DHC-8100 / 200 / 300 Series
Certified Lithium-ion Aircraft Battery Upgrade
DHC-8-300
The TB44 Certified Lithium-ion Aircraft Battery features
the most sophisticated lithium-ion chemistry available,
providing DHC-8 operators with an unmatched advantage
of increased power, reduced weight, extended useful life,
2-year maintenance intervals, lower direct operating cost
and higher profit potential.
The intelligent battery system’s Nanophosphate®
lithium-ion cells provide 3x the energy per kilogram
and are rated up to 10,000 cycles, per cell. This results
in a battery solution that is 56 – 80 pounds (35 – 43%)
lighter than NiCad and lead-acid alternatives.
Safety is addressed on multiple levels, including chemistry,
cell design, containment and the integration of electronic
protections. The TB44 is a ‘smart pack’ engineered to
protect against overcharge, over-discharge, over-current,
short circuit, over-temperature and under-temperature.
Ideal for high utilization and rugged environments, the
TB44 starts the aircraft’s engine quickly and offers superior
hot and cold weather performance.
