    Beginner's Guide to RV Trailers

    The title of the thread, however, is "Beginner's Guide to RVs". I think that's the source of at least some of the discord. Psychological priming and all that.

    When I was FT in a travel trailer my ears were calibrated to the sound of emergency sirens. :-P For boondockers in small rigs FTing could be an upside regarding predictable severe weather events. Vandwellers, for example, tend to watch for and follow good weather because of their limited HVAC.

  4. Sounds like V shouldn't have sold service in the area to begin with.
  5. Caveat - avoid this combination: words that can be found in a dictionary / common phrases; and all characters replaced There are dictionary attacks that translate words to "l33t speak" on the fly using mutation rules.

    Best boondocking batteries?

    The important difference with solar/gen charging is that the LiFEPO4 will not have an absorption period in the normal sense. This greatly simplifies charging. Here's what I mean. Generator (or alternator) charging with lead is usually one of these scenarios: charge with gen/alt until absorption is finished. This requires a long duration with minimal current; an inefficient use of a generator. charge with gen/alt until bulk is finished. This is great for gen efficiency but leaves the batteries at less than 100% SoC, which is damaging to lead chemistries. charge with gen/alt + solar. A good combo because gen/alt can do the heavy lifting in Builk then solar can handle the long duration / low current work. The first two problems go away with LFP, and having [gen or alt] + solar as in #3 is still a good combo. But here is something to consider... [CAVEAT: I am still wearing out my golf carts so I don't have LFP yet. The following is a theoretical approach to #3] Gen/alt are by definition intermittent sources of charging, so we can charge LFP all the way (13.8v?) if desired and let it fall back; no danger of holding at 100% SoC too long. Solar is a relatively constant source of energy so it may be productive to reduce solar charging setpoints to whereever we want the bank to hang out most of the time. 80% SoC? 60%? 50%? I suppose this would be a function of capacity and overnight loads.
  7. Well, there is no way for the user to know without seeing the dumpfiles (from darknet or similar). The site knows because it's parsing the dumps. In some cases, like the 500k accounts exposed in an earlier Yahoo hack, the passwords were stored as plain text and so are directly accessible in the dumps. In some they were unsalted hashes which makes it harder; common passes would be identified at once from password and common language dictionaries. Salted hashes usually make it impractical to crack for normal value targets.

    Single data device - where's the deal?

    I'd start reducing bandwidth with some simple changes and see how close that gets you. Add money to the mix only if conservation doesn't help. :-)

    A dumb charger that just has a target voltage doesn't have a Bulk stage. It doesn't have any stages as far as I know. A normal three-stage charger with a Bulk stage will be constant current / rising voltage during bulk up to the absorption setpoint. I don't seem to be alone in this opinion (Forgive the formatting in the following quotes; I could not paste as plain text in this browser): from Battery University: from Trojan: from Iota from Chargetek: What am I missing?

    I don't understand how Bulk stage could have a voltage setpoint set too low when it doesn't have a voltage setpoint. Bulk is constant current rather than constant voltage, right? My guess is J-T meant referring to the absorption voltage setpoint being too low. If the broader point is that "OEM converters generally fail to charge batteries properly" then I'm on board with that. :-) Don't know if I mentioned it in this thread or elsewhere, but I got around the problem by homebrewing that functionality out of a 24v power supply and an inexpensive-but-configurable MPPT charge controller.

    Best boondocking batteries?

    Every sentence in the above quote defies my understanding of the terms and experience with the components. I admit the possibility that I am just be seriously confused. :-) Here is my take: PD says this about the purpose of a converter: "The power converter recharges the battery and supplies 12-volt power for the lights and appliances when 120–volt AC power is available." They do not mention the absence of batteries. A converter is only on when connected to shore power, and may have a power switch, depending on model and producer. Always on does not mean always charging. Indeed, in the proposed batteryless system there would be nothing to charge. there is no bulk voltage that I know of, as bulk stage is current limited. Perhaps you mean Absorption/acceptance voltage here? I do not understand the claim that a converter with 3 stage charging is not a charger by any usual definition. PD even calls them converter/chargers. Bluelghtning's question and comments is more like what I would expect.
  12. Right, it's not tethering as it's not providing network access to the display device. It does use wifi in a peer-to-peer mode (not through an access point). I think you already know this but I wanted any interested onlookers to make the distinction, too.
  13. I would also recommend making backups before you need them; and run windows on a virtual machine; or run linux

    How to Determine Hotspot Usage?

    Log into the hotspot over it's default LAN IP ( or whatever, see the particular manual). That info should be front and center, or maybe on a Status tab or similar. Varies by device.

    Here's a demo of a tiny panel overcharging a battery (no CC): PWM controllers are so cheap it is false economy to skip using one.
