We had a good chance to compare 3 bikes during the 2nd Vectrix meeting in Barcelona.
All 3 have started in the same place, and have made the same trip at same speed.
At Estela Hotel's recharging point, Aleix's bike charged faster than the other two, in other words, the battery has less capacity. The bike has only 700 km but it is used everyday. It is a 2nd hand bike which has been carelessly stored for a long period of time. I'm suspecting that the battery is damaged...
Please have a look at the picture comparing displays: (I can't post hi-resolution pictures here)
