With winds 18kph and gusting to 28kph I pedaled fairly steady.
Here are my stats at WOT:
average speed 40kph
max speed 52kph
76.8v nom pack LiFePO4 38120HP 24s1p
What is great is understanding your whole Ebike build.
Pack vs controller vs Hub motor and how each one interacts with the other.
Pack: 76.8v 8ah
Controller: infineon based 72v 40amp shunt
What is interesting about this set up is that at quick take-offs, she will draw some large watts (2800 or so) but only for a short period.
As you pick up speed, she drops right off. Almost self regulating.... it's probably that KV thing that I've read so much about
So my pack draws around 4 to 5C (2400 to 3000 watts) for a short burst then at full speed 1 to 2.5C (600 to 1500 watts).
Now the HP cells I've tested 4.5C for 80% DOD and they hold their nominal voltage or just slightly under.
So I think that my pack is the minimum for a 40amp controller. If I go to a Lyen, I'd think that I would add a few cells to a 30s1p 96v nom
This would give me around 3800 watts max at 5C and maybe a few more kph with the higher voltage....KV thing again
But the important thing to note here...... ORANGEEnter OHM numbers from the back of the controller into the CA DP under the advanced RShunt section
