The company now offers lithium-ion batteries for all markets, from Experimental and Homebuilt to the largest Commercial and Defense aircraft.

ORLANDO, Fla. — True Blue Power, the first company in the world to engineer and certify lithium-ion batteries for aviation, introduced two new, main ship batteries at the Aircraft Electronics Association International Convention and Trade Show in Orlando, Florida this week. The certified TB14 (13 amp-hour) and TB28–12V (26 amp-hour) lithium-ion batteries are specifically designed for smaller, fixed-wing, Part 23 aircraft. Weighing just 10 pounds, they are the company’s smallest and lightest aircraft batteries.

Company officials say the introduction of the TB14 and TB28-12V has expanded the True Blue Power main ship battery product line to serve all aircraft markets. The company now has lithium-ion batteries ranging from 13-amp hours to 60 amp-hours. The certification plan for the new TB14 and TB28-12V includes STC approval for an extensive list of aircraft models.

“True Blue Power is known as the world’s market leader for lithium batteries, recognized for top quality and reliability,” said Todd Winter, President and CEO of True Blue Power.
