What parts do you actually need? Just a new tray to fit the larger battery? I'm toying with this idea for my wife's car if/when the current battery dies. Wish Odyssey made a 51r but at this point in the cars life, I wouldn't spend the money for one.I replace the 51R with a Group 35 if it fits. Also, older Hondas use a smaller negative cable; the V6 version is fatter.
There are Youtube videos. I believe @The Critic did it the right way by sourcing battery tray components from Honda. I did it by slightly modyfing the top bracket. I would look into the bottom tray.What parts do you actually need? Just a new tray to fit the larger battery? I'm toying with this idea for my wife's car if/when the current battery dies.

X2 battery from Batteries Plus.The optima red top battery in my 2014 CRV is getting up there in age believe it is from 2019.
Looking for a good agm battery and hearing the Optimas are not what they used to be ?
Thanks for you advice

+1Don't unnecessarily replace your battery. Buy an Ancel BA101 battery tester for $30 and simply test your battery a couple times a year. They are worth their weight in gold in preventing needless replacements. I went 14 years on my Tundra before the battery started testing a little weak.
You can install a Group 35 in a 2014/2015 CRV by purchasing the Honda OEM plastic battery tray for a 2012 Odyssey and flattening the bottom hold down tabs. A larger Group 24F battery will fit if you also replace the negative battery cable with a longer one (24", I believe).I have been looking into getting a larger battery in the future for our 2014 CRV too. I think I would be looking at the H5 / Group 47 size. It appears that size is what Honda went to in subsequent years, and it's very close in size to the Group 35, except it does have some some small hold-down tabs on the bottom that stick out just a bit. I'm not sure how or if that is going to matter and I'm still watching this subject to learn. In addition the H5 is not so tall.
The charging profile on your 2014 CRV is not controlled by software. It is regulated by a solid state component in the underhood fuse box called an Electronic Load Detector (ELD) that varies the alternator charge based upon electrical demand. The video below shows the ELD on an older CRV, but the 2014 is similar.Also, I have read one report that believes the change in charging pattern (for fuel economy) that Honda started using around this time will not result in full charging on AGM batteries. Supposedly one can, and it would be best, to go in to a dealer and get a software update that "corrects" the alternator charging output from what it was originally programed. That program being optimized for the traditional flooded lead acid that was being used then and not an AGM. As mentioned, this is what I've read and I'm still looking for user reports with AMG to separate the fact vs. speculation.
My 2016 Civic is still on the original battery and shows no signs of weakness+1
I have one battery nearing 10 years old that still works fine.
I wish I could do that on my HRV but there is not enough room....After reading @carviewsonic’s thread and receiving some encouragement from @bbhero, I decided to upgrade the battery in my wife’s Accord from a 51R to a 35.
I ordered the battery tray, battery cover, larger ground cable, new tie-down, both J-Hooks and both nuts from Honda for $128.43.
For the battery, I used a Kirkland 35 AGM, which was $179.99.
Everything fits securely, but it is tight. I think the V6’s wiring harness and air box are slightly different in this area.
