Battery runtime is one thing, overall battery capacity is a whole other thing. Why? Because when you are riding multiple days charging time or even the possibility of charging through a dynamo at all becomes relevant. Case in point: What good is a runtime of 30 hours on the Ace possibly for me if I need 120 hours and the Ace’s has a giant battery and a - corresponding to its screen size - equivalent gigantic power consumption.
Long story, short question: Can anyone tell me what the battery capacity for Bolt v3, Roam v3 (and possibly Ace, although that device does not interest me currently) is?
