Lithium Batteries

So I am still trying to learn about many different things - lol not sure that I don’t just keep digging myself deeper!

I asked a question in another port and they asked me if my batteries had “internal heating” … sadly, I didn’t even know that until the question was asked.

Are there any posts or sources that summarize batteries in general?
I recently upgraded my system from LeadAcid batteries to Lithium. Admittedly, I probably just went on cost mainly and I purchased 3 Renogy 100 ah batteries (w/o BT, I added the module) and 2 Renogy 200ah batteries (w/ BT).
They seem to be fine but as I said purchased because of price. The 100’s were approx $400 or so and the 200’s were just under $1000.

Now that I am doing some more research esp regarding some issues with some pretty fast discharge in cold weather I was wondering if others could share personal experience or research sources?
For example, I saw this Victron 200 ah battery and it cost almost twice as much. Are they worth it?
