6V - 12V ?

[buki]

V = I * R

Voltage is equal to Current times Resistance.

This is Ohm's Law.

Since the resistance is pretty much fixed for the bait tank, the only variable is the voltage and current. The voltage is directly proportional to current. This means that if the voltage goes up, the current goes up. If the voltage goes down, the current goes down.

I trust you all are doing what you say but before I buy a 6v Batt to get more time with less waight, I'd like to know some more facts. Can anyone offer up some technical facts to set me straight?
