60G Cube - I can do this cheaply, right? AKA the Mars Mission

[Fenral]

this is great to know. I'm going to look into buying one of these instead of my UPS. Thanks a bunch!

Most ups - use sealed lead acid batteries - which suck… some use lead acid gel fiber mats… which suck a little less…. But the life cycle and storage capacity fall away so fast on lead acid batteries its not funny - and they are known to just quietly go dead without ever being used in a ups. Most NOCs cycle the batteries out on ups on 2 to 3 year schedule.

You can get life4po batteries to replace them in most cases…

Well that 90% capacity is a bit subject to other factors … but the battery in your “ups” - really a power station… is the same tech most people use now in full on solar installs.
They are good for anywhere from 2000 to 4000 cycles at 50% depth of discharge. That number can drop to 1 cycle if you critically discharge a life4po battery - but most have bms systems that cut them off before that happens.

100% correct. I agree completely with your response.

For our purposes we are not experiencing daily, weekly, or even monthly outages and depleting these down to 50% or less regularly. The station does have bms tech. And yes it’s not a ups, it’s a portable power station with built in ups functionality.

Where have you been in all my online battles where people try arguing with me that their apc ups will last 80 hours, or that lead acid is better than lifepo4

Where’s my backup support been? I’m tagging you in next time haha

So I want to look for a portable power station with lifepO4 battery? Is that whats best?

They pretty much all have them

The best bang for the buck are made by big blue in my experience. CellPowa 1000 is a great unit and it’s specs are underrated

Thank you. I might set up a generator here eventually...once I update my panel to be larger.

Generators suck… unless they are propane powered - if your in a longer outage, unless you have a lot of fuel in bunkerage - finding gas can be problematic if the grid is down - the gas pumps don’t work. Plus you have to shut them down for maintenance etc…

I was not on here till recently - and the last time i was on rc i was also having arguments with our resident alchemist - err chemist randy…

Feel free to tag me in I only worked in the energy sector for 2 decades - constellation / exelon …so i have no clue what so ever how energy storage, generation (including nuclear) and transmission works

Well as a single box solution there are quite a few options. Depends on budget etc…. I would estimate Vintages solution would keep a reefocto varios4 pump running at full power for 7 to 8 hrs.

It is far easier to conserve energy than to build a supply set big enough to meet demand. - another reason why this build is part “mars mission”…

Welcome!

We have the same battles as there was years ago. Except now cost and availability are more in our favor.

It’s still more pricy. But not as bad as it used to be. It’s come down and is a viable option for many in the hobby to get a decent power station for outages.

will the 3 prong power cords from my sicce sdc 6.0 plug into the cell powa 1000?

Various 4 is 40w at full power

Cellpowa 600 = 537 wh
(537 x .9) / 40 = 12 hours

Cellpowa 1000 = 1075 wh
(1000 x .9) / 40 = 24 hours

If you can reduce from full power down to 75% power you can further increase the run time. And people shouldn’t be running dc pumps at 100% anyway

Yes it has normal 3 prong ac power plugs powered by a sine wave inverter. Clean power.

When power to the home is lost, or automatically cuts over to Lipo power, in .01 seconds. It’s seamless. When power comes back. It switches back to ac power, and recharges itself

 

[VintageReefer]

I converted my kids power wheels to lifepo4

I can fully recharge in 2 hours instead of 8+

The truck battery life increased 2-3x

The truck has full power start to finish. Instead of crawling at a snails pace for the last 30 min and not being able to handle grass or a hill

The new battery is smaller and less weight also

Not trying to be a jerk - sorry if it comes across that way - but that x.9 i assume is your number to compensate for the inverter to convert the dc to ac - however unless your at maximum performance load efficiency point - even high quality inverters will run at about %80. Also you then have to pay the cost again as the ac is converted back to dc - so its more like a final conversion factor of %60… which means you can run a varios4 at about %77 for 12 hrs…

Okay thank you. I'll stay out of this now and let you and fenral geek out

Coward!

This stuff is out of my league. I need to research and read up more to understand some of this haha.

Totally understand
I believe from my testing and comparison to other brands, this company is underrating their capacities and running more efficient than others

Some brands I test and use the formula and the runtime is realistic with a value of 80 or 85% efficiency

The big blue runtime corresponds you a factor of 90% in the formula.

I don’t believe they have miracle tech operating at 90%. I believe they are conservative/underrating their capacity

Yes much like i over rated my panels to 3.5kva but my mppt will only convert 2.7kva.

Most of the high quality products really are only rating at 80% of true cell capacity - as cells will have some level of variance by batch etc…

More or less lifepo4 are the best solution out there commonly. Lithium Ion has a higher energy density - but die a lot easier.

The best solutions for chemical battery storage are really flow batteries - but i doubt you’ll want to go there.
