The Trek E-bike Battery Pack was dead after not used during winter - RustyOx - 30-04-2022
My Trek e-book haven't been used during the winter, and I found it is not able to be turned on.
The Battery Pack was built with Samsung 3345mAH 18650 8A battery about two years ago, now it is completely dead. It
is measured only about 10V (norminal voltage is 40.7V for 11s battery pack) which means only 3 of 11s is working.
Most battery measured at 0V, few measured at negative voltage. The balance board is also burned.
