Did a capacity test today... and I'm quite impressed by my pack.
I did 66 km at around 35-40 kph, and a lot of start and stop. So a lot of acceleration.
I use it until 58V under load:
I noticed that under 61V, the pack voltage drop really quickly.
And on my cycle analyst, it says I used 1450wh
My cycle analyst is probably mis-calibrated, because it would otherwise mean that my pack has over 22AH capacity. I did 66 km at 35-40 kph with good acceleration, so my bike used at least 15 wh/km and my pack has at least 1000wh even if miscalibrated.
It was a bit warm after the ride, but I think I'm going to be happy with my pack.
