Increased power — three times the energy per kilogram;

Extended useful battery life — more than double lead-acid and NiCad alternatives;

Rapid recharge — back-to-back engine starts;

Cooler and cleaner engine starts — less wear and extended life on engine components;

Superior high temperature and cold weather performance ;(-40°C/-40°F to +70°C/158°F)

Reduced empty weight and increased useful load;

Reduced maintenance costs — 50 to 90% less scheduled maintenance;

Reduced direct operating costs — less fuel, less maintenance, less ground personnel, less infrastructure;

Zero carbon emissions — eco-friendly Nanophosphate lithium-ion cell chemistry.
