N2 power consumption, technical question

Post by macey »

Technical question regarding N2 power performance. Hello, I'm running an N2 with a battery pack which has a variety of output voltages between 5 and 20 volts. Can anyone tell me which voltage will give the longest battery life without sacrificing performance? 5v, 8.4v, 9v,12v,16.5 and 20v.. Yes, I know I could trial it myself.๐Ÿ˜ณ๐Ÿ˜‚

First of all, do not connect higher than 18Volt source. Otherwise, you will damage the N2 board,
And the minimum stable working voltage is 7.5 volt.

I think 7.5 ~ 12.5 volt could have slightly higher power conversion efficiency than 12.6~18.0 volt.
But the difference could be very negligible.

Ok, if I run at 8 volt instead of 12 volt, will there be any performance degradation?

Nope. The system performance doesn't depend on the input voltage.

Ok,so if I drop the voltage to 8 volts from 12 , the current drain will either stay the same or go down, right? So, overall, power consumption should reduce, correct?

Nope.
Your N2 consumes about 8 Watt with some very heavy computing CPU/GPU loads without USB devices.
If your PSU output voltage is 8V, the current drain is around 1Amp.
If your PSU output voltage is 12V, the current drain is around 0.7mp.
