@treenutter I’m by no means experienced after only 4 rides but I’ll share nonetheless, for what It’s worth.
I posted about voltage cutoff in my build thread. If you look at my discharge curves (or any lipo curves on the net for that matter) you’ll see the voltage drop steeply past 3.6V per cell.
So on my last ride I had the voltage cutoff set to 3.6V x 12 and I quit riding as soon as I felt the power drop. Worked pefectly, my charger told me all cells were perfectly at 3.6V and the 5000mAh Zippy’s soaked up about 5200mAh on my charger to get back to 4.2V.
Unfortunately discharge curves don’t tell you how much the cell voltage sags under heavy load. Because I had my cutoff set too high initially, I was hitting it even with charged Lipo’s just by accelerating fast, just because my lipo’s couldn’t keep up. I think.
There are settings for both motor and battery current limits. As I’m using the R-SPEC’s I left the default motor settings alone, and set the battery current limit to match what people were telling me my lipo’s would be capable of and just above the max current my wattmeter was reading.
Hope this helps.
