I just followed your hand movements. I tried to open mine with very little success but I will keep trying. You measured the voltage on each battery and they seemed to be OK. Do you change them as a preventative measure and secondly does the motherboard have to changed because of an error flagged by the MCU?Great work and thanks
You can't reuse the charging board. Once the MCU detects an error (this is when the battery refuses to work, before disassembling), it locks down the MOSFET permanently, effectively preventing both charging and discharging. Same goes to modern laptop batteries.

@@iamkhtray You really think these companies haven't thought about it, or are they stupid enough to let you do it? Not a chance. The batteries in most modern electronics are locked down in factory. You will never be able to swap the cells so that you have to buy new ones from the original company.

@@chounoki thank you, how about swapping the cell one by one? my current situation on SV09 is that I was able to turn it on for one min and ten seconds and it stopped and flash the amber light one time and ten times the blue light. When I charge it is in steady blue light. I was thinking of swapping with Samsung 18650 cells, not sure if it would work or not. thank you
