Lithium-ion Aircraft Battery
Technical Description
The new Gen5 TB50 Lithium-ion Aircraft Battery is a same-size replacement for the industry standard 44 amp-hour battery, while offering more power, less weight and zero maintenance. The TSO-certified TB50 from True Blue Power lasts 8 years and features an automatic, built-in heater. This allows your aircraft to outperform all others in extreme temperatures, from -40°C to +70°C.
