Chip Yates intends to beat his own electric plane speed record thanks to upgraded battery
During tests, the plane hit 175 MPH at 41% power...Chip Yates is an ambitious dude, always pushing the limits of what is possible. He holds speed records for both electric motorcycles (Guinness World Record: 196.912 mph) and electric planes, he wants to be the first to cross the Atlantic ocean in an electric plane, and now he wants to break his own electric air speed record thanks to a new more powerful battery.
The new battery from EnerDel is a 450-volt, 80 amp-hour pack capable of 600 amps continuous output, the equivalent of 258 horsepower, and twice the output of the old battery pack. It weighs 525 pounds and takes up the entire back seat. If he were patient, Yates could leisurely cruise at around 100 miles per hour drawing only 40 amps, giving him two hours range. But as always. Yates has speed on his mind, and during the first flight with the new pack he managed 175 miles per hour, though he wasn’t at full power.
“Fifty percent throttle, I swear,” Yates told us after the flight.
But he was exaggerating. The electric Long-EZ was able to hit 175 mph with the new system on just 41 percent power. (source)
Here's the test run with the new battery:
