Small update which folks might find helpful. I have 5 of these batteries in parallel, and they work very well. I did notice that I was seeing some strange issues with one of the batteries occasionally where it would significantly discharge more than the others, according to its display - I'd wake up some mornings after an overnight grid charge and see 4 of the batteries charged to around 90% SoC, but one lagging behind (~50%). I assumed perhaps I needed to do some balancing, so I bought a small 60v DC charger to top them up but noticed something odd - the laggard battery at 50% would charge up to 100% very quickly (too quick for the state of charge to make sense), almost as though it was displaying the wrong SoC.
I was scratching my head at this for a while, but I found a solution this week with my Solis 6kW inverter. I updated the battery settings from user-defined (similar to Vito's in post 1), to instead use "Pylon LV" as a battery type, as I recall from the manual that the batteries were compatible with Pylontech in some way.. To my surprise, after the settings update, the inverter was showing the correct SoC, but more interestingly, the laggard battery updated its SoC on its display to something more accurate. It showed 60% SoC before the setting change; then it jumped to 90% (similar to the other batteries) after the setting on the inverter was updated. Since altering this setting I've had 0 alerts, and the delta between SoC on the batteries has been less than 5% at any given time.

if you want to know more details. just let me know.
