Lithium battery update on the RV.
It's taken a while, Raewyn has started working for Granger and I'm still doing the oil & gas sector but of late we're more maintaining roads in Northern Alberta. So we haven't had the time to organize time off to go anywhere. We couldn't really boondock as we had lead-acid batteries that were pretty shagged and the lithium upgrade was pretty expensive. 12 volt system update.
Today I have finally completed our 12 volt electrical system. Firstly I had to upgrade the converter to a lithium compatible one. Then install the Lithium battery. At this point we just have the one 200 amp/hour battery which is the minimum required to do the job. Next was to add a DC to DC charger. This is required when the RV is being towed and being charged from the trailer plug. As the Ford has a generic alternator designed for lead-acid batteries. We intend on adding a second battery perhaps a third. at around $1200 CAD it's considerable expense but is a worthy investment.

Below in the 200 amp\hour battery above in the DC-DC charger that is connected to the power supplied from the trailer plug. To the left is 3000 Watt modified sine wave inverter, which needs to be upgraded to a pure sine wave inverter to that we can run the TV. Yere, the wiring is kind of messy but I'll get around to that in good time.
We're getting ready to take the RV out of the shelter to head down to Edmonton then down to Daysland, AB. Yere, I know it's not far but we're dying to get the RV out.
So expect an update soon-ish.
UPDATE: I have finally completed the update. I added a battery charge monitor, Renoligy lithium batteries have a Bluetooth module inside the battery that allows you to monitor charge/discharge rates but the app asks for way too many privileges on your phone and seemed to just upload spam.

The monitor mounted just nicely in the slide console.

I see you can only add one image to a post but here is the completed set up to the right is the DC-DC charger for the power (trailer) socket as the alternator in the Ford is a generic alternator. Underneath in one 200 Amp/hr battery with room for a second. left is a cheap inverter to be upgraded eventually to a sine wave then further left is the circuit breaker box for where the inverter connects to the RV. Cool eh.

Still a little messy. |
