The last time I checked, battery packs are measured in capacity, not miles. Cars have a mileage/range rating. What's important is the capacity and weight of the battery, and then the efficiency of the vehicle it is installed into.
The Shenxing Plus battery adds 372 miles in 10 minutes of charging and is built with affordable LFP cell chemistry. CATL also budged on solid-state batteries and will start their mass production.
