That is what @@@ I @@@ want, a simple device that allows you to choose battery voltage, and then allows you to clip on to any battery (or set of batteries) and charge it using 12vdc. That would be SO VALUABLE.
Love your projects. As of November 2022, check H Depot online: Ryobi’s combined power supply/and CHARGER unit for 18v has finally arrived. They are still selling the similar power supply-only device, so look carefully for the one that includes a USB C Input that will allow charging a battery as well as using device as an inverter/USB charging unit. It comes with a yellow USB cable and an AC small plug with USB-C out for the cable. I’ll be using mine with another brand USB 20 watt solar panel. (Ryobi’s own 2 panels are not out yet… they promise to offer both 14 watt and 21 watt folding panels soon.)
Yes, just got one of these! Its Ryobi Model RYi150C 150W Power Source. The USB-C PD charging input on the device should be compatible with any solar panel with a USB-C PD output. The maximum input power to the device is 30W.
Excellent! I did this with my Victron Mppt 75/15 and 200W Portable-Foldable solarpanel. Next thing is to hook it up into Home Assistant (HA) Smart Home system and check if i can add some solar into usable energy (test purposes). Home Assistant is all out support bone for many may many smart devices for home. Of course you can make you own too with ESP-8266 / ESP-32 IoT-boards. I've made numerous thermal meters and plant moisture-sensor. All accesible via Internet.
Very good job. I got tiered of Ryobi being unable to build a power station/solar generator that has pass through charging. Thats so insane to me. So I built a solar gen that uses LiFePO4 batts. Then I just plug a Ryobi charger into it. I can charge multiple Ryobi batts if I need to also
Good afternoon y’all. I think your very impressive. Because you are not 20 years old just trying to show how everything fails. You are calm and explain how you did and where to get the info. You are plain and simple. Just how to do it. That in itself is what more of us need to do. With that said I cannot do what you do. So I may have missed it along the way but do you have a place where I may purchase items. Whatever you can do will be much appreciated. And please keep making your videos. Thanks and I hope and pray that y’all have a great day.
This is a super cool project, and demonstration of several skills. Your presentation is also well done for those of us not as familiar with rigging up solar. Thank you! I just picked up the 1000w version of the Ryobi inverter. I was hoping to come up with a slick solution to go straight from a larger (220w?) solar into the car battery posts so I could run the AC ports to run something like the 18v 6 battery super charger. Don't suppose you have considered that? I guess I just don't understand the value of having the 18v charger in this solution when you could just as easily plugged the unmodified charger into the AC port after connecting the panel to your 800w inverter. Am I missing something?
Have you considered seeking out filament that is already the Ryobi green color? That could save a step at the end, and also withstand any inevitable scratching that might befall your creations.
Wow, nice job. One concern, the Ryobi batteries are 5S cells, which at 4.2v each at max charge is only 21 volt. Can the victron be set at 21v instead of 24v?
Chris, I love your work very impressive I intend to do the same thing as soon as I get a chance. I haven’t explored your site very much but can you tell me if you have a list of tools that would be needed to build these devices and the name of the 3-D printer and software that you used would be also very useful. Thanks Paul
very cool. 1) what was the material used on the 3d printer to make it strong? 2) how did you scan the internals then import to make a case, that was magic to me. Is there a good 3d scanning program you use from your iphone to do that?
I 3D print in PETG material. I used a Revopoint POP 3D Scanner to scan the stuff I wanted to make a cover for. I then Used Geomagic Design-X CAD software to design the cover. I don't think the iphone apps would be accurate enough to scan object. They typically require texture to work.
this is inspiring! question: I've purchased the Ryobi 1000w inverter similar to the unit you have with the hopes of using it to hook it up to a lead acid car battery to power our residential sized fridge during our next power outage. Do you happen to know the equation to calculate how long I can power the fridge if the inverter is connected to the car battery? Thanks in advance for your reply.
The 1000W unit can only provide 850W according to spec. My 12V Fridge/Freezer takes about 60W. Most RV 12V lead batteries are 100Ah, but you can only use them down to 50% or you severly reduce the number of cycles you get out of them. So If you assume 50A at 12V, that would be about 600Wh. So you would have around 10Hours of running. This assumes that the compressor was running the whole time. If you use the AC inverter you would probably have less run time. Maybe do a test with your Ryobi 4A battery and extrapolate. The 4A quotes 72Wh.
@@SerendipitySue thank you so much. this is helpful. I'm trying to find cheaper alternatives to purchasing a generator to keep the food in the fridge from spoiling since it seems power outages are beginning to be more common even in the suburbs. Purchasing a $10k Generac is not an option.
So... the hacked 18v battery allows you to put 24/18v of power into the Inverter. . . . . BUT... what is the advantage of doing ALL THAT over just having a cheapo 12v Deep Cycle or "Solar" battery running the Inverter WHILE being charged by the solar? Wouldn't that give you more power for less work? OR just run the Inverter from a bank or 3 8v Golf Cart batteries - being charged by solar?
LioN Batteries are much better for Solar applications. Lead Acid has to go thru several charging phases (not all take full power). LioN allows you to put 100% of energy in the battery while the sun is out. Lead-acid also has to stay above 50% or you drastically reduce the number of cycles. So 100Ah lead acid battery really only gives you 50AH. LioN batteries you can use almost all the power. Lion batteries are also MUCH lighter. Plus if you are like me, you already have a pile of RYOBI tool batteries that you can use.
You might be able to get the job done with much lower wattage using an induction cooktop. Also worth mentioning, the Ryobi inverter can only put out about 350 watts when using the 18V battery input. It goes up to 800W (600W really) when connected to the 12V power source. Modified sine wave.
@@SerendipitySue I was wondering because I did your two 18v batterys wired in series for use with the 40v inverter and I didnt use the resistors on those battery's.Thanks!
@@SerendipitySue I have 18V De Walt batteries and a Victron solar inverter. I also have a slide for De Walt batteries which only has positive and negative wires. I should be able to make a connection to other connections on the battery. Are you able to tell me what connection should be made with the resistor to trick the battery into charging mode? Thank you.
Mate I love the effort that goes into all this and the 3D is very cool but I can’t help but feel the pursuit of using tool batteries for thing is just misguided. There already exists a plethora of quality to affordable 12V or similar voltage lithium electrical gear that would make trying to incorporate tool batteries just look silly. I used to think how cool it was to incorporate the tool batteries in things but soon realised that it would just make everything needlessly expensive except for maybe some particularly niche use-cases. This is why 12V Auto/camping electrical is so popular and it’s for a good reason - much more affordable AND flexible. Quality work and if you really like it, that’s cool but I bet you could also come up with even better stuff if not ‘held back’ by use of tool batteries 👍🏻
When looking for a way forward, in design innovation, doing what is practical rarely results in actual progress. For those of us who have a dozen or more of these Ryobi batteries, more tools that utilize them is a good thing, which is why Ryobi keeps making them. I'm very glad to see videos like this, because it will drive Ryobi to provide more ways of charging their batteries with solar. That's a good thing, isn't it?
If you look at the avatar for this channel, you’ll see that it is a camper, which to me implies that the channel is well aware of the 12V camping stuff. But the channel also has a plethora of Ryobi products, and he is coming up with ideas to give them even more utility for his needs. In this video, he wanted to charge his Ryobi batteries from solar panels, probably so that when he is camping he won’t have to use electricity from the camper to charge those batteries. The generator / inverter is for use when a 12V system is too bulky to take along. These videos don’t necessarily show the channel’s exact use cases, they just give examples of the potential uses for these ideas.
I have a 12V Lithium Iron Phosphate 100Ah battery on my small trailer with 300 watts of solar on the roof. I also have a ton of Ryobi tools / batteries. I could get an integrated powerstation, but they are expensive and I don't camp full time. The nice thing about the Ryobi batteries, is that I can use them for my tools. In a power outage I have a lot of Wh's just sitting there that I can take advantage of. Also some times when I go camping, the site is shaded. I can take the portable panels and set them up out in the sun. Finally, I just like designing/making things ;-)
That was insanely cool. Hopefully Ryobi will get off their butt and finally make this for the market! :)

