I have a Bosch powered bike with a piggyback frame mount extender being installed. I intend to carry either a spare frame out or a Powertube for very long days with lots of climbing.
Has Bosch published information about how the logic handles swapped batteries in piggyback configurations? I've heard that the motor normally draws from both batteries simultaneously. If I run the bike down to 10% charge and then swap out one of the two batteries, will it continue drawing from the batteries simultaneously or will it draw solely from the fresher battery until it the combined charge drops to 10% again?
Likewise, if I charge both batteries either fully or partway and swap in a near-empty battery, will it charge only the emptier battery solely until it catches up to the fuller battery? If the fuller battery is 100%, can it still "fast charge" the empty battery?
