So my Finevu CR300HD and CR500HD battery went dead. Thatz the normal thing for Finevu car cameras with lithium polymer batteries. After reading dashcam forum on how others replace their battery, I going to replace mine my way. I was thinking, since the lithium polymer will be dead in one year's time, why not just solder a connect and replace the battery externally. Much easier than open up the camera again. So my journey starts : Forum read was here : https://dashcamtalk.com/forum/threads/problem-with-the-finevu-cr-300hd-internal-battery.1083/ Detailed instructions of how to strip the camera here : http://www.blackboxmycar.com/blogs/news/10846777-battery-replacement-instruction I opened up mine as per above instructions. Remove the battery, de-solder the circuit board from the battery and solder the JST connector wires. Using my dremel, I drilled a nice clean hole thru the two casings.
