Hi I have just started building Mi powerwall! Have to say great job with the 'youtube' Mr HB Powerwall, have been inspired with your enthusiasm, great job and now... I have a thought that I would like to throw out there.
'Charging and discharging and internal resistance'...I think I have noticed a corrleation 'probably no surprise' with internal battery resistance and capacity anything above about 170/200 m Ohm's seems to have a low Capacity below 2000mA ???? So with that why not check the resistance first and discard from there. I also ran a test to see the difference in resistance from part charged to fully charged 3.4V ish to 4.17V isn and there was maybe a 10 to 30 m Ohm difference!!.......and now a Question:what size copper sheet are you using for the bus bar that you solder the batteries to?
Keep the great work up Thanks Mi powerWall. :mrgreen:
