True Blue Offers TB44 Lithium-ion Battery
The True Blue lithium-ion battery offers triple the battery power of a nicad and a significant weight advantage.

Lead-acid then nickel-cadmium have been aviation standards when it came to battery technology. But that is changing. Modern aircraft are being equipped with lithium-ion technology, not only for instrument backup systems but also for main-ship battery applications.

While this may worry some pilots and aircraft operators, it shouldn’t be cause for concern. The lithium-ion technology used for aircraft today is far more stable than any of the technologies found in mobile devices or laptops. And it is getting better every day.
