I would strongly recommend an internal fuse for each of the DC jacks. The short circuit current for the battery is much higher than 16A and must therefore be protected. Risk of fire!

KZread recommended this to me. 6 years later and a name change, but I hadn’t seen it. Really enjoyed the walkthrough and EE lesson :)

This was the first video I saw of yours after I subscribed 5 years ago. It is amazing how far you’ve come in such a short time. ❤️

Quick tip: Use a conical shaped step drill to make perfect holes in plastic without having to keep changing to larger diameters. Once you get the smallest hole started, larger sizes will stay concentric. If you're off a little bit locating the smallest hole, you can add a little side pressure on the drill to move it back where it belongs as it gets larger. Also, a plywood blade cuts aluminum much cleaner than an abrasive one.

Be careful with the small UPS units when adding larger batteries. They don't have the thermal dissipation for extended run time. I had that exact model that I connected to a 35AH battery to power a small computer that hosted a web server. We had a power outage that lasted 2 hrs, and the transformer got so hot that it started melting the varnish and insulation on the winding (you could smell it) and it melted the plastic casing. It didn't actually fail though but was definitely a fire hazard. The small ones are only designed for short run times, where they wont heat to critical levels, and clearly id did not have any over temperature protection. My much larger APC Smart 1400 with 2 55AH batteries that can run my quad core desktop with 6 hard disks and 2 monitors off the grid for 2 hrs had no significant heating issues. Granted it is also a model that has external inputs to ad additional battery banks so it is designed for it. But it also has MUCH more ventilation and a fan that kicks in to cool the unit while off grid, and also runs during charging. If you are going to try this on a small UPS do a full off grid test a couple of times while you are around to make sure nothing gets excessively hot. You don't want it to catch fire if your power goes out and you aren't home.

The models that use switch mode inverters do not have this problem. But it is better to choose a model with external battery provision even if you do not use the oem over priced battery. I bought a used br1000g in 2020 for 20$. It was retired from an office that replaces all equipment every 4 year. & Even though the original 2x 9ah battery were in the unit. They were pretty much dead. They would run for like 5mins with no load and even 50w would immediately shut-off. I bought 16 Lifepo4 cells. 32700 6000mah 3.2v & made a 12ah 25.6v battery. Lifepo4 is proper replacement to leadacid with similar voltage curve. I did not have to dig with apc upsd and change & charge parameters. It would charge the cells at 3.75amps when external battery mode was enabled. & Run 300w load for 50mins which is similar runtime of 6x9ah battery according to apc runtime chart. So it was essentially half as cheap to buy Lifepo4 & they are holding full capacity as of today & even if they fail after 5 years it is still cheaper & better than leadacid. 1 oem apc battery goes for the price of all 16 cells + cell holder+ bms 😂 & i would need 3 of them to have the similar run time.

If fumes are a concern, you can get a sealed deep cycle car battery for about $130 at Sam's. You could run all electronics for days if needed and the batteries last for many years instead of 2-3.

The problem with your external battery is that is has a MINIMUN charge current specified by the manufacture and the bulk charger designed for the 7Ah battery is woefully underpowered to handle that. Also, the UPS that you modified was not designed to run at 100% duty cycle for hours. It's a packaged system and you just decided to make it do what it was never designed to do. Yes, most UPS are not only designed for orderly shutdown of the computer, they are INTERFACED to the computer to initiate unattended orderly shutdown.

@@DiffEQ I had considered that and modified it accordingly. I added two heatsinks to the inverter switching mosfets (mounted on isolated aluminium plates) as well as a case fan to circulate air through to include the transformer. The charge current for a 7Ah battery is fine with larger batteries, only taking proportionately longer to recover a full charge. Lead acid has no minimum charge current, and long slow constant current charging actually extends their cycle life. I did supplement the charging with a 200 watt rooftop solar panel and MPPT regulator, both charge systems use independent CC/CV and don't affect each other adversely. It has now done many long outages, one a year back lasting for two days and running two 7 hour sessions with no problems, no excess heat and good overall efficiency. I would not recommend the modification unless you know what your doing, first checking that the battery is fully isolated from the mains supply (some are, some are not) and other mods like adding mute switches for alarms, thermo controlled fans and isolated heatsinks calculated for required energy dissipation under full load are things not to be guessed at. Beyond that they make a very cheap upcycling project that works well. I have also since increased the battery count to around 250 Ah working, and it can give me almost unlimited run time between solar and generator recovery during daylight.

