Note that topbalancing this precise is totally unnecesary and most likely more harmful than good considering having cells stay at high voltage with 99.9% SoC
This pack is a 560ah 12v lifepo4 being balanced with 35mA only between 3.644-3.650v.
Cell difference is 1mV or less at 99.9 SoC or more.
I have an electric ass heater drawing around 4 amps connected before the bms and a bench power supply connected after the bms set at 13.6V limit.
That means the bms can balance while basically no current is leaving the battery. The bms can see the current coming in from the bench power supply but cant see the current leaving the battery to my electric ass warmer thus circumventing the "only balance when charging" rule the bms has.
At 10 sec mark in video my electric heater turns off.
At 3 min it is on
At 4 min it is off again
The bench power supply holds the cells at 3.650v with 0.1 amp which the bms cant display because it has a limit that wont allow it to display 2 amp current or less
Like watching paint dry but im sure for those who got OCD about this stuff it is a treat
