3d print files for the battery holder is available at: github.com/pittxprojects/ebike I'll post my motor controller mount 3d file somewhere if people are interested.
Been using 40v toolpacks on my ebikes for about 10 years now. Old school macallister/spear and jackson/qualcast/florabest. 3d printed holder. Thanks for making a vid on this. Imo more people should use these batteries as they are more versatile than a huge ebike battery plus you take the capacity you meed for a given journey.
Dude! Throw up a couple pictures on flickr or insta or somewhere! I've been procrastinating over doing something like this for years. I suddenly find myself in posession of a coupla washer/dryers... Hmmm... 😁
@@imprintwell5436 nope they have their own bms. The only issue with them are protection diodes so the dont do regen braking but my ebike controllers dont have this either. So its no issue. Ive even had then in series for 72/80v but this is hard on them and flyback current can kill the diodes in the bms.
I built two 26” e-bikes using a 36v 500 watt rear brushless motor hub wheel, contoller, and powered it with the Ryobi 40volt battery. The adapter for the Ryobi battery is available on Amazon. It works well but I take a spare battery or two with me as 6aH or my 8ah batteries have only so much range especially on hills. I put kid back seats on the back of the bikes, so with an 8 or 10 year old on the back and me, it’s a heavy rig, lol. God Bless
@@geneandrew1269 I’ve gotten 12-15 miles out of a 4AH battery with light pedaling. Running 2 batteries in parallel gives greater total range and also prevents accidental over current protection. I love using stock batteries and being able to just swap them out.
Yes, that's exactly it. The Ryobi 40V batteries have an internal overcurrent protection built in. I've found that with my 36V/500watt hub motor bike that if I accelerate HARD the battery safety will kick in and kill power. Unmounting and remounting the battery resets it, but it's a nuisance to do. As long as I pedal to get started and avoid any intentional hard accelerations it works fine. Adding a second battery in parallel with the first means only HALF as much current is drawn from each battery. That will prevent the overcurrent protection from activating. Just make sure that when using two batteries, that they are both the same faceplate capacity and start with them both fully charged.
I only just got a 3D printer recently. A friend of mine runs a small business and bought 4 new ones, so I just bought one of the same that he did. I've been very happy with it. Ender 3 S1: amzn.to/3J5l1ok
It works great! Watching me ride a bicycle is very boring. It looks just like riding any other bicycle, except that I can pedal with less effort or completely without pedaling if I'd like. I'll still try to make a "riding" video some time.
In the description, there is a link to FULL PROJECT documentation, including a PDF file that walks you through everything, budget, parts list, step-by-step directions, etc. Here's a link to Digikey for those connectors. www.digikey.com/en/products/detail/te-connectivity-amp-connectors/927824-2/2332032?s=N4IgTCBcDaIIwHYC0BOMCAcYAsSwGEAVJAOQBEQBdAXyA
Also, builders, there're lots of Ryobi knock-offs over on the Big River. I've had a dud here & there but at ~1/2 price, I can'really justify multiples of the branded batteries.
One thing I will say is that the 40V Ryobi batteries have very good built in BMS which limits maximum current output and low voltage shut off. I can not speak to the safety features of the knock-off batteries. The other thing to keep in mind is that this is a battery I already own. There was NO additional investment in batteries. I like the idea of reusing something a person already has.
Whatever happened to your dual 18v ryobi mini bike project? I’m looking at doing a dual 18v setup to add an auxiliary battery to my electric longboard.
No update. It works great. Watching me ride around a parking lot wouldn't be very interesting - it's still just a bike. How much less I need to pedal really isn't impressive by looking at it. What is is the FEEL or experience of it. It's pretty neat to pedal a bicycle and then engage some power from the electric motor. You can feel how much less work you have to do. It's a neat sensation. I encourage anyone who hasn't ridden an electric bicycle to give it a try. Test out your friend's e-bike, or go to a full-service bicycle shop and go for a test ride.
Thanks for the video. I'm looking to do the same thing. I assume there is some sort of throttle on the handle bar, right? Also, what is your top speed (with some pedaling) on a straightaway?
The bike goes 20 MPH under electric power. That's very common, as in a number of places, that's a speed limit for electric bicycles. There's a throttle on the right handlebar. It connects to the motor controller, and would be included if you bought a "kit".
this is really cool. how long does it last? also, i've got a few of those greenworks 80V batteries like these. I wonder if they make a hub motor and motor controller that would work with those 80V batteries? Great stuff.
Good job with the 3d printed mounts. I have 20 of these ryobi batteries used around the house in solar power side table mounted generators that I made. They power lights, tvs ceiling fans etc. I like your idea here and wanna make a ryobi 40v powered diy etrike. Can you tell me what the rated voltage of your hub motor and motor controller is? Will a 36v hub motor work? Or 48v using the 40v battery
@@user-fh1gu9jk2r upset? Or do you mean maybe that they discharge prematurely? So far no. I will most likely rebuild my 6ahr ryobis later with capacity lithium cells, using the older high discharge originals as spares for my 5ahr batteries. These I use for my yard tools.
GREAT Question! I couldn't tell you, because my bike doesn't have regenerative braking on it. Chris at the SerendipitySue RUclips channel has done a quite a few Ryobi battery videos. Watching some of his might give you a better idea. ruclips.net/video/ChC_vQpG3_M/видео.html
Works well overall. 500watt/36V hub motor. The battery features low-voltage cut-off and overcurrent protection. I'm not sure of the exact power the battery is rated for. I think the BMS current limiter may be 10A. If I accelerate too quickly, the battery sometimes cuts power. I just have to cycle power to it to reset it, but it occassionally nuissance trips. I also played around with running a second battery in parallel, and then that completely eliminates the problem. About 15 miles or so of range on the one battery. 3D printed mount is very solid.

Range?
I did 18 miles on the 5ah battery with mixed pedaling and motoring.
Very cool! Was wondering if such a thing was possible, and here you are doing it. Hopefully more uses for these type of battery packs can be found.
This is really cool. I’m looking forward to seeing distance, speed and all the specs. Nice work
Love it

@@BenjaminNelsonX yah, I thought about using two batteries in parallel. It’s definitely will increase range.
This is super cool. Would love to see Ryobi take this idea and run with it. An aftermarket Ebike Conversion kit from Ryobi would be super neat.
This is dope! 😍
Nice! But you need to paint it Ryobi green.
Does the 40V battery give out under acceleration due to some sort of current protection? I think I'm seeing this on my build.

Brilliant!
If you are buying a hub motor is it better to get one that expects 36V or one that expects 48V when you use the 40V from Ryobi?
36V.

An 80V battery would be great for a 72V system. Pretty powerful stuff at that voltage!
What kind of protections do the greenworks have built in?
Some brands rely on the tool to ensure the battery isn't over-discharged...
Is there anychance to purchase the battery mount holder ?

That is fantastic mileage.