Not sure where you're going with the dislike of switch-mode vs. having an "actual transformer". switch-mode power supplies are more efficient than linear. Plus, they're lighter and smaller. If they're "burning up", it's because of a bad design. What I would point out is that these inverters usually output a modified square wave, rather than a pure sine wave. This will run a PC fine, but it will buzz a bit. Please please please put fuses inline.

A stepped but has its cutting surface on the side of the bit. They are basically intended to enlarge holes in thin material. They do.this very well and one bit can cut several different sized holes depending on how many steps it has and how deep you push the bit in. They come in configurations with size of hole and depth of step being the two characteristics people are generally interested in. Anyway, I just wanted lto share a tip about using Stepped Drill bits, hopefully others will find them as usefull as myself. If you have ever drilled a hole in some appliance's thin metal case and marvelled at how you now have a ragged hole a set of dull drill bits....you are gonna love how much better a stepped drill bit performs.

Very clever work. Really made me think about what I could do to keep my computer from frying every time there's a thunder storm (Lost my 120W Speaker Sub 2 weeks ago during a thunderstorm, because the power strips didn't surge-protect for some reason).

It is a shit work! And the surge-protected power strips are not for you. Those are the last level of a complete protection. If you use a power strips with surge-protection, you can aim your all the devices burn in it. You need T1, T2, T3 levels. Do you really think you will be protected with a power strip??? Do you know anything about how they work??? What do you think, why are the complete protection on the roof and in the electric box for??? ALL OF YOU DON'T KNOW AAAANYYYYYTHIIIIIIING!

This has confirmed my plans for the UPS I just found in a recycling pile. It's going to be the centrepiece of my power distribution system for my shed in a rural location, with solar going into the battery via an MPPT, and DC out for the lighting & small 12v cooler. The transformer will function as an added bonus, where I can run AC appliances on demand, without having to think about it too much, so long as it's sunny.

I know I might be late to the party for this video, but I was thinking about a minor upgrade to your modification: Instead of using a switch for the LCD display, you can use a simple button with an RC timing circuit, and make it so it turns on the screen for a fixed amount of time and then it turns off automatically... I have a tendency to switch things on and then forget about them, so I started using this approach for my projects. On a side note, I haven't thought about using an APC like that. I have a car battery with a charging circuit and a 3D printed hub where I put all my connectors. Of course, I don't use it with my computers, its just for things like cell phone chargers, and a hand radio (which has a switch to bypass to mains in case I need it).

I love how modern apc ups's have like majority of this stuff built in XD

wow this just popped into my feed almost 5 years later. Great vid tho. Those barrel jacks are also great for getting some good runtime out of a cable modem and router. Just make sure the battery doesn't discharge beyond about 10.5 volts. Most of its energy is discharged at that point, and draining more will damage the cell.

Wow! Ur videos always inspire me. Neat and precise as always!

dude.... grinders on ally is a big nono, particularly if its a normal ferros metal disk, the ally dust is explosive and/or you can gum up the grinder and the disk can explode. if you've cut steel previously it can even create thermite.... the dust is also highly toxic. cutting ally with one just makes heat, which is why your cut looked like melted cheese. Get a hacksaw, or a jigsaw (with ally blade) or a ally blade for your cutoff saw and you'll do it 100x easier and neater, with 0 risk of exploding bits of grinder disk flying around your house, or explosions from the dust, or health problems from the dust...

Nice idea! I have an old APC backup that I haven't used for years.

I had a big ups for my computer setup 1.5k watts (with runtime 90mins) in 2005 (finally died in 2014). The problem was fan noise. The internal fans 2 x 4" were obnoxiously loud (high cfm). I did a similar project to create a housing for air outlet tubes to external 6" PC fans (much quieter). Fans were powered off internal dc power and fan speed passed to the UPS system.

