Yes, I absolutely agree. I found sunshine ego to be very knowledgable and began the road to recovery of understanding. At least a lot of things here and there were others as well. Everybody’s helped so much. I’m very happy about that.

I REALLY appreciate your input RV8R
Ok then
;I am going to post my opinions here for you ,,, I am a hobbyist not a professional & consider myself a novice ( but that does not mean I have zero experience or knowledge ).
So I am not being critical here, but want to shed some light on when I see;
I have seen switches that look like these that have burnt or melted on the Internet. I don’t buy these style of switches and have no experience with them because I’d buy blue sea switches. And usually 4 way switches ( they are $5 more than a 2 way & can be very useful );

350 Amps continuous rating for inboard gasoline or diesel engines.

There is a big difference in “switching” AC & DC ,,, This video demonstrates the differences very well;

These questions ?
The short answers is “I don’t know” & there are more knowledgeable members on the forum that would be able to give you a proper answer. I will leave that setup & monitoring suggestions to those that are experienced at it. My Vans & Cabin so far have used AGMs & no BMS.
My guess is yes ,,, If you hit the charge point of cell balancing for the required time & reset the BMS, I think then at that point in time the BMS is recalibrated.
Further it is my understanding you have been “under charging” your LFP battery & LFP like to be stored below 80% SOC ( opposite to AGM ), so if you are concerned about damage over the 5 months operating ,,, I do not think you have an issue.
The testing for “loss of capacity” can be performed, & someone knowledgeable can walk you thru that, but I don’t think from what I have read on this thread you have any issue.
It is disheartening that “Alberta Lithium” was not very helpful for you. I’m assuming they want to sell batteries and equipment and restrict their involvement with customers past the sales. I understand, but I was expecting a better detailed performance spec or a manual at least “on-Line”.
I have purchased Rolls AGMs. Rolls is another Canadian battery company. Here is their manual & specs ,,, much different than Alberta Lithium as an example;

Yes, very poor showing and they try to make it sound like everybody just thinks they’re awesome and have amazing customer service but it’s all about sales and they are not helpful at all with troubleshooting or newbies like me looking for solid answers about everything and they get quite nasty actually and it’s been very heartbreaking.

Yes;
Blue circle; What is the make / model ?
Red circle; Rover MPPT Make / Model?
Yellow circle; AC to DC Charger ? Make / Model ?
So I can spend time searching the internet & the “Rover” is an easy one to “Sleuth” or You can help by listing the make & model of your electrical equipment.
I can clearly see the Inverter
.You should have manuals on all this equipment ,,, or produce performance specifications in the very least.

I’m heading off the forum momentarily, but will leave you with some things to consider in regards to your system;
Fuses
Switches
Buses
Positive connections safety covers
Product identification ( Make / Model ) get manuals & product performance specs (PV)
Possibly an electrical schematic
Load Chart or “Energy Audit”
I know you are dealing with learning LFP / BMS / Charging right now, so will leave you with those ideas for your future consideration.
Good Luck with it All !!

Thank you RV8R
I very much appreciate your helpful feedback
You are very welcome !!
30 amp MPPT charger
60 amp “Alberta Lithium” charger
,,, made in China sticker 
,,, Please get a manual for this, or a link to the manual & post it here ( I know everything these days is made in China ,,, It really isn’t that that bothers me it is the seemingly lack of a manuals online );
IMO, caring about charging batteries is pretty important to the health of the batteries. For me, I want to unsure my chargers & settings are matched to the battery manufacturer’s charging specifications.
& I can’t do that if I don’t have the battery manual ( in general ) ,,, thus far I am not impressed with “Alberta Lithium” ,,, they seem short on details ,,, nice snowmobile photo though
