    With electric vehicles we gotta keep some things in min… Slow charging times are better. Its chemical to chemical energy transfer. Imagine using up all your gas in 1 hr, your car would be super inefficient because it would be flying at 200 or 300mph. Similarly for charging, slow is more efficient. Lower ESR values allow you to charge faster, but also increases your standard 15 minute per series cell charge efficiency.
