Phase 2 of the electrical system has been in work over the past few weeks. It consists of a Group 31 AGM Deep Cycle battery mounted on the inside frame rail in a custom fabricated battery tray. It will lay on its side with terminals safely pointing inward. Feeding the battery from the truck charging system is a Blue Sea ML-ACR smart relay with manual over ride switch on the dash. 2/0 cables will feed all the primary lines.
Tied into the relay is a Victron 10A AC/DC charger for when we're in shaded campgrounds and have access to shore power or post camping trip to top things back to 100% SOC. If I want to primarily charge the aux battery then I would manually disconnect the ACR with the switch but if in auto or connected mode it would charge all batteries.
To monitor this auxiliary battery I have a Victron BMV-712 battery monitor. It has a 2" round readout in the dash so I can have at-a-glance knowledge of what's going in or out of the aux battery, voltage, SOC, etc. The shunt will be mounted under the hood but will be in a weather resistant enclosure.
All of the Victron products are Bluetooth enabled to work with the VictronConnect app and will all be compatible with phase 3 which would be solar using a Victron MPPT controller and a 100w panel. Phase 3 only comes if it's needed and that will be determined by how often the SOC gets back to 100% by daily driving and during weekend trips.
The aux battery will be feeding a Blue Sea 12 circuit fuse panel with ground buss which will branch out power for...
-fridge
-bed rack main power
-usb plugs in the cab
-cb in the cab
-other circuits as needed
The power inverter that has been under my drivers seat for a long time will remain but will get a proper circuit breaker instead of the fuse I've had. Since I was re-doing all the battery connections it was a good time to clean things up a bit there.
Another side project is I mounted a second Ram mount ball to the dash for a ham radio mount and just general wiring and dash cleanup. Over the years things had gotten a bit cluttered and it was beginning to bug me.
Pictures coming soon.
