The FAA has issued Supplemental Type Certificates (STCs) for True Blue Power’s TB44 (46-amp hour) lithium-ion batteries on Cessna Model 208 and 208B Caravans.
According to company officials, operational and performance improvements include:
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.