Cool video, and inspiring a similar project for me with a APC BP500UC that I got off the free table at work. The battery tested out very poorly, so I've ordered a replacement for about $25, and it should be up and running. A couple of thoughts though: the battery in these units is usually a 12V 7AH RBC2 unit. These units have a typical max discharge rate of 1C, meaning you really shouldn't be pulling more than about 7A from this battery. In fact, if you look at the battery datasheet, you'll see that high discharge rates like this will also reduce the effective capacity of your battery. The hypothetical "pull 48 A from your battery" condition isn't sensible: Even if the battery could do it without swelling/heating/exploding. you'll only get a few minutes of runtime, at the expense of seriously reducing your battery life. I might instead consider an inline fuse to protect from large current draws, probably at the 10A level.

Puekert's theorem states that the battery will be seriously derated beyond a C/10 or C/20 rate depending on the how the manufacturer rated the battery. That said, you are absolutely correct in that this is an absurd expectation even from the 9Ah battery in his video since those DC jacks are canonical and only rated up to 5A.... no matter what Amazon ads say. C/1 is extreme and I seldom design a power plant at anything above C/10 unless I have generator and an automatic transfer switch. Even then, I will bump my LVDS so that the batteries are disconnected much sooner than when I build at C/20 rates. I can also use my temperature compensation probe to monitor battery temp and disconnect on high-temp fault. There are many other things wrong with this "hack" and you read about them in my main comment. Cheers!

That's a really good idea bypassing the transformer. Those things are notoriously inefficient and as you mention they do run hot, though not as hot as cheap solid-state models. I currently use a 2.1mm quad (4-way) splitter to power all my 12v network equipment (Obihai SIP Gateway, Cable Modem, Router, battery charger for AA\AAA\C\D that runs off a massive 12v 10A brick that itself has about a 10% loss (and draws 100mah in standby!) and this mod would bypass ALL of that.

Oh yeah that’s right.....

I am concerned that if you are using this to power 12V devices, while it is plugged in, you could overdraw what the "trickle charger" can support.... then what happens? My guess is that it is only rated for something like 2A@12v.

I have been scheming on how to build a battery backup for a portable battery charging kit for my photo and video equipment, this video helps immensely, the type about chargin straight from a DC source is key, now I need to figure out how to feed my chargers DC power instead of AC power

This and the TV RGB mod are so good to watch

"Once or twice a year...". More like everyday here in Cambodia.

The whole converting up to AC to get it back down to DC is one of the things I used to laugh about when car tuning nuts used to put a PS2 in their car with an inverter... the internal voltage of the PS2 is 12V, so instead of using an inverter to get it up to 220V (Europe) AC, to then get it back down to 12V DC, it was a lot better to just remove the power supply from the PS2, and run it into the battery via a small surge protector (power can spike in some cars when you turn the key to start the engine)... this also eliminated part of the PS2 overheating issue by removing one of the elements that caused the heat in the first place, apart from making the PS2 very "cuttable" to reduce its size to make it fit anywhere better. This was good for camper vans too because on those things, if you don't have a solar panel system installed, power can be at a premium!! Same thing for a number of other consoles, like the Gamecube for example (which is easier as it's just replacing the external brick... no need to open the console at all)... but everyone at the time always wanted the PS2 Also, I know this is a bit late, but for those USBs, if you wanted to embed them with a switch, I would recommend making your own using a UBEC like we use in radio control hobby. Those cigarette lighter adaptors tend to lower the 12V to 5V by just burning off the excess 12V, which is a total waste of power, where as a UBEC uses a switching mechanism to reduce the voltage, and not waste more than it uses... much more efficient, and you can get them in a variety of amperage capabilities.

But as the APC battery starts to run low, the inverter will still produce 110v, from which you can get 12V with your power supply. If you plug directly to the battery, you get 12V, then 11v, then 10v. Well you get the idea.

Simple math => you have a 7 Ah 12V battery and consumption of about 0,9 Ah, so 7 Ah minus 30% of capacity as a minimum healthy level of the battery we have a just 4,9 Ah as a working capacity of the battery. Then 4,9 Ah ÷ 0,9 Ah = 5,44444 hours of light in total on a battery supply. Am I clear now?

You need to check the battery leads and make sure they are isolated from AC or you could end up with a dangerous shock hazard. A lot of UPSs have the battery connected to one of the AC lines because it saves money and, because everything is behind the plastic case, it's pretty safe. But if you bring those battery lines outside, treat them as electrically hot until you've checked them against ground for AC voltage, and do the test again with the power hot and neutral reversed on the plug, since you don't want to bet your life on every outlet being wired exactly right. (And don't ask how I found this out.)
