I’ve struggled for about a decade with portable 12V battery backup systems for use in grid-down or off-grid situations.  Through ignorance and negligence I’ve managed to ruin several hundred pounds of flooded lead-acid deep cycle, Gel cell, and even a high-dollar aerospace AGM battery in the process, as well as purchasing several hundred dollars worth of various 12V battery chargers.  And that doesn’t even include solar charging equipment. For years I’ve wanted to move on to lithium storage solutions, but it hasn’t been a simple path.  I’ve developed a level of confidence when using individual Li-ion cells (3.7V 18650 cells from LG, Panasonic, Sony, Samsung), especially the protected varieties produced by Orbronic and the flashlight companies, but I just never could work up the courage to make up my own battery packs for 12V applications by stringing a bunch of these cells together.  The chances of a fire/explosion due to mistakes on my part when wiring them up with a battery management board just wasn’t worth the risk. But I’ve finally found my solution for 12V storage and am in the process of moving on to LiFePO4 technology, specifically the excellent battery packs produced by Bioenno.  This lithium chemistry hits the sweet spot in terms of safety, energy density, portability, and maybe even price when looked at over the long haul.  I started out with their 20Ah pack with Anderson Powerpole leads and was totally blown away by the performance I got in testing.  I’ve since purchased their new 70Ah pack from Powerwerx and was equally impressed.  Just this week I placed another 20Ah pack direct from Bioenno, since Powerwerx listed them as being out of stock (I get most of my Powerpole stuff from them and typically order some of that stuff whenever I get a new Bioenno battery).  I was contacted yesterday by Bioenno and they informed me that they also don’t have that pack in stock but wondered if I’d be interested in their 40Ah pack with a charger at no extra charge.  Hells, yeah!  It was delivered today and I couldn’t be happier.  I can recommend both Bioenno and Powerwerx without reservation, the money I’ve left with them has been money well spent.

Yes, it’s justified. Because the average person doesn’t fully understand the gravity of this pandemic.  “It’s just a bad flu, right?” No it isn’t. Those pictures are legitimate images of mechanically ventilated ARDS patients placed in the prone position to improve oxygenation.  These particular images could represent patients with non-COVID disease but this exact treatment is what is being utilized in the vast majority of COVID cases requiring mechanical ventilation. Mechanically ventilated COVID cases with ARDS (Acute Respiratory Distress Syndrome) have a lower overall survival rate when compared to other ARDS causes, plus they are requiring ventilators for a much longer duration when they do survive. It’s important to remember that COVID patients only have a 20% chance of being successfully extubated, so far (hopefully this improves with the relatively new data showing that treatment with corticosteriods is effective at preventing severe respiratory and cardiovascular complications).  And those 80% who remain in the ICU will likely die alone because of hospital isolation policies to minimize further spread of the disease. Hospitalization in the ICU causes PTSD in a large percentage of patients.  Plus, a large percentage of the healthcare staff caring for these patients during the pandemic are at risk for PTSD, too.  PTSD is horrible, often career-ending for people suffering from it, and sometimes life-ending by means of suicide. This is no joke.  This is an insidious pandemic that appears to be capable of slowly culling the human herd of its poor, old, unhealthy, and unlucky in the months to years ahead. Basic public health measures, such as contact tracing, isolation, and minimizing contact in public spaces is our best bet for containing this disease at this time.  If these pictures lead to increased social isolation, we’re all the better for it.
