Just installed and tested the battery on my e-bike. The bike original battery is 7.8A and fully charged gives me around 10/11 Km, the Liitokala "12Ah" fully charged gives me 12/13km (tested on the same day, same weight, same roads). So I guess the battery is around around 9Ah! You get what you pay for! If you need 12Ah get 2 of those or maybe just get a better brand!
thank you
