Not very many people are even using LTO batteries at this point. Almost everything would have to be made custom which means tha answer would be... "it depends"
You can buy LTO batteries 2nd hand though, sometimes. You can also buy LTO batteries that are second hand when you purchased thrm new.

from the wikipedia article
Zinc Bromine Drawbacks
The need to be fully discharged every few days to prevent zinc dendrites that can puncture the separator.[2]
The LTO cells have almost no maintenance issues have a lifetime of cycles.
LTO cost at 20,000 cycles 88 wh per cell $60.00 per cell is $0.034 per Kwh over its lifetime
Battleborn Lithium 10,000 cycles at 1200wh per cycle $900 dolar per battery cost =$.075 per kwh over its lifetime
I couldnt find anything other than $.43 cents per KWH from google search of Zinc Bromine
Zinc Bromine Drawbacks
The need to be fully discharged every few days to prevent zinc dendrites that can puncture the separator.[2]
- The need every 1–4 cycles to short the terminals across a low-impedance shunt while running the electrolyte pump, to fully remove zinc from battery plates.[2]
- Low areal power (<0.2 W/cm2) during both charge and discharge, which translates into a high cost of power

What Craig said. with 2.2 volts the density per weight is a lot less then LIPO. EVs are still trying to reach ranges that are acceptable to people and that means as power dense as possible. With new improvements in Lithium ion technology and the fact that most people don't completely discharge their car on each cycle means that lithium ion is good enough for cars. Most people don't want to drive the same car for 80 years anyways so nobody is complaining. Battery tech is improving by the day though.
