More or less, but you also need to take in to account the Peukert Effect [1] and the discharge rate that you plan on using the batteries at.
At high C rates the 160ah lithium batters would probably still have _more_ usable energy then 400ah of flooded Lead batteries. Maybe slightly less then a
AGM battery that can go to 60% discharge[2]. But all really depends on you discharge rate.

it's a question.... if one has a 400ah battery bank of lead acid batteries and one can only pull about 40% from them then one is only getting 160ah of actual work right.... wouldn't the equivalent batteries of a lithium type only need to be 160ah to get that same amount of useful work because lithium batteries can be completely discharged?
