Two years was Carpenter's guess.
Mark's current battery pack is built-in and weighs 170 lbs.

Don't know. System is from Zero bicycle manufacturer. He said he's planning a different. Battery installation that will allow quick-change battery pack units. Now has to recharge battery pack in place.

That’s why he kicked my butt on climb-out together at Arlington for our video flight.

Hi
Mark is using Zero Battery's and they are LiNcO It is a type of Lithium
Ion, If I used the LiFePo4 I would have 1/2 the range, and fly for only 1/2
hr. one of my flights at Oshkosh was over 1;10.
Don't worry to much about that misinterpretation of FAR 103. Fly safe and
keep out of controlled airspace. That's what I have been told.
Happy Flying
Mark

Aerovolt Lifepo4 is 336 watts at 3 lbs . 24 batteries is 72 lbs and 8040 watts. If a cruise speed is 72 volts at 50amps that's 2 + hours of flight at a much lighter load. I cant find info on LiNcO batteries? Litium iron should only be 14.4 % lighter but far safer. I m just very interested in the Egull plane to fly around southern Illinois outside of controlled space .

Hi Ed
The 336 rating on your Battery is probably cranking amps, this would not be
the hr rate witch would probably less, Would you check this for me,
Happy Flying

Hi Ed
If we were to use as little as 74 v we would need at least 100 A to cruse
if the battery were light.

I actually multiplied wrong It is a 13.2 volt battery at 28 amps of storage or 380 watts . The cranking amps are 500 amps. But Ive spent the morning updating my files on the new Batteries and there is some interesting up sizing going on. I want to verify some of the data. So Cruise speed requires approximately 7000 watts . A 2 hour flight needs 14000 watts plus taxi and takeoff . Ed
