What a great diy video! You even went to the trouble of making a parts list with links. Very professionally done. I'm new to your channel, but very impressed with your skills.
Your Ryobi projects are very cool! Thanks! I watched some of your 40v inverter projects and was wondering if you had more details in paralleling them? Is it the same paralleling the 18v batteries?
Here's an 18V project I did that used groups of two batteries ( ruclips.net/video/lAAWFCU4iEM/видео.html ), but I didn't do the blocking diodes at the time. Just required that you only used fully charged batteries
@@SerendipitySue Hi Chris, love your videos and hacks. Did you come up with a way to solar charge and passthrough this three port power station ? I'm trying to make my big 6ah Ryobi batteries earn their keep by making two or three of your power stations in conjunction with solar panels on van roof and using them to add a few miles to my hybrid vehicle. I want to make them power a 220v inverter to power an extra level 2 charger I have to add a few miles while parked away from home. Not sure if the level 2 can be tricked into charging like the level 1 charger can be by using a bonding plug into spare inverter outlet. In worse case I can use the level 1 charger on a 120v inverter.
In my other project ruclips.net/video/TCWndCrfHi8/видео.html ). I had to get rid of the charging circuit to make room for the thicker wires and DC-DC converter. I'd have to go back and look at a new supercharger and see if I could solder the thicker wires and bring them outside. You would need six blocking diodes.
@@SerendipitySue that would be amazing to see. I was trying to figure out how to still use my charger as a charger and a power station. 1 other questions : when you drop down the power from 18v to 12v is there much of a power loss. I used a 40 v inverter and hooked my batteries in parallel.
@SerendipitySue any thoughts on whether this 3-port charger can be powered/charged via solar with some internal hacking? It would be a nice alternative to the crazy priced Power Station.
Thanks for the quick reply, Chris. I’ve watched many of your videos on solar charging Ryobi batteries and learned a ton. I’d like to use the 3 port charger to be able to power up 3 batteries in sequence using solar. I know the 1800 watt Power Station can do this, but not sure if that’s also possible with this 3 port. Thoughts?
Fantastic work and great documentation! I am currently building out a chargeable/hot swappable version of this for a small camping power station this summer. I had a few questions about the diodes you used. 1 - Did you worry about a short being introduced by two diodes sharing a conductive heat sink? I didn't see any insulation that would prevent this but I know very little about these stud style diodes. 2 - Can I use something else that functions as a high powered diode? Specifically I am looking at the 70HF120 Rectifier Diode since it's much lower cost but I am worried about it being a functional sub. Do you think this would work? @SerendipitySue
Curious (not being a smartass) Why not just buy the 40v inverter… Would t that be easier than trying to make one and hope all the connectors and capacitors are right? Or is there an advantage to diy Legit curious
I designed an adapter for the RYOBI 40V battery. The model link is in the video description ( ruclips.net/video/hKc6IsjtHX4/видео.html ). You can hook as many batteries together as you want.
Would you mind explaining the reason for the diodes? I was thinking it would be a good idea that all 40v connected batteries share the load allowing for parallel sharing (diodes prevent bidirectional current, so remove those), meaning without diodes if one battery is lower than another the higher charged battery will help balance each other and the end resulting capacity of all batteries allowing you to hot swap easier? add a 6ah battery to a 1.5 and the all batteries die at the same time without the diodes.
Ideally all three batteries have the same voltage and will equally contribute to the load. The reason for the diodes is that if the voltages aren't equal, you can easily make an arc welder! A large amount of current (as much as battery can provide) will rush from the full battery to the empty battery. The result would not be good. Unfortunately I don't know of an inexpensive device that will let the current flow in the reverse direction at 2-3A (which is the normal charging current)
@@SerendipitySue A solenoid or relay is cheap and will do what you want.. but I don't think it's necessary, here are my thoughts and I look forward to yours as well on this... the concern if I understand it is the battery seems to have the ability to dump its charge very fast" first off these batteries have PCB boards with MOSFETs that try to force 40v at all times even when the battery is max full or nearly empty. Current can only go up if the voltages are X percent higher than the destination... like flowing water depends on how far you tilt the glass, sure these likely have 12-16x 18650s in them which could means 3 amps per cell, but the key here is a battery can only ingest current at the rate of its chemistry which would limit how fast the current flows into itself out of any of the battery or plural from the "pool" these batteries I believe are rated a 1c max and that makes your wire size engineered at just over that max at 12gauge per battery into a 8-10 gauge bus bar for three of these. Just like how far to tilt the glass with liquid the flow rate will merge from all three or just two depending on the voltage. If one battery is 43 and the other is 38, then technically only 41 volts will flow into the lesser filled battery which will fill or charge very slowly because 41 as not far off from its Nominal when controlled by its built in PCB again to help preserve the tool its plugged into.

