I know the lithium iron phosphate batteries are better than the lead acid batteries, so I assume all lithium iron phosphate batteries are deep cycle batteries?, is my assumption correct?

With lithium batteries, you need a BMS (battery management system) either built-in or add-on. The second one has the BMS.

There are some lithium batteries designed for starting, some are deep-cycle. The ones you linked specify they are deep cycle.

The second one has a big warning about charging outside of the parameters it wants. You will need to pick your solar charge controller based on this requirement. This probably means a charge controller where all the stages are programmable.

Will these controllers work with the second battery do you think?...

I believe all lithium batteries are deep cycle.
