actually if you watched the video and read the comments.
they were Charging the battery's without a BMS unit which is pretty much a requirement.
and for the comments on cheaping out. those are prolly some of the highest quality cells you can buy period.
this was a charging issue, and for the guy who posts this video, to hide the fact it was getting charge at the time is shameful.
Cheaping out is buying used batteries on ebay or scrapyard from an unknown EV source. Was it just retired because of miles, hours on cells, lower voltage for EV standards or a wrecked from an accident. They could be the best batteries they certainly give a great show when going thermal.
There was no hiding a fact of charging or not. For folks wanting to play with this chemistry of lithium they should know or see what a thermal run away looks like. You did catch the statement they made of using 8 fire extinguishers to just contain it but they could not extinguish the batteries.
Shameful not one bit I'm living fulltime off Lifepo4 chemistry batteries for 31+ months now.
