Hi there,
Ioniq 5 and Kia EV6 battery packs for sale, several packs available. I think they are ~78 kwh each. 5000€ per pack or NO, delivery to most of EU, IRL & NI and UK. Can split and ship only half of the pack for less. They are essentialy 2x 400v packs in one enclosure. Two halves could possibly be wired in parallel for 78 kwh 400v like has been done with smaller BMW hybrid packs. PM for details.