I'm a Ryobi fan as well, great invention. You should talk to Ryobi about it.
Awesome 👍👍👍👍👍
Awesome job !
Nice video, by the way Hatchbox Pastel Green PLA is a very close match to Ryobi green!
really great video. Thanks for providing such a good list of tools & parts used on the project. very helpful!
Nice job !
what happens if no resistor?
Awesome
Well done !!...
Awesome!!
oh, now I need a 3D printer. The list is getting longer. Great job though. Brilliant device. Thanks for sharing.
Is there a way to set up solar panel with my Ryobi garage door opener? Very handy for off grid operation. Thanks
Can you draw power from the battery if it is charge mode?
yes, you can see in the video that I'm running a 200W lightbulb while charging battery with solar

yes the Victron I have can be set to 21V. It shows how in the video. The parts I used are in the video description
What wattage of the 1.2k Ohm resistor did you use? Do you have a link? Thank you!
I think they were 1/4w. amzn.to/3Lc8Kir
So how many of those to charge the 40v battery? I would like to run my bussines with mostly battery equipment

Why was the current set to 3amps. Can it be increased to 4 amps since you are using 2 series panels that total 100watts
My 18v are the 3-4amps would I still need 21v panel?
Wait, so the Ryobi batteries just accept a higher voltage input and cut themselves off when full? So they're safe to charge from 24V DC sources?
no, you set the specific charge voltage and the batteries will not exceed that.
Why did you set the charge to 24v?
so the victron could set the higher charge voltage
