What snoobler said with clarification. The cerbo has internal storage and doesn't even need a SD card. It will continue to log data and then upload when connection is available.
What you see on the touchscreen is the exact screen you can see on the LOCAL LAN from a phone/tablet/computer...
FYI I use a cerbo to monitor my victron devices and with the internet connection in the trailer it uploads everything and is controllable remotely.
I opted not for the display as I can pull up everything on my phone or tablet from wherever I am.
The reason you want your inverter or mppt to control its cutoff is because if you allow the BMS to handle all cutoffs you will lose power to everything. Better to have the attached devices shut themselves down as opposed to the battery killing everything.
I have two of those same BMS's (ordered two so I would have a spare) and they did act a little wonky UNLESS the B- side was connected to the battery and the cell leads. In other words it had to all be connected for the bluetooth to operate without oddities.
I did make sure all the settings...
Oh I don't disagree that everyone's spike will look different, however the spike will be there as you hit the knees. If you have the ability to see that spike it makes it easier to dial in the settings.
I was curious of the math on this pissing contest so I ran some quick numbers guessing on the cycles for the 40-80 vs the 20-80 range.
So on a 560ah pack if you limited your usage to 40-80% to get another 3000 cycles out of it you would gain an extra 16 months of daily usage out of the cells...
Also to answer your question about victron settings. I have a 560ah 12v setup of the same cells. My system is connected to the VRM and as such I have an immense amount of data so far on these cells over the last 3 months.
Your absorption settings are too high for the cells. See the attached...
