The LG batteries in GM EVs have already proven defective.
The big $ battery plants Ford is building along I-65 in KY and TN will be a huge bet to use an unproven South Korean technology.
Tesla has had relatively good on road longevity with the Panasonic (actually Sanyo) Li batteries
but is now switching to a case size that creates smaller but denser cells.
What Li cells will Still-Aint-US use in the Ram pickup?
(Do not rule out that something other than Li will pop up and prove to be the best battery)
