...don´t know how could this be... The standard setting is min 3,09V per Cell under Power !!! In Idle Mode this shoud be more. I think this Lipo is gone and the cells are damaged... I use a Hcigar VT200 and my Boxmod has exactly the same symtoms. I used "USB recovery charge" to reactivate my Lipo Cells - now my Box is still working. But i can observe that my display does not going to sleep. It switches permanently between Idle and Charching maybe 5 times per minute!!! Mode (the box is not USB connected). And the Display is always on. I think this permantent switching is the problem and this slowly unloading of the cells will not be noticed by the chipset. Firmware Bug? I use only the latest official SW/FW - no beta.