sorry I just saw your comment. I keep the 3 battery charger plugged into AC all the time. You can pull power from it while it is plugged in. Maybe you could use a small solar charge controller and a AC inverter to keep them charged? It would be that efficient though
wondering is you could use an aluminum heatsink bar inside the supercharger with the blocking diodes. then perhaps join the - wires inside the box as well to just come out through one hole with two wires + and - but already block protected. I suppose it will need to be checked for space. will the diodes get too hot or cause other problems?
@@SerendipitySue thanks. I have the same concerns. Do the diodes get really hot? To make it a portable power station like the other one you made though it needs some packaging for the external diodes etc. My thinking was if the diodes were internal then it could be a 40Volt supplu then the other bits would be easier to mount. Problem of course is that the negatives on the diodes would be at +40V if left naked. Thanks so much for every video you do! Dara
What do you do with all the power stations you have made. Would you ever feel like selling one or two? Right now I am making one of your dual Ryobi 18 volt battery powered Ryobi power inverters, 300 watt, that would normally use a 40 volt battery. I am using a gutted Ryobi 40 volt battery, with just the board remaining, so I have the contacts all ready to slide into the inverter. I will put the two halves of the battery housing back together for more of a stock look. Is there anything I need to look out for? Thanks
yeah... I know.. I have RYOBI projects all over the place :-) Using a 40V battery shell/contact should work nicely. I've gotten a couple dead 40V battery out of the Home Depot recycle box.
How to make this into something portable. I want to use it for a Sailboat. Bringing the 40volts to the boat electrical panel. Then the inverter and drop to 12 volts. But the charger needs to be able to go back home to charge. I am thinking of connectorizing somehow the 40 volts combines atht e load side of the diodes. So i would need to somehow mount the diode heatsink block onto the Ryobi charger and have a plug of somesort. Thus is could do double duty - bring it to the boat and plug into the panel OR bring it anywhere and plug into other options. Maybe mounting n inverter on teh ryobi case?
Hi there, I 3d printed your device for the 40v terminal. I have a Ryobi 40v(36v} jet washer and want to use husqvarna batteries that are 36v. My concern is that there are 4 ports on the husky and also 3 or 4 on the Ryobi. I presume one is for balance charging and the other for communication? will I cause damage just running positive and negative? thanks Stuart
RYOBI batteries have the BMS (battery management system) built in. It protects the battery from overcharging, over discharging, overcurrent, over/under temp. I don't know about other brands of batteries. On RYOBI there are four terminals. For discharging you only need the +/-. Charging requires the T1/T2 sensors.
@@SerendipitySue thank you, the thing that confuses me is that you see those terminals on the tool side of connector too not just between the battery and charges
You should be able to do something similar with the 18V charger. When I did it, I removed the charging stuff. You would have to find room for the blocking diodes. It would be much easier to add them to a project like: ruclips.net/video/lAAWFCU4iEM/видео.html
Are the blocking diodes necessary? I’ve connected two ryobi 40v batteries in parallel and their 18v batteries together in parallel for different projects and I could never get any current to pass from one battery into the other. I’m guessing it’s because the internal bms won’t allow voltage to pass through unless the battery is connected to the charger. Which I guess kinda answers my own question. I always used 3D printer adapters that slide onto the battery and have a positive and negative leads coming off, for my projects. However I’d have to remove the battery and place it on the charger every time it died, vs your setup where the the discharge is built into the charger. So of course you need blocking diodes
@@SerendipitySue Hey Chris if I'm not interested in adding a cigarette lighter socket can I avoid the buck converter and if so would I connect the red switch negative wire directly to the negative side of the inverter?
48v. Because they are lead acid they needed 75 - 115ah batteries since you can't dischage them pass 50% The 42" could be had with the 75ah batteries. I suppose Lithium would only need to be a percentage of that.
I'm building a powerstation using your plan running two 40v chargers ib parallel. Can i use 3 heat sinks with one blocking diode for each mounted in each one?
Question. With this set up Will you be able to connect your solar panel system up with the mppt charge controller and still charge and draw current from your inverter
not yet. The charger is serial (charges one battery at a time) and there is only an AC plug. If it had a AC=>DC power brick like some of the small 40V chargers we could do it.
@@SerendipitySue What if we didn't use the charger and used the 3D created 40v adapter connectors and used your method of the adjustable voltage MPPT charge controller. I used your idea without the charger and used the 40v adapters And used 4 - 40v batteries in my system instead of 3 batteries. I already got the MPPT adjustable controller just haven't tried tried it yet. Appreciate your advise.
Or do I still need to use their DC charger and charge their batteries individually? Afraid my Idea would over charge the group of batteries. But if the adjustable charge controller set to the correct voltage I can't over charge the batteries? If my thinking correct?
