Had my C1D2 plugged into usb for a couple days with a MXJO 26650. Went to take it off the usb and the device wouldn't respond. Removed the battery and plugged it into my charger to see if it wasn't charging for some reason and my XTAR VC4 wouldn't read it. I assumed it had just silently and thankfully safely drained it too low without causing any venting or leaking. Board seems to be toasted. Won't respond with any 26650 or any 18650 in the adapter. And plugging it in to a PC it never shows in device manager. I had the battery out of the mod for a week while I've been working with the retailer to get a replacement. And, I just inserted the battery into my charger and it's reading full at 4.2v. I'm assuming the xtar won't read above a certain voltage, and the cell finally settled down a bit to 4.2v. Has anyone else had any experience with the DNA75 or 200 overcharging batteries?
