Many religious arguments exist in the RV builder community. One of the many in the RV-8 religious sub-group concerns using the front baggage “well” for battery and electrical purposes. Some say it’s heresy to use that space and some, like me, think it’s a great idea.
In addition to the PC680 battery, I mounted the B&C regulator for the backup alternator and the fuse block for the backup “essential bus”. The “forest of tabs” grounding block is located here. All in all, I think it’s a great place for all this “stuff” and it frees up the firewall for other things.
The battery mount is attached to the sub-floor using eight AN3 bolts and #10 Riv Nuts.
