The TB44 Certified Lithium-ion Aircraft Battery from True Blue Power features the most sophisticated lithium-ion chemistry available, providing Cessna Caravan® operators with an unmatched advantage of increased power, reduced weight, extended useful life, 2-year maintenance intervals, lower direct operating cost and higher profit potential. The intelligent battery system’s Nanophosphate® lithium-ion cells provide 3x the energy per kilogram and are rated up to 10,000 cycles, per cell. This results in a battery that is 29 – 32 pounds (36 – 38%) lighter than lead-acid and NiCad alternatives. Safety is addressed on multiple levels, including chemistry, cell design, containment and the integration of electronic protections. The TB44 is a ‘smart pack’ engineered to protect against overcharge, over-discharge, over-current, short circuit, over-temperature and under-temperature. Ideal for high utilization and rugged environments, the TB44 starts the aircraft’s engine quickly and offers superior hot and cold weather performance. A Supplemental Type Certificate (STC) approves installation of the TB44 on all Cessna Caravan® 208 and 208B series aircraft; engine types PT6A-114, -114A, -140, -42A.
