King Air 350 Lithium-ion Battery STC Kit | 46 Ah Battery STC Kit | TB44 Lithium-ion Battery
Technical Description
King Air 350 Lithium-ion Battery STC Kit
Reduce your aircraft battery weight by 40% with the TB44 Advanced Lithium-ion Aircraft Battery. Less weight means more passengers, more cargo, more fuel and more design flexibility. The True Blue Power lithium-ion battery is TSO certified, offers 2-year maintenance intervals, and lasts 8 years — 4x longer than lead-acid and NiCad batteries. A built-in heater ensures superior cold weather performance, down to -40°C.
