Lithium conversion is not for the risk adverse. Some of those batteries can be purchased with a 3 year full replacement/refund warranty thru Amazon/Asurion for about $170.
I built a 150ah pack using EVE cells about 4 years ago when I purchased the cells for $100 each. I am considering building a 314ah pack using EVE or CATL cells now that the price is under $100/cell but I really don't need the 120 mile range. It is better to build your own pack to make sure of quality/grade-A cells and robust BMS but I don't recommend doing it without skillset nor will I build a pack for others. I am also risk adverse
