[@bmbiz]

I seem to recall from shop class 100 years ago that you could also put a piece of scrap wood on the other side and drill through and into that to help prevent splintering. I might have hallucinated all that, though.

The sunken cost fallacy is when you have invested too much into something and are reluctant to admit it was a waste of money. If you were only motivated by the amount of stored energy, you could have almost bought two and got twice the energy for what you put into it. But the the experience you gained and the public good of education generated for your audience (who cannot afford to buy foot long batteries) is priceless. This one could have gone either DIY or buy. It depends on whether having extra power was your only goal. Loved the video. Power independence is a favorite topic.

I am a structural engineer who recently discovered the miracle of PL premium and PL Premium Max... also Loctite branded versions.

I think you identified the main problem with power stations you buy - they try to do everything and they cost a lot as a result. In reality, as you have shown, everybody's needs are different - You want USB and mains output and don't need 12v. I need 12v and USB but I don't need mains. I've just finished building my own power station which does what I need and no more. Cost me £120 - with the greatest savings being not needing the inverter and the cabling and larger batteries that go with it. DIY is definitely the best option.

Great job! I vote for home built. I finished my battery compression box the day you posted this. The unit is up and running daily. It has 560 amp hour EVE cells, 3000/6000 surge inverter, 250 amp BMS, 30 amp MPPT, 75 amp on board lithium charger. It was built to run a big refrigerator and 2 chest freezers on 120 VAC power. We lose power more often in Northern California these days. Last year it was only out for 47 hours in August here, but much longer elsewhere due to wildfires and terrible winds. Its in a steel tubing cage on caster wheels but at 51 kilos, 130 pounds, its not portable. The 410 watt panel sits temporarily on the roof on the foam they shipped the cells in.

[@usarms149]

Great video! I did exactly this last year only, instead of charging from a wall outlet, I mounted a 100W Renogy solar panel to the top of the enclosure and included a Victron charge controller to keep the batteries charged. My setup was comparable to a Goal Zero model that costs several hundred dollars more and doesn't even include the solar panel.

[@BeezyKing99]

one mistake you did in your build.... where's the vents for the inverter/battery compartment? you certainly don't want to trap heat in there.

Not a bad build! I used a toolbox, and small 32650 cells all spot welded together for mine. It’s got 2000ish Wh, but the same 1000W inverter. And I used a solar charger controller instead of a buck converter to charge... but I TOTALLY agree, DIY wins hands down.

Tip for soldering bucket ring terminals: hold with vice grips or vice, heat with torch, fill 1/2 way maybe 3/4 max with solder while still heating, dunk wire in solder, hold 'til solid. Perfect solid connection, though do remember the solder can, as always, wick up the wire thus strain relief is always a good idea.

[@forbiddenera]

Tip for soldering wires together straight: put wires together end on end, turn them about 45 degrees from each other which will allow you to wrap them around each other, creating a better mechanical connection before soldering as well as a perfect clean joint that you don't have to hold while soldering. Solder then, be happy. Called a western union/lineman splice.

If you now ensure that loads can be powered from the wall and the batteries at the same time without interruption (UPS), you'd have a pretty cool multifunctional power supply at hand. No problem if the power goes out because the batteries are topped up and ready to help you get through a few days.

[@del_v000]

You were creating A.C. in the old video, fine... but your tesla coils were not good, the arcs were too short/ the circuit was too complicated(compared to slayer exiter). I tried experimenting around with other "bjt" and could reduce the size of the senondry coil to 7cm and diameter 3 inches,wire used about 34 AWG. Primary coil is the breadboard wire, 1 turn. but i got a decent hot arc length of about 1.5 inches and could light up a cfl without being touched to the coil. (atleast better than your part 1 tesla coil). for that i use mje"3055" NPN transistor, 22 k resistor and 12 v(1A). power supply. maybe you should try this or use a zvs circuit, the induction heater you made(for primary coil) for a full sine wave A.C. inverter. You might find it interesting.

[@TinkerbatTech]

I have a couple of small 'power stations' here, inexpensive and LiFePo4 based. Pretty decent. But, as you noted, you have to take their idea of a suitable 'mix' of features, outputs and capacities, and they're rarely in accord with your wants. I also have my house critical systems (except refer/freezer currently) on a battery-backed setup using surplus scooter Li-Ion 36V packs. Now, the surplus quality Li-Ion and lately, LiFePo4 packs out there make a DIY solution way more compelling. You can find all the needed components easily and cheaply to assemble your backup system, or a power station like yours (love the wheels!) with capacity galore, all the inverter and/or DC power you want and the charging options to match. Just several hours to plan, assemble and build. Because there are so many great deals on 36V packs, I was able to find a couple surplus quality UPSes that work great, and under my keyboard right now is a 3000W sine 36V inverter, that'll handle the refer/freezer and microwave loads. And it was easy to use those DC-DC "lab" style power modules to arrange 42V/30A charging. (Using 42V Cisco router P/S as source. Think were 2 for $60? Soo cheap and way quality.) (But see my channel for how not to mount LiPo batteries. Very nasty when poked!) Anyway, if you factor in quality recycled cells out there, (And UPSes! Great quality inverters, low speed chargers and backup. Real cheap Ebay, usually shipped without the failed batteries, so cheaper/safer shipping, and very much life left! I paid about $70 for my 500VA and $90 for my 1000VA shipped. I don't even notice the power drops anymore, except the mini-split stops. Nice.) you can build a beast on a budget! Thanks!

The best part of DIY is you can choose everything like you can avoid the voltage conver to charge the battery by using a charger with right amount of voltage and you can entirely skip or downgrade or upgrade the inverter like 300w or 1200w.also you can choose what type of battery you need like Li-ion or Li fe po4

Very well done, for the full 1kw of continuos power I would have used a set OFC 2 gauge wire, it is still extremely flexible and soft bit would allow for proper transfer. 85 amps continuos through 8 gauge seems a bit weak. That is my opinion however and I build for the extreme as well.

I have a similar commercial "solar generator" battery. I know it's probably possible to build something bigger, but I am perfectly happy with mine. My biggest complaint is that there is no way to charge it over USB. I have a little backpacking USB solar panel, and modern USB-C can charge 100Watts, which is about the same as the brick charger that came with the device. Better in/out USB-C-PD would improve the ergonomics more than a bit more power for me. When camping or surviving a short power outage, 100 Wh per night is plenty for lights and phone and whatnot.
