V or 0.1 watts. 480 watts is around 4,800 led lights, way more than you'll ever see on a FRC robot.
