JCG wrote:As for the bike, the consideration here is to use acceleration bursts and soaking as much as possible back while braking. A 500 W acceleration busrt for 5 seconds only uses 2.5 kJ of the 84 kJ stored in the twin module series. The trick is getting that 2.5 kJ back by braking or pedaling against generator resistance... should be fun to try.

With over 1 million duty cycles on the large cells (the type in my modules), the caps will easily outlast the motor and everything else on the bike, the bike itself, and the next one, etc. Li ion cells are lucky to get 1000 duty cycles before they lose most of their capacity.

The pack seems very well built and should handle a tumble but what kind of uhm.. looking for the right word here.. " event " ? can one expect from a fully loaded charge taking a fall and opening up .. ?
