On lipos 50% capacity is about 3.85 volts per cell, 12S = 46.2V. Controller Low voltage cutoff is usually 42V; 42/12S = 3.5V per cell, which is correct for lipo.terminus wrote:I'm not real good at math but aren't those lipo packs 22V? How does that equal 46V when you build the pack? And is there a way to change the LVC on those cheapo motor kits so it doesn't cut off at 46v, or 44v, or whatever it is?
Do you notice any kind of stress / overheat from going up those hills?Hodie Doe wrote:As far as the yescom rear hub motor and hills i have 793 miles 40hrs 18mins average 19.73 MPH and the hills range from 4% grade 2 23% a few steeper but i do not run those routes often . 0n 4% to 10 it maintains 22 to 18 mph steeper hills the speed drops but most with minimal peddling you can maintain 15 to 20 MPH .
