Enstrom has expanded its relationship with Airwolf Aerospace, adding an STC for the installation of True Blue Power TB17 lithium-ion batteries. This option will be available for all Enstrom 480B model helicopters.

Airwolf Aerospace has acted as a trusted, long-time supplier for Enstrom, providing the main rotor tension torsion straps for Enstrom's 280FX, F28-F and 480B helicopters.

These TSO-certified batteries boast field-proven superiority over competitors' products. With up to 63 per cent less weight than a traditional helicopter battery, customers can increase their useful load. 480B pilots can expect faster, cooler engine starts with a higher voltage for powerful starts. An automatic, built-in battery heater can keep Enstrom owners flying, even in bitterly cold weather.

The True Blue Power TB17 has an eight year average battery life and a two year maintenance cycle; customers can spend less time in the shop and more time in the air.
