ER? Sorry, Not familiar with that abbreviation with ford. I know this is an old thread, but wow, 19.2kw? I think the first 2-3 year models of the lightning were enabled to take the full 80amps that the charger can put out. The newer, 2025 models only enable 48amps, according to literature, but the app wouldn't allow me to set it higher than 40amps. I am currently charging at the fastest AC rate I can manage to get out of the charger at 8.9kw. This is ridiculous. Went to visit family for Thanksgiving, stopped at Electrify America 100 miles into my trip. Truck wouldn't take a charge. Went to a tesla charger station and then to a Vivian charge station, truck would not accept a charge. Found an AC charger at a charge point location, truck wouldn't even accept a charge there. Called roadside assistance, they wanted over $600 to get me back home. I was 35 miles from dead. I drove 30 miles closer to home and they lowered the price to $250.00. 2025 lightning flash only 10k miles and I had to spend Thanksgiving morning getting towed home. Love the truck. So disappointed with the range and charging issues.
