YOU said that they can be placed in series..........how can this be?

Too bad you used a cheap high frequency, output transformerless inverter in your design. A low frequency, transformer based inverter would have made a much better choice.

Laser saber put inverter with super capacitor and solar panel ran a power chop saw.

Certainly an option, but you will need some of the not so optional items like a battery charger. I decided to go with the Pecron E1500LFP which during the black Friday sale on Amazon thru Christmas was $615. I decided I couldn't get all the functionality with a DIY not to mention the all in one compact design. The Pecron has a 30 amp 12 vdc output which for our off grid camping adventurers will power our Hiker Camper better than any Ecoflow model and at a lower price.

Thank you for sharing this. Great job 👍

No smoke is away good

You want the batteries hooked up first so power has some where to go when you put the panels on

Could you please tell us where you got your Batteries from and where you got your buss bars at please and thank you much appreciated

I would have put 2x4 in the corners to make it more durable

200 AH? Or 100AH battery? Also, did I miss the BMS on your diy battery? I'm no expert. Seems like just one fan, for exhaust, would work with a static vent on the opposite side of the box.

Please watch the video before commenting about fuses, charging, etc, it will save time for everyone.

Thanks I'll try it

Since 2012 we use this kind ,and the only down side you need to replace the battery between 8-12 months after use, the battery life depends on how much do you use it

Thanks for sharing. I wish I went this route before I bought a Bluetti. I’ve have nothing but problems since I went that route. Now I have to spend double to get a decent setup. At least no one got really too sick when the Bluetti failed while I was using it to power a fridge.

Did you beat $375?

Thanks for the video I’ve got a 300 amp lithium just got a cheap hundred dollar inverter so it doesn’t use that much power…. From the battery I think i’ll hook up some heating pads on the battery with a switch to preheat it in cold weather…. put it all in the toolbox along with a 60 amp ion lithium battery charger … the inverter has battery charge display….. so Bob’s your uncle…lol total build 900.00 can

Excellent video. I did this years ago in a trolling motor box using an AGM 12v battery, 400w inverter and the 100w panels with solar controller from harbor freight. Worked perfectly camping for years and just gifted it to a friend. Well done, sir.

It might be close to the same if you have some way to charge it.

Can it be changed over for use on LP

Ty for the video, but wow talk about bare bones. Yes I know it will work.

Not even close to “equivalent”. There’s a difference between being half-assed and equivalent. DIY has its place but don’t be dishonest.

I went the DIY route until fast charging technology became common, along with the steep price drop in higher capacity power stations. I can plug a compact 96AH LiFePo4 power station into a coffee shop outlet and be outta there in an hour.

Yeah nice video, but you can save even more money on temu yeah temu , oh yeah I know everyone hates it, but I got a 600 watt solar panel and 2000 watt power inverter for way way less money and the same for my battery , and they work great, I even had a power outage and was very comfy, I was able to cook and keep warm all for around $300. I'm going to be buying 2 more power inverters and batterys because they are so low cost, don't believe me just try it it works great.

The resistor doesn't charge up on its own.. It's there to charge the capacitors in the inverter. Leave the negative on longer. The larger the inverter the longer you have to leave it on. Always have a fuse.

What size fuse friend?

For half the price it’s not even remotely comparable. No solar input No AC charging No DC outlets No fuses or switches No case No battery monitor Cumbersome and not conveniently portable But seriously, at a minimum you should have added one charging source. Imagine you buy a rechargeable battery powered fan. And they don’t put a usb port on it. You’d be like, wtf

2:00 That battery price reads $320 and when I follow the link two days after the video posted, the Amazon price is now $370.

Sweet!

What kind of battery is it

As a benefit and safety for any newbie wanting to mimic this setup, it is imperative that you fuse your cables, no excuses. Adding a DC on/off switch, or what we the industry call a "service disconnect" will allow you to isolate the battery in the event of an issue. Do not rely on the BMS for over-current shutdown. You can install a MRBF (Marine Rated Battery Fuse) with terminal on to the positive post of the battery. Simple and Safe. Happy Holidays.

