True Blue Lithium Battery Upgrade STC’d for PC

True Blue Power has received an FAA supplemental type certificate (STC) for installation of its Gen5 TB40 lithium-ion battery on all Pilatus PC-12 models. According to the company, the TB40 upgrade provides pilots with the ability to attempt multiple, repetitive starts while helping to prevent hot starts, costly engine repairs, or extended downtime.

The STC was developed by Finnoff Aviation Products and includes modifications for both single and dual main battery systems on early model PC-12s through the latest PC-12 NGX. Key benefits of the installation include weight savings of 60 percent compared to traditional lead-acid batteries, on-condition maintenance, and an extended eight-year battery life expectancy. With a capacity of 40 amp-hours at 26.4 volts of direct current, the TB40 battery can easily start PT6A-67B/P engines in all climates, from -40 degrees C to 70 degrees C (-40 degrees F to 158 degrees F).

"True Blue Power Gen5 batteries last four times longer than lead-acid and NiCad batteries," said company director of aftermarket sales and support Van Winter. "The reduced maintenance and longer useful life can save PC-12 owners and operators up to $1,200 a year in total maintenance cost with a single battery. The TB40 quickly pays for itself."
