Electrifying trucking will mean sacrificing critical weight for heavy batteries, eating into already-slim margins

• A semi-truck can weigh up to 80,000 pounds. Its battery can take up to a fourth of that weight. 
• An electric long-haul truck in 2030 could be up to 5,328 pounds heavier than a regular diesel truck, experts predict.
• Heavy batteries could eat into trucking's already-slim margins. 

American truck manufacturers like Freightliner and Tesla are already delivering the electric trucks that the industry needs to pivot away from gas engines.
