I have sat idle for an hour or more and have tools to monitor temperatures. Also in Florida and I can tell you that you have nothing to worry about. It will start and stop the engine as necessary to keep the HV battery where it should be. Running the AC will make it cycle the engine more...

I have the same one and have used it to carry two paddleboards. It works great for that. The hitch is rated to hold 400 lbs of tongue weight. As long as you stay within that and don't overload the bed with other stuff, you shouldn't have any issues. If you come close to the payload capacity and...

I’m not confused. I know exactly how it works. I’m pointing out that if you accidentally leave it on or a load being pulled from it without the truck running your battery does not add much of a buffer. The truck has an auto shut off feature that goes off in 30 minutes unless you disable it every...

I don't know what the Auxiliary power distribution box is or where it is found. I haven't seen anything with it unless it is the fuse panel in the floor board of the passenger seat which I doubt because that has more than 40 amps. If you really wanna know, pull the fuse and see what shuts off...

In the very rare case that someone has a maverick with those items, a larger, probably AGM, battery is the answer.

The 12 volt battery under the seat has the 200 amp fuse. What you quoted from the service manual is the high voltage fuse going from the high voltage battery to the DCDC converter. Two different fuses. I added a picture of the battery terminal with the fuse attached.

The battery has a 200 amp fuse on it making that a hard limit. I only saw the DC/DC converter get up to 170 amps charging with typical around 80-100. Peak draw that I saw was 60 amps with typical around 20-40. I would say you should be good with almost any small 12v accessory with only high...

I would usually agree with you but it does the BMS retrain feature that could change it. I did do that retrain and it could have changed. You can do scan tool things through the truck with combos of buttons and things For example setting the Ebrake service mode

It was already charging at that higher rate before I did that but it may have changed the max charge voltage

Do you have a scan tool and original battery to check your truck? We could test your theory

It’s for sure a fun discovery game to see where you can fit stuff. Just have to prioritize what you want to have in the storage compartment. Car electrical used to be really easy but now it’s a little more complicated. Hence doing all that I’m doing

I haven’t looked but I highly doubt it would fit. 400 watt inverters are very small. Adding a thermo electric cooler is not worth the hastle or battery drain to run it. A fan and some heat sinks would work just fine

It cannot use the HVB in the middle of the night unless you start the truck. The HVB is disconnected via relay until the vehicle is started

The truck converter can for sure keep up with 1500 watts. Should be easy change especially if its a prebuilt battery designed for car used like the Dakota Lithium. should be plenty of room in the compartment with the trim removed, if not, behind the seat may have enough space if you have a more...

Ford doesn't need to change anything. Its features that work while the truck isn't on. People want features, ford puts in those features, those features take energy. with the truck off, I am seeing less 5 amp draw from my battery pack so yes a 5 amp charger would work to keep it topped off. I've...

Some Updates: Got into forscan to look into some changes. The battery type was already set for AGM. My guess is that when I did the reset, the truck found the power curve most closely represented AGM and switched itself. I cannot find anything that changes anything with the DCDC converter...

I didn't say it wouldn't be a mild PIA to disconnect the battery. I've done it probably dozens of times in the last week or so. Can confirm, some setting reset but not all and its pretty quick to reset them. Less time to reset than it is to set up a solar charger or go start and move it every...

gotcha, when it comes to long term parking, I think that a battery disconnect or small solar charger is the best bet. Significantly cheaper than replacing the whole battery. as for the inverter, I totally think that is possible. I also believe the truck can charge the battery fast enough that...

I apologize, I don’t think I’m understanding what you’re wanting to do with it

I mentioned heat in a earlier post. It is getting up towards the limit but hasn’t hit it yet. There’s decent amount of heat in the compartment already from the exhaust under the truck. Using bigger cells and a beefier BMS could offset that heat due to them taking longer to warm up and generating...
