@Ari
Have you ever seen next problem:
I have darkknight in my posession.
The battery was fully discharged, during watching the movie and projector automatically switched off. After plugging it in from the outlet: The projector starts up, the fan is working, the remote control responds, autofocus works -when i moving projector, the audio mod also works well, but the projector does not project the image.
There is no image at all...

Thanks for the link but i didnt found answer..
I have cc aurora dark knight in my possession, I tried to charge battery over the night, but indicator on the screen showing that battery still charging, even charger was plugged off.

Battery life during watching max 30 min. I got an answer from service center - that probably problem in power controller and there is no possibility for 18650 batterys repacking. Even after battery repacking service center doesnt have software for controller reprogramming.
Does any body has any suggestion or solution?
Thanks in advance
