    scout24, there aren't any ethanol free stations near me. I wonder if high test stores better than 89 octane, and if it is worth the difference.

    Which gas stores better? Winter or summer gas?

    Winter is more volatile... which would evaporate easier.

    My experience is that quality gas cans, tightly sealed, and stored well do fine for long periods of time. All my cans are either 1) the original rubbermaid or 2) eagle cans.

    The rubbermaid cans are holding tough, but I buy aftermarket spouts as rubbermaid doesn't sell the old flex-spouts anymore.

    The eagle cans are where I will eventually end up. They are still made in the original design... and are explosion proof.

I called to have my two propane tanks here at the house topped off this week, the young lady on the phone must have thought I was crazy.
    I've used real gas 3 years later with no issues whatsoever in mowers and weedeaters. I never put stabilizer in my gas and my Toro mower starts up second or third pull every spring for the first time and thereafter mostly the first pull the rest of the season.

    Sorry. No they don't.
    I use LiPo cells for alot of things daily, they don't just spontaneously explode. Honestly that's a laugh.
    Not sure how many LiPo packs I have (many) & again use daily, I'v never had a problem,,, ever.

    If I pushed you on the LiPo packs you own or your charger(s),, maybe, you would go to an rc forum to get an answer.
    ,. if not, enjoy them & stop being afraid of them.



    The fact LiPo cells have a balance leads makes them safer than other packs that could have suspect voltage balance.

    Lithium Polymer batteries:

    Several years ago I made a DC powered LED light bar setup for my snowblower. Really clean 'factory' lookin build.
    Made a waterproof enclosure for two 3-cell lithium polymer batteries in series.

    After snowblowing one time in 2018, I decided to leave the batteries in their little waterproof enclosure, just disconnecting the positive lead.

    Somehow they made contact and lit the light-bar (high'ish amp draw) and fully overdischarged my two cells.
    this was a user error on my part, never to be repeated.

    anyway, I revived the two cells the next day & still use them daily today, without issue.

    Lithium Polymer batteries are in more & more things for good reason, they have excellent performance.
    Absolutely, they could power an 'emergency use' inverter in your car, without question.

    I'm gonna come down hard on you due to some falsehoods that, if followed, will eventually result in life/property damage.


    Means literally nothing that one person has gotten lucky with lipo packs for a period of time. Good for you. Hope your luck holds out.

    If I want legitimate info, I will go to the mfg. And all mfgs are saying the same thing:
    Do NOT overdischarge.
    If overdischarged, recharging will eventually result in a fire.
    Lipo packs are to be given the utmost respect.
    Etc.
    Read for yourself. https://power.tenergy.com/lipo-safety-warnings/

    Lipos have a balance lead BECAUSE they are intrinsically dangerous. I don't read stories about nicd/nimh/lead-acid burning down houses.

    There is a difference between afraid and respectful.

    Additionally... to recommend something 1) dangerous and 2) not endorsed by the battery mfg on a public forum is opening yourself up for a nice fat lawsuit when someone gets hurt.

    turbodog, I actually own Lithium Polymer batteries & have used them daily for the last 8 1/2 years, you do not.

    The discussion ends there.

    ::side note, bought a high end notebook a couple years ago for emergency backup,
    the charger for the notebooks' Lithium Polymer Battery in it is 19.5V @ 11.8A = battery performance

    ================================================== ==========

    Disaster ready is not only a plan, but the willingness to try different things & think outside the box.
    Being able to troubleshooting & make whatever you need.

    One thing that concerns me the most are people easily told what to think.

    Can we generally agree upon the original point?

    Lipo batteries lack the more robust mechanical construction of the cylindrical cells common to flashlights, thus must be physically handled with greater care. Similar to li-ion, their charging and discharging regimens must be adhered to; while we've all heard of deep-discharged li* cells coming back from the dead, doing so is a risk unlike NiMH/NiCd/PbA.

    Most inverters do indeed cut out at a given voltage so as to avoid over-discharging their source. It's a near-universal feature in even cheap 12V/24V PbA inverters, which while marketed as being a safety feature likely has roots in more mundane component minimum voltage and current limits. No reason that an inverter tuned for li* voltage ranges couldn't be configured to cut out at a safe minimum voltage.

    Yes, and a lipo-power inverter is a bit of a moot point. Not enough pack capacity to run much load for a useful time. Which is a not the fault of the chemistry, simply the capacity/size.

    Yes, it's not a voltage issue or a voltage cut-off issue (since the inverters take care of that) If the inverter cuts off at 10V, a three cell will only be at 3.33V each cell = non issue.
    but it's the fact they can be used in an emergency.

    A piece of medical equipment, ect...
    Runtime is a factor, units should be in parallel & used just for emergency only, but they will work (13Ah or even 16Ah could possibly save someones life)

    Thanks for the message turbodog

    Depends on the need.

    I had a power outage a couple months ago some ~90 minutes before the end of the work day. First UPS running my monitor + dock died ~30 minutes in. Figuring that the rest were soon to follow I decided to go minimal - powered them all down, undocked the laptop, tethered the laptop to the work phone, broke out the ONE+ 150W peak inverter, connected the phone and laptop to the inverter, then soldiered on for another hour at the cost of ~25% of a 9Ah battery. I could probably go all day if I adjusted power settings on the laptop to save power.

    ===============================
    <> DIY ultra portable inverter system <>
    ===============================

    Acquired a small 12V Samlex* pure sine inverter, paired with two 3-cell Lithium Polymer battery packs (16Ah in parallel configuration)
    To ensure the wattage was a consistent draw, used with two Honeywell air purifiers (72.5W total for both)

    ~note~ normally store Lithium Polymers batteries between 3.65~3.95V,, this test was done at a modest storage voltage of 3.94V per cell.
    Fully charged batteries will obviously give much longer runtime.

    Test I: Both air purifiers ran for 85 min.
    Inverter Auto-Off was 10.39V or 3.46V per cell
    __________________________________________________ ________
    Recharged both battery packs at 8A to 3.94V per cell & ran the test again!
    __________________________________________________ ________

    Test II: Both air purifiers ran for 85min.
    Inverter Auto-Off was 10.39V or 3.46V per cell

    So, average runtime from storage voltage was identical
    again, fully charged batteries will give much longer runtime than this.

    ......Now instead of the air purifiers, picture a piece of medical equipment or an emergency ________.
    Some electronics need pure waveform & that's key here.


    Finally, have the entire setup in a small waterproof hardcase** (w/ foam interior) for a clean, ultra portable inverter system.

    cheers



    * https://samlexamerica.com/products/1...er-pst-120-12/
    ** my setup will be in a Nanuk 910 which has extra room for other batteries ect.

    ~ Including hardcase, approx. 6 pounds total for the system ~

    Suspect I'll be putting said ONE+ inverter to the test tomorrow (or maybe the monolithic 'portable outlet' I have in my work bag) - electrician is threatening to show up and install an interlock and generator inlet.
