True Blue Power has introduced two new main ship batteries for general aviation.
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, according to True Blue officials, who note the company now offers lithium-ion batteries for all markets, from experimental and homebuilt to the largest commercial and defense aircraft.

They are starting batteries. Interesting but I got almost 8 years out of my Gill before I recently replaced it. I could replace it three times for what one of these cost.
Help me out here. Since 26 ah is equivalent to .312 Kwh and it takes many kwhs to power a drivetrain for an EV or E-plane. Like 15 kwh to go 50-60 miles in a car and though I have no data for what distance a small plane would travel on that, I’m assuming it’s similar. If these are for prop power you would need dozens of them.
