[QUOTE="fly_marlin, post: 8412488, member: 660781"] Hope I do my math right: 1. Let's say, roughly, you're at 14v running the 3kW amp at 1 ohm at 80% efficiency. 3000/14/0.8=267A draw. 2. XS 3100 has a capacity of 110ah. Peukert's Law is then used as follows: t=(110)/(267^1.3)=110/1427=0.077hours=4.6min=4min and 36sec. As you can see, with any voltage drop below 14 and efficiency below 80%, you will see a good decrease in the time before the battery is drained. [/QUOTE]
