TB17 by True Blue Power, a division of Mid-Continent Instrument, offers substantial weight savings, improved starter performance and longer life.
The TB17 battery weighs 16 lb, which is significantly lighter than the R44’s standard battery (29.5 lb). Lithium-ion chemistry holds a higher charge voltage and provides a more constant discharge rate than lead-acid, delivering consistent, more reliable starts. The battery’s internal heater enhances functionality in cold temperatures as low as -40°C. Typical battery life is 8 years with minimal required maintenance (visual inspection and capacity check) every 2 years.
The TB17 battery passed rigorous manufacturer and FAA tests to ensure safety. A cockpit indicator warns the pilot if a battery fault is detected. During fault conditions, the battery automatically takes itself off-line. 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.
