Mark C. Provided this install details for the EarthX ETX48E in his RV-10
"I was able to get the battery installed in my RV10 today. There was only a little bit of work to do to get it to fit. Here are the notes and links to pictures."

1) The width of the ETX48E is an exact fit for the width of the Odyssey
PC925 - so anyone that is using that battery (most all RV10s), the existing angle piece in the battery tray works perfect to hold the aft end of the ETX48E.
2) The depth of the ETX48E is about 1-5/8" thinner than the PC925 (typically installed on its side). I used a piece of UMHD with some lightening holes to reduce weight to take up the extra room in the tray behind the ETX48E battery.
3) The stock battery tie-down lands on top of the battery but is off the back of the center built up area (where the EarthX label on top is). To fix this, I made a 6"x3/8" piece of UMHD and epoxied it to the top of the battery. The tie-down bar then fell equally on the UMHD block and the exposed battery top.
4) The existing wiring runs from the Master Relay and the Ground Wire were all a perfect length to reach the ETX48E when using the Terminal Adapters to move the attach points to the front of the battery from the top.
5) The screws to attach the Terminal Adapters were outfitted with a lock washer and a flat washer to secure the screws in place. The same thing was done to secure the battery cable lugs to the terminal adapters.
6) A MS25171-3S insulting rubber boot was installed over the top of the POSITIVE side of the battery terminal adapter to protect the exposed terminal. It also protects it from the nearby battery tie-down bar.
7) The change out took about 2 hours including fabricating the new spacers.
8) The battery worked great and it seems like the starter has a little more oomph than the Odyssey battery.
Thank you all who take the time to help out fellow builders and share with us your experiences!
