Who knew that RYOBI made 24V Tools and Batteries! Apparently they only made a Weed Wacker and Hedge Trimmer. Hopefully you don't own one because they discontinued the 24V line and you can't find replacement batteries for them. My friend picked up a 24V Weed Trimmer at a garage sale. The two...

I thought it would be useful if we could use our RAD eBike battery for back-up power or for camping. I designed and 3D printed a battery adapter. I also verified that you can use an MPPT solar charge controller to charge the battery. You can charge it at 120W while using the output power. Now we...

I bought my wife a second battery for her Rad Power Radcity Step-thru 3 (2021) eBike. I needed some way to attach it to the bike. I designed and 3D printed an adapter that mounts to the rear bike rack to hold the battery. You can lock the battery to the rack. You can also use the adapter as a...

I've got a ton of RYOBI 18V tools and batteries. When RYOBI came out with their 40V tools, I started making 18V to 40V adapters. Now that I have a couple of 40V batteries, I thought I'd make a 40V to 18V adapter. It looks like something out of Sci-Fi movie, but it works (At least for tools that...

People ask if you can use solar to charge your Rad Power eBike Batteries. The answer is YES!. I tried three MPPT Solar Boost Controllers and several folding solar panels. Here's what I found

I've made a bunch of different powerstations based on RYOBI batteries. This project uses the RYOBI 40V 3 -Port charger to make a configurable Powerstation using off-the-shelf components. The powerstation can still charge the batteries, but can be used to run 300/600/1500W Inverters and 30A...

Thanks. You need to have access to the T1 sensor if you want to charge the RYOBI batteries. The ones on Ebay don't have that. I have put my designs on Thingiverse and Prusa's free 3D printer model sites.

Back in 2009 I built a Bike Generator to help Elementary School kids better understand Energy and Light Bulbs. After touring the local Elementary Schools I donated it to the local Community College. They recently called me and asked if I wanted it back since it was no longer working. I thought...

For kicks and grins, I put together a test system using solar blocking diodes. Here are my results

Ryobi 18 and 40V tool batteries have 4 terminals on their connectors. The two outside ones are + and -. The two middle pins are temperature sensors (T1 & T2)

I figured out a hack to put RYOBI's 18V tool batteries into "Charge" model (1200ohm resistor between + and T1).... but their 40V batteries are different and seem to have a digital signal on the T1 terminal. Has anyone figured out how to read T1/T2? Or know how to put it into "charge" mode...

I was pretty disappointed with the new RYOBI 1800W Powerstation. It didn't come with MPPT Solar charging or even Pass-Thru charging. I was curious if this was a limitation of the 40V battery or just the Power Station. After some quick tests, I determined you could charge and use the battery at...

Thanks! RYOBI came out with that new 1800W Powerstation. I think they fell short. Especially because they don't have pass-thru charging. I just determined that the 40V battery is capable of pass-thru charging... I made a single battery Powerstation, but I'd like to combine multiple batteries.

Here is one of my 18V projects:

Ah that's right they are probably just using them is serial config.

Yes the batteries have a BMS. Just didn't think they were designed for being placed in parallel. My RYOBI table saw takes two 18V batteries. I'm not sure if they have an additional circuit to handle mis-matched batteries...

I've been using RYOBI 18/40V tool batteries to make powerstations. When putting batteries in parallel I currently have to make sure I'm using similar batteries (Ah) with equal charges. I don't want a huge rush of current from a fully charged battery to an empty battery. I noticed they make high...

I'm always looking for ways to charge my 18/40V Ryobi batteries when I'm boondocking with my trailer or out bike camping. I have been using a Genasun MPPT Solar Boost Controller on my eBike trailer, but they are expensive (and very nice). I recently found this MPPT Solar charge controller from...

Until last week, RYOBI didn't make a high output Powerstation (They just came out with 1800W one that uses the 40V batteries). Unfortunately it falls short in several areas. It can't use the legacy 18V batteries, there is no MPPT Solar charging, and there is no pass-thru charging. If you are...

I just got the new RYOBI 1800W Powerstation. Unfortunately it does NOT have pass-thru or MPPT solar charging. I was still interested to see if I could solar charge it thru the 42V input charging port. I had a Genasun MPPT Solar Charger from another project and a charging cord from my little...

It came today! I've been waiting for Ryobi to come out with a large inverter / Powerstation for a while. Finally they have come out with a 1800W pure sinewave system that uses up to four of their 40V batteries. Unfortunately the product falls short. Here are my test results so far. I'll...

I wasn't quit happy with my previous 18V RYOBI battery caddy. These RYOBI 18V battery mounts can be bolted down. You can make different configurations to suit your need. I've also provided a 12V socket and switch holder models. For an example, I put together a 2S2P system that has a regulated...

Yes, simple is better if you have the space

I built a bigger system with eight ryobi batteries ( ). I've been playing around charging them with the Genasun Solar charger ( https://amzn.to/2OjCoct ) and the Grin Satiator ( https://ebikes.ca/product-info/grin-products/cycle-satiator.html ). I'm collecting test data. I'm concerned about a...

I built a tilting solar panel on a bike trailer. It's only one axis ( ). You could do something similar

Here is the 3D printed parts site... there is a little info there: https://www.prusaprinters.org/prints/52010-solar-ebike-trailer . Youtube video describes design

Looks like Ryobi finally listened (https://www.ryobitools.com/products/details/40v-1800-watt-power-station) ). Unfortunately I don't see solar MPPT charging. You can combine two together and get 3600W! Here are my projects / / chiding RYOBI

Finally got some weather nice enough to shoot video of the Solar eBike Trailer in action! (although it was only 18F). I've made progress on the Gyro/Compass/GPS control system. I'll have to put a Part II video together. The tilting panel makes a 2X improvement in the solar! (80W versus 40W on a...

Here's an adapter for Ryobi batteries that I made to be 3D printed ( https://www.prusaprinters.org/prints/39638-ryobi-one-18v-battery-charge-adapter-for-solar-pow ). I figured out how to put the Ryobi batteries into charge mode. I have used a Victron solar charger to charge them ( ) and I have...

I've developed several powerstations using Ryobi batteries. Viewers have commented that they would love to make one, but don't have access to a 3D printer. Home Depot had a Ryobi sale where if you purchased two 4Ah batteries, you got a free tool. I already had a supercharger, so I got a second...

I was interested in the 40V RYOBI Ryi300BG AC Inverter, but I didn't want to fork out for yet another battery (I have a ton of 18V batteries). So I designed an adapter plate, battery carrier, and 18V battery connectors. I only have the one Ryobi 40V tool, so I haven't tested it on the other 40V...

I was looking for a 100W folding solar panel that had a USB C Power Delivery Port. I only found two on Amazon. I ordered both and put them thru their paces. I definitely liked the Megasolar better than the BigBlue panels. The Megasolar controller has selectable DC output voltages (12,15,20V). It...

you should check out the VRUZEND battery kits. I've made several:

I tested my array of Ryobi batteries with a load tester ( =AT391P_GmkQKwdFkjrDHUCmIELE5tR-m1SN3klcjgNTQsDZjvXQjb-o5e51W2CSe42ojBSEwpfHTP4ls5NOSboGX1IodJd4nxf8RB7h9nrEFhrbz4eWO77-SRM46FhWcFI1xtuRYu5o6gxVVg8k1PIWaoaPjL1H_xg']https://amzn.to/2G0YuMQ ). The Ryobi batteries are close to their specs...
