Upgraded Haven Electrics

Finished updating the electrics over the weekend. Removed (and sold on eBay) the original Battleborn Gamechanger (for reasons well known on here) and upgraded to a 600ah Vatrer. The new battery fit under the bench just fine, although I did add some blocks underneath for support due to the weight. I'll have to get a piece of vent trim to clean that up later. There is plenty of room under the bed for the cushion from the dinette.

I discovered an issue with the ground wiring being incorrect. In my case, the Current Surge Limiter was installed between the SmartShunt and the battery. As the shunt and mppt controller connect to the positive line prior to the battery cutoff switch (so things can charge while the RV is "off"), the result was the shunt reading 8v from the battery when the switch was in the off position which screwed up all the data. This is due to the CSL capacitors not being charged when the switch is off which impacts the ground connection. I re-ran the ground connections such that the shunt is between the battery and the CSL then added an additional ground to the load side of the shunt to connect up the mppt and monitoring equipment so all the load is captured.

The last addition to the charging setup was the Orion DC/DC charger which prevents the tow vehicle from drawing power from the Haven while towing. This was an issue with our old TAB after we upgraded to LiFePO4 and I wanted to correct it on the Haven. Now we can arrive to the campsite with a full battery.

Also added was a CerboGX and SeeLevel tank sensors (with RV-C to the Cerbo) so all aspects of the setup are manageable from a single interface.

Still on the list is to add a small display screen to the Cerbo and probaly a LevelMate Pro+, but this is good for now.
