The R44s aerodynamic fuselage optimizes airspeed and fuel. R44s have a two-bladed rotor system, T-bar cyclic and the latest in Robinson technology including streamlined instrument panels and crashworthy bladder fuel tanks. Built-in circuitry prevents overcharge and/or overheating, and the TB17’s advanced Nonophoshate® chemistry is much less susceptible to thermal runaway than many other Lithium-ion batteries. The four-seat Robinson R44 Raven II helicopter is a high performing, reliable machine that is easy to maintain. During fault conditions, the battery automatically takes itself off-line. A cockpit indicator warns the pilot if a battery fault is detected. The TB17 battery passed rigorous manufacturer and FAA tests to ensure safety. Typical battery life is 8 years with minimal required maintenance (visual inspection and capacity check) every 2 years. The battery’s internal heater enhances functionality in cold temperatures as low as -40☌. Lithium-ion chemistry holds a higher charge voltage and provides a more constant discharge rate than lead-acid, delivering consistent, more reliable starts. The TB17 battery weighs 16 lb, which is significantly lighter than the R44’s standard battery (29.5 lb).
