Some sites, and youtube videos are claiming it is possible Tesla may use Lithium Iron on the lower range Cybertruck's.
Personally I'm OK with this as I think Lithium Iron batteries charge from 100% to 0% without damage and have more lifetime cycles. Getting 100% of 300 miles vs 20% off the top and bottom (40%) of 500 miles, makes the 300 mile dual motor CT if it has Lithium Iron more of a net positive. Is there something I'm missing? 60% of 500 is 300. Keeping between 80% and 20% or going to 100% and down to near zero gives comparable daily mileage.
The 500 mile CT may be best for long range driving or hauling.
