Way back there were a few issues resulting in shutdowns or reboots. Thought those days were long behind me, but the last few weeks my controller constantly shuts down. Thought I’d share the reason in case others are experiencing this. I thought it was odd my controller would only charge at 1.5w. Got me thinking I may have a pair of bad cells with extremely high internal resistance. So basically when I’d start streaming, as the current demand increases a good portion of voltage was being drop within the bad cells. Kind of explains why it would only shut down when the battery level was below 70%. New cell fixed it. All good now!
