Changing volts and amps

[boppinbob]

I have a sensor less HS 3540 with a 7240a Crystalyte controller and an APM display. You can change voltages and amp setting on the controller with the APM. I have 4 zippy 5s8Ah packs in series for 72v 40amps, which is what I normally set it to. Today I reduced the voltage to 60v and 30amps. Does that increase the mileage I can get on a charge. I didn't run it long enough to find out. I hope I don't kill the controller testing it like that. It might be that it only reduces the lvc. I had to work today so I didn't test it on the road for long enough to find anything out. Next week I'll give it a better testing unless someone in this forum thinks I'm harming the controller or motor. Regards, Bob Pate

It seems to me that it'd reduce the LVC so you could pull your pack down too far. It should slightly reduce your top speed though, so you should get a good distance farther even if you stop at the normal LVC...? I'm not familiar w/ that setup..just guessing.

I believe the volts that you program in the apm sets the fuel bar, so the little fuel bar levels will show when you are running out of battery. you do not want to set the LVC lower than what is recomended for you R/C lipo- that can be dangerous. By setting the amperage lower to the 30amps, theoretically will increase your mileage some. less amps drawn= more amphour availible.

The only way you will increase range from the same pack is to slow down. Decrease your watthours per mile, get more miles out of the same number of wh.
