Since my EVO was upgraded to V1.5.8, the first battery failure began to occur. After the next 3 months, all of my batteries showed battery damage warnings. I am using charging hub for charging. I have been using all the versions before V1.5.8 without any problems, only after upgrading v 1.5.8, it started until all the batteries showed damage. And also I found my battery will not automatically discharge since I upgraded to 1.5.8. Although I have set it to automatically discharge after 3 days, the battery is still fully charged after the past week.I found that starting from v1.3.3.25, the battery firmware has been updated. I tried to downgrade the EVO 1 and downgrade one of the damaged batteries to the previous battery firmware version. But unfortunately it has no effect. I have reason to believe that the latest V1.5.8 version may have some changes that may accelerate the aging of the battery or have bugs. Now I don't have any batteries to use, and I am very sad. Each of my batteries has been used about 30 times, and I don’t want to buy it again. Does anyone know how to replace the cells of the EVO1 battery? How to disassemble, thank you
