I have seen that e-bike batteries may drain by itself. Batteries charged to 40%, which is a good practice to extend lifetime, were completely discharged after one month. So I opened a battery and tried to investigate what happened. By doing measurements at the electronics, I found out that the cause of the discharge is the fuel gauge, which had a quiescent current of 6mA. This will take just one month to discharge a battery which is charged to 4Ah. See more here:
