As some of you have read, I'm trying to run my Bafang geared brushless motor without shredding the gears, until a more robust (metal?) gear solution arrives. I'm on my last clean set of gears and have racked up ~50km without disaster, running at 36v nominal (lifepo4).
I'm getting 25-30km/hr on level ground with light peddling. Peddling and accelerating off a stop light draws 15-20A and gets me up to ~20km/hr reasonably quick. On hills, where 15-20A is sustained for more then a few seconds, I can hear the gears straining and have to pedal harder to lower the load on them. I'm obviously a bit gear striping paranoid.
My question is, by limiting current on the Cycle Analyst with my 36-72v 35A Crystalyte Analogue controller, how will the bike behave differently at:
* 36v 20A max limited
* 72v 10a max limited
With the latter, I know I should gain some top speed which I want, but will I lose acceleration off the line? The power is obviously the same but I regularly hear people say "voltage is speed, current is thrust".
Does anyone have an explanation or predictions?
Cheers!
