Super Tweety, my 2004 RV7A is a pretty girl, but she's big boned and "carrying a little extra"!
Just did a new weight and balance and she tipped the scales at 1203 empty weight. meaning only 597 useable. I guess you could say "pigs can now fly"!!
Not a lot of places to cut weight... but looking at lithium ion batteries, specifically EarthX ETX 680 to replace my Odyssey PC680. The EarthX delivers more performance and can withstand temps higher than the Odyssey 170 to 113 degrees respectively. Significantly, the EarthX is 11 pounds lighter than the Odyssey and smaller in form. EarthX also has a "thermal battery box" for an additional $115!
I'm thinking about using temperature stickers to see how hot it is actually getting where the battery is installed in the engine compartment - upper left firewall as you look at the airplane.
Does anyone have experience to share on the EarthX Li Ion with Battery Management System? Or something similar?
One of my buddies on here, who shall remain nameless, but with whom I give great respect... says the Li Ion batteries are not ready for prime time...
Also, any thoughts, reasonable, rational thoughts that is.... on getting Tweety a weight loss of about 40-50 pounds?
Thanks in advance for any knowledge and experience shared.
