- 2021 F150 Lariat 5.0 4x4 Ex Cab Antimatter Blue

The 760 battery on my 21 Lariat 500a was replaced after 1 year in service. The dealer replaced it with the same. Living in the northeast with cold winters I've been considering upgrading my battery for the additional CCA's as well as higher reserve capacity when larger OTA's are being installed. It's my understanding that Reserve Capacity is rated in minutes.
After researching this with my dealer's parts department here's what I found out.
The battery tray for all 2021 F-150's is the same part number. ML3Z-10732-D (including the diesel) and it is 14" x 7" where the battery rests. The hold down is the same for all as well. The battery's that were installed are listed below.
I'm not sure if the cables on my 5.0 will reach the additional 2" if I were to upgrade to the 850 I'm still trying to figure this out. The 800 will defiantly work as I've seen on other trucks here on the forum.
Has anyone tried to install the BAGM-49H8-850 in there non diesel truck?
Are there any changes to would need to be made in BCM for BMS when changing battery size?
Additionally, Here the part numbers for battery heat shields / insulators for battery size listed above.
