We were able to get the Micro Minnie FLX out for a weekend trip and so far, we love it. Only a couple things that we noted…

  • AC & Microwave on at same time (while on battery) tripped main breaker which I did not expect.
  • Inverter showed E01 (low battery) and kept cycling.
  • Starlink router is reset to factory settings by rapid power cycling. The inverter cycling tripped the Starlink router into its reset mode. Oops! At least it was an easy fix.
  • Xantrex app does not show battery level accurately at all, but now that I’m aware of that, I know to check the Lithionics app. Xantrex makes LiFoP4 batteries too so I am not sure why Winnebago did not go with their batteries for better integration. I actually wonder if they DO integrate. Who knows.
  • Winnebago panel shows fresh/grey/black levels correctly, but not battery.┬áThis is to be expected, but I guess I wish the FLX got its own control panel that didn’t have a battery button on it. Had I not known this before, I might have been confused and thinking my battery was dead.
  • GoPower app works ok. Seen charge Current of 13.71A, Solar Power 205 W at 1300. This was with the solar panels on the roof, which are 2 x 190watt panels. My Renogy 200w suitcase panel did not arrive in time. More on that later.
  • Lithionics app works ok. Shows a lot of data, and makes it easy to monitor levels.
  • Switched to battery only around 10am, down to 70% with AC on and some microwave usage. At that rate, battery has about 4 hours of usage.
  • AC set to about 77 was quite comfortable. AC (obviously) does better when door is closed.
  • Plugged back in around 2pm when battery was around 48%

Good Things:

  • Starlink worked out quite well
  • Fridge did well but was affected by ambient temperature, which is kind of expected.
  • Shower did great. Showermiser was awesome.
  • Still have 3/4+ tank of fresh water even after almost 4 days. We took washcloth showers, which helped.
  • Nectar mattress is VERY comfortable. Might need to reinforce foot end of bed.

We bought a trailer! A 2022 Micro Minnie FLX 2108FBS.

It’s brand new and not a lot of real world information is out there yet, but if all goes well we should be able to camp totally off the grid for up to 5 days. We know that mileage may vary depending on usage, but we’re happy about it so far. Some users on YouTube have added good information. SpeedBumpMedia and Joe’s Travels both have them and have been updating their videos as well.

The Winnebago website has more information. Basics? 2 x 190 watt solar panels, Truma heat/AC unit, 3 burner gas stove, ShowerMiser system and tankless hot water heater, 3000 Xantrex inverter, Lithionics 320 amp hour battery, Dometic 12v fridge.

We just got it recently and haven’t been able to get it out camping yet. So far the solar panels have been doing a really good job of keeping the LiFePO4 battery nice and charged. Other owners have noted that they weren’t getting the battery life they expected but I also noticed that they’re in the south/southeastern United States and I wonder if the Trim air conditioner doesn’t do as well in more humid environments. We’re in Northern California and it’s been a lot more dry & arid here. Hopefully in a couple weeks we’ll be able to at least go on a short weekend trip to some BLM land and boondock it for a couple days. We’re going to bring a backup generator just in case. I’m not too worried about water storage or usage just yet. We already camp very resource light as it is.
