You never know whos cells are in the video. I maybe a small Ping pack. As I remember most of the Pings are only rated for 1c to 1.5c. Bob
Bob, your point is driven home by the data I'm seeing in the logs on my CellLog 8. (Although the new lower priced model of the CellLog is fine, I'm glad I have the version that logs. You see the performance of each cell under load.) The area I ride is hilly; I'm in the far northern US Rockies, west of Glacier National Park. What I'm seeing when riding a steep hill (say 15% grade and a climb of 154 ft in less than a mile) is power in individual cells declining as low as 3.03 then rebounding back up to 3.302 once I've cleared the hill. When going up hills, I don't depress the throttle too much and I pedal in low gear to assist the motor. That said, climbing steep hills with any motor assist is going to eat up a fair amount of energy (flat landers definitely get better battery performance and a longer battery life). However, my knees are extremely grateful for the assistance and my primary purpose for getting my bike electrified was to have power assist to tackle the hills around here.