You have very reasonable prices there for lifepo4 batteries, the cheapest lithium batteries here cost over 300 euros,and it's not a good brands,but the lead acid is very cheap yet.

Wow i should have searched amazon more i could have saved myself 20.00 I just bought 2 Wattcycle. They have been getting great reviews so

Costs more to build those now, than just buying premade ones

Good video showing exactly how easy it is to build a small "power station." I own 3 portable power stations. Like you said, they are the way to go. I like them because of their portability. I can easily carry a 1kwh portable power station with one hand as it weighs about 27 pounds. I paid around $400 for this one, Anker, and it can run virtually anything I need to run. They 2k inverter makes it very usable. The inverter you use here also has some USB outlets. A 2k inverter is overkill for running lights and charging phones, but it's much more versatile and can run hot plates and such very easily where a 1k inverter is more limited. I've bought several of the lifepo4 12v batteries from Amazon this year and paid around $150 each. That's about what a Walmart battery costs. Take a 2k portable power station, kook a couple of 12v batteries to it, and you create a very capable system that will run your fridge, TV, router, lights, and a fan for quite a while. I have 2 of the DIY systems as they are easily scalable. Their limitation is portability.

Chup gringovideo

thabnk you for the video. however, i did not see any REAL mention of charging. the eco- that you mentioned has a bult in AC charger, ac cord included. it also has a MPPT solar charger built in w/ DC cables. i think that might skew your numbers slightly. would love to see you update this vbideo to include those points- as i am sitting insiode right now, waiting for the snow to srtart. thnaks~!

and how do you charge this battery!

The killer feature for me is the UPS 10ms switch.

Ecoflow has a MPPT charge controller and built in AC charger. Your system has neither. Also, considering the size of your put-together system, you really need bigger battery cables based on possible draw size. Also, a fuse would probably be a good idea while you're at it.

The ECOFLOW Portable Power Station DELTA Max 2000 accepts both solar and 110 v grid as power input. How does the DIY power station in the grid get charged?

Sorry, thumbs down from me. I'm all for DIY setups as I do them myself, but this one is terribly incomplete, unsafe, and most definitely not "equivalent" to an Ecoflow. There are plenty of good videos on RUclips showing decent DIY power stations - some portable, some not. Unfortunately this is not one of them. Some advice for you on using your setup: Get yourself a decent lithium-capable AC charger (assuming you're not interested in solar charging, that is). Unlike your typical Duracell AAs, lithium batteries are rechargable. Also, add fuses, avoid fires.

That particular ecoflow has a 48v battery (14S16P) so it's quite a bit more efficient than a 12v system. But also I think you may have under quoted the price of it. The link you supplied quotes $1699-, making your system around a third of the price :)

The 200 dollar battery you showed is actually 370 on Amazon.

As of now I'm watching this video on a 60" tv plugged into a gaming pc powered by my first solar power system I made. Feels good lol

Okmo batteries are over priced

Can you use the foam bottle that comes with the pressure washer with the quick connect spray wand?

Having the money to buy a power station is good. Having the knowledge and skills necessary to build your own power station is invaluable. I've built several different DIY power stations and enjoy the process quite a bit. I wouldn't exactly call this build a portable power station, though, because it doesn't include an AC or solar input and the output method is very limited.

Good idea and easy. How do you recharge it up when the battery runs low? You did not mention that on your video.

For a different perspective, by the time you add the AC to DC charger, MPPT solar charge controller, fuses, shunt, battery disconnect, 12v fuse block for accessories and USB output, you'll be getting close to the same price. Adding these features would make the setup significantly less portable. Plus a 48v architecture is more efficient than 12v and an all-in-one power station will come with a decent warranty, support, and the option to control and monitor the entire system with an app.

Great Video- I am thinking of this for a remote Ham Radio station
