OUR RV GETS A SOLAR UPGRADE. BATTERY BALANCING CONFUSION. PART 0.5

a preliminary view at our sungold 24v Inverter install and eco worthy 150ah lifepo4 lithium batteries and getting them to balance. are cheap Amazon batteries worth it?

The charge voltage curve of LFP batteries is very flat, current passing through each battery would be very small when you have them in parallel. would take a very long time for the balancing process to be done passively. this is also why you cant measure their state of charge using just the voltage.
as youve mentioned, each battery needs to be charged individually with a charger and companies recommend fully charging LFP batteries through the grid/generator to maintain voltage for x amount of time after current drops off before using them "offgrid".
11.5kwh total battery bank power would run those window units(~550w) with the compressor permanently on for ~20 hours
i have a 10.2kwh battery bank but also have a 24/7 300w load so i can only use the eco feature that turns off the fan(~60w) shortly after the compressor to get me 2 nights(enough solar through the day to cover the load but not gain charge). i do use a seprate oscillating fan that uses less power(~25w) to keep the air ciculating.

Now that I have the balancer they stay pretty dead even all the time now. 0.1% to 0.2% deviation according to the shunt
