Conversion Electric Car(would like to purchase some LiFePO4 Batteies)

I am from a company in Australia currently converting electric vehicles. We have been using the Thunder Sky batteries but the quality haven’t very good and are looking for other options.
Today,i found an manufactory of LiFePO4 Batteries , the link:
