I was reading through some threads on phase/battery current.. the general consensus is to keep phase current about 2.5x battery current. And with a block time of 1 second, this is now setups come "stock".
Then I also read, specifically from mwkeefer, that lowering the phase current to just 1.5x battery current will increase the top speed a little bit.. has this been confirmed and if so, why would this be the case?
On a very elementary understanding, my belief is that if you are moving slower than what the motor wants to be moving at, the controller will increase phase current at the expense of voltage. So if you have a 1:1 ratio of phase:battery, even if you were traveling up a hill, your motor would see the same amps as battery current. With 2.5:1 ratio, it will multiply the phase amps and will slowly taper off to battery current once you reach the speed the motor wants to be in.
So now my question is, if I want an efficient setup, in the sense that I want more range, I can either play with this setting to get the lowest battery amps with the highest speed, or travel slower, which I'd rather not do.. what will give me say 25mph, using the least battery current.. a high phase/battery current ratio, or a low one?
