Field notes
The index lets visitors filter by capacity and brand, sort on several measures, and compare up to three units; its charts plot capacity against street price and include price-per-watt-hour and weight measures. The author says the score is formula-based and brands cannot pay for placement. Street prices are described as typical U.S. prices that move, and values marked ≈ remain estimates pending manufacturer confirmation.
