I am not sure what you mean about closing the hot water inlet valve. The process is: 1. Fill the hot water tank as you normally would (close the drain valve, open the fill valve, turn on the pump, open the hot water tap until water comes out). 2. Turn on the water heater and let it heat up...

Not to put words in the OPs mouth, but I didn't read their post as asking about winterizing their water system, but about *using* their water system in the winter.....

Open the drain back valve on the water heater (the lower valve in the cabinet with the hot water heater) then open the hot tap on the sink, just as if you were draining the hot water heater. Assuming your water tank is not totally full, the hot water will drain back into the water tank. You...

We use out water system in the winter, but it takes some care and depends on just how wintery your winter is. If your are talking about using it where the highest temperature will be significantly below freezing, then it is probably not worth the risk. However for desert SW type conditions...

Assuming a 30A DC-DC converter at 13V, you would get around 1400kJ of energy into your water tank in an hour, which would raise the temperature about 10C. You would either need to switch the heating element for 12V version (not sure if that exists) or use a (large) inverter to power the 120V...

This is an interesting idea. Be a little cautious, at least the first time you try this, as it will max out the MPPT controller and it may get a bit warm. I have a similar approach to use my Victron MPPT as a battery to battery charger (using a boost converter from the alternator) and ended...

At least on Victron DC-DC converters, the input and output negative terminals are common on the non-isolated version, and are isolated on the isolated version, but you can tie them together if that is what you prefer.

I am not sure I understand the question completely - but an isolated DC-DC converter has two separate negative terminals (not really ground) that are electrically isolated from each other (at least in a DC sense), but they can be connected by the user. The non-isolated version has a single...

At 35 psi it doesn't seem that the airbags are carrying a huge amount of load, so as long as the truck is handling OK and isn't squatting too badly, then you should be OK to drive home.

Around 95 - 100%. Remember that the BMV-712 does not use voltage to calculate SOC and there isn't a 1:1 relationship between voltage and SOC.

How much pressure do you normally have in the airbags? If the airbags are carrying a significant portion of the load, then you may not want to drive back to CA without them. Your shocks don't carry the load, your springs and airbags do, so it is a question if the springs alone are...

This is all at or near 100% SOC. I have my Victron MPPT set to charge my battery to 14.0V*, and I also have my BMV-712 set to sync to full at 14.0V. Once the sun goes down the battery drops to about 13.4V almost immediately, then over the next few hours it slowly drops to 13.3V even if I...

I have a 100A non-bluetooth BMS that has been sitting on the shelf since I upgraded to a bluetooth BMS a few years ago. I would be happy to send you if you want to get this up and running while you wait for resolution on the BMS you ordered. I can completely sympathize with the frustration of...

I don't think it is too far off from what it should be. With my battery (which is of a similar construction to a BB with lots of cylindrical cells) I see about 13.4V at the end of a charge cycle, which drops to about 13.3 after a few hours of rest. So 13.25 seems reasonable for 100% SOC or...

Open circuit voltage is NOT a good way to estimate the SOC for an LiFePO4 battery. The discharge curve for an LiFePO4 cell is almost dead flat - ie the voltage only changes a very small amount, around 0.2V for a 60% change in battery SOC. If your Victron 712 is correctly set up, it is a far...

This seems to be a topic of discussion every autumn :cool: . Many of us, even in solidly cold areas just drain the system, and possibly blow it out with compressed air, and have had good luck with this for years. If you use the camper in the shoulder or winter season, adding any sort of...

I am guessing the bike charger has a large capacitor on the input, which is causing the issue. When you plug it in, the capacitor on the charger tries to charge (they charge almost instantly) causing a large in rush current, that trips the inverter. There are a couple of things you could...

Agree with the posts above. We have had good luck at public dump stations (like we have at some rest areas in CO) as well as at BLM/USFS ranger stations and some gas stations. We have also had luck at public parks in smaller towns - there is often a spigot for watering/maintenance use. One...

If you have already removed power from the BMS a few times (reseting it) and that hasn't fixed the problem, it seems pretty likely that the BMS has an issue. Before spending more time on this, does the BMS provider offer any tech support or a warranty?

It looks like that there is either something wrong with your BMS or the BMS settings, the actual batteries look to be fine. What you are seeing is consistent with either the BMS being off or there being a fault with the BMS. The only thing that stands out to me is the setting 'switch...

That is a different interface than the one on my BMS, however everything looks to be in order and the battery and BMS seem to be in sync ie the battery is fully charged with a 13.6V resting voltage and the BMS thinks the battery is fully charged. Silly question, but have you tried loading the...

I don't think there is any issue with leaving the last gallon or two in the water tank - there is plenty of space for it to expand when it freezes and it won't damage anything. We have never used antifreeze in the camper, because we use the camper in the winter. We blow out the shower...

Your BMS is probably off. When you first connect the cells, it doesn't know what the SOC is so it may assume it is too low and turn off. Configure it through the app, and then either force it on through the app, or charge the pack for a bit, which will turn it on. It will take a while to...

I have done (parts of it ) in both direction, and don't think it makes much of a difference. A couple of things to note - it snowed up there last night and will be below freezing tonight as well. Not a lot of snow but it is the season where it can snow at any point. The other is that the...

If you get a 'premium' Gaia subscription it includes digital access to ALL the NG Trails Illustrated maps. I know many prefer the plastic-paper versions, but you can at least see which ones you might want to get based on the Gaia digital versions. To me this is one of the killer features of...
