Hey all , my vt200 is not charging fully atm (maxed out at 79%) . USB current is hovering around 0.05-0.06 Amp . Cell 1 (4.20v) Cell 2 (4.02v) Cell 3 (4.20v) . On the device monitor , Cell 2 sometimes has an error flash . I suspect cell 2 is going bad . The battery level seems to drop slowly the longer i charge (now at 75%). Is there anything i can do to rectify this without changing the lipos ? . Thanks All this happened after I updated to sp3. UPDATE : After hard reboot , battery jumped up to 80% . Weird
