Those diodes are going to get hot if you pull any current through them, maybe a low drop schotty will help or go with an ideal diode/mosfet based, also would put the wires up to protect from damage and getting wet
Awesome. Such a clean design too. Ryobi does make a 18v battery power station now, but at about $900. FWIW, what I’ve long wanted to make is a AC power to 18V ryobi battery adapter I could use for my ryobi air compressor. 4ah batteries last about 5 minutes on that thing. I have the skills, just don’t know what the peak power draw actually is to size the transformer and buck converter… although also thinking of just using a repurposed laptop power supply if that can put out enough amps…. Anyway, if you want a killer project, do that one!
i did a similar config on mine without the switches. something i noticed was a phantom battery issue - if i left a slot unpopulated it would still show the testing flash on the empty slot. no issues charging when fully populated. switches are a good/easy way to get around the behavior tho. I like it.
Kick ass!!!!! Have you approached Ryobi toncooy this design for aome eoyalty $$$$$? Is this solar charging capable? Energizer has a small battery bank system that can be charged via solar while being used/ pass thritech. Mechanical neerds/ visual nerds, are a great assest to society!! I see things mire mechanically than electrically/ programming rype stuff.
i hv made one similar to this... with a bit more features. like a built in solar charger... a 480w dc to dc converter. lights.. main fuse and switches. works great and very handy.
Nice video. Was wondering, when all batteries are "on", what the capacity of your power system is. Have you considered adding a bms system to manage all batteries health? What is the maximum load of your system when a device is connected to your 20 V outlet?
I would spend money to make one. But i think there is better in investing in solid state or lifeo4 lithium. Solar generator pre-built or diy system. Something to run high drain devices.
Great! I just got a solarpanel (jackery with usb a and c and 18v Dc out) and would very much like to be able to charge with that. And then also have a couple of usb out. I would by this right away.
Any sujestions on how to design one that drains that batteries in series. I would love to make on where i could switch between higher amperage vs a slow discharge model so i could swap the batteries one at a time as needed for some lower use like a lower draw usb or 12 V device while off grid. The switches are cool but you would have to keep up with status and manually flip between. I would probably so a hack of both depending on my power draw needs
Greetings, I liked your idea of how to modify the ryobi supercharger if you could send me the design of how you have it on paper to do it with mine, thank you, greetings from Puerto Rico
The design in the video as built would probably start having issues at 10 amps due to amperage screen throughput, high gauge wires, single ground, and low amp switches. If all those were perfected with no losses the limit would hypothetically be the combined amperage of all 6 batteries since it's all in parallel. I've seen some 4 Ah batteries pull up to 20 amps each so that would theoretically make 120 amps and therefore 2400 watts at 20v but all the 4Ah batteries would run out in
Simultaneous charge and use is of large importance.
My top wish is that Ryobi would make a 18v version of the big inverter. Impressive build.

sweet! wish I had those skills....
Is there any way you can do a more detailed video on how to do this? I want to give it a shot but will need more help

Commenting from the future, we still don't have an official model like this.. and it's a shame.

nice project! ⚡
Is it possible to assemble a similar station from Bosch GAL18V6-80?
how many watts can you get out of it?
Looks good!
Very cool! How many amps could you theoretically pull from this thing?
