David,
I know you were wondering about the Earthx battery. I have the ETX36E. I am glad I have it, I really needed less weight forward. I did not build my Sonex so I don't know how efficiently, weight wise, that I installed my firewall forward. The plane weighed 669. I wasn't happy with the CG so I added 4 lb lead in the tail. The plane is now 673 and the CG is where the Aerovee CG was. It doesn't help the CG that I weigh 165 including Zulus.(it helps the climb and speed though;)) I also keep 8 lbs of necessities strapped in the luggage area.
I still had to adjust my Dial-a-trim as the nose would drop in cruise at full up trim.
The battery sat most of the winter in the cold hangar and I only charged it once, in December. It doesn't loose it's charge. It turns the engine over nicely.
