I did a short clip while doing the 4x volt meter video, that never made the final cut. I'll look at doing a small video on the Relay Module/Control Board. I'm glad my videos were helpful for you and your neighbor. It's so satisfying to breathe new life into such an expensive piece of equipment, without a dealer.
I would find it very interesting if you made a video where you walked through exactly what is happening with the relay module. Love your videos and I used them as sort of a guide to help a good friend of mine convert his mower. He has the exact same mower as yours.

Hi Mr Rob, one more question about 6 wire ribbon wire connectors. All five wires are connected to the black wire , am I correctly understood? Since in the diagram it tapering down and fades away merging to the black wire. Please clarify. Thanks regards. Ben.
Yes, it's a 6p connector/ribbon that controls the relay board. And yes, 5 of those wires are connected together to a single ground wire. The VOC terminal is the 12v positive from battery #4 to power the relay board and power all the relays. The GND terminal is the 12v ground from battery #4 to ground the board itself. The 4 wires in the middle are the triggers/controls for the 4 relays. When you ground each of these 4 wires, it triggers each relay. In this application, I didn't need to control the relays individually. I wanted to trigger all 4 relays at the same time, so those 4 wires are connected together to battery #4 ground. At least that's the amateur logic that I used. Rob
May I ask why you went with 4-12v 100Ah batteries that require balancing and monitoring verses 1 large 48 v 100Ah battery? I understand that there would be a bit of tray modification to accommodate the single battery. Thanks
In hindsight, I may have reconsidered. But when I started, I was learning way-more about Lithium than I ever thought I would, and I wanted to keep it as simple as possible. And it was simple; The battery swap was very simple doing 4 for 4. it wasn't until I was reading the Chins Owner's Manual, I started to wonder about balancing/monitoring. And that got me wondering about how well the batteries would stay balanced. And then I figured out this "cheap" plan to get the individual voltages...and then figured that I could add the ports to do individual battery charging. So far, the batteries do stay within 0.2v of each other and I've had no problem mowing or doing the fall clean-ups. So, adding the 4x gages was certainly an interesting project and I'm glad I did it, but not really necessary.
Thanks for your reply. I will probably upgrade in the early spring as we approach winter. Your videos and commentary are excellent and very helpful for those of us with these machines. I was wondering if you had come up with an idea how to keep the batteries warm in the winter as I'm just a state south of you and keep it in an unheated storage barn. It's too bad that Ryobi placed the batteries that they did with the mowers. Mine lasted less than a total of 25 run hours. @@robertveldman1901

THANK YOU SIR !!!!!!
I would like more details on wiring. The wiring sketch shows positive of one meter connected to negative of next meter as if they are in series. It's a bit confusing for me .please elaborate more about wiring. Thanks so much for regards, Suresh.
Yes, it does look confusing to me too. But that's kinda the same thing that you do to the batteries; neg to pos. Look at the battery schematic at 27:30. You can prove the concept by using your hand held volt meter. Touch 1P and 1N = 13v. That makes sense for battery 1. Touch 1P and 2P = 13v. Yes, touching two positive terminals is the same 13v of battery 1. Now try 2P and 2N = 13v. That makes sense for battery 2. Then 1N and 3P = 13v. That's strange, but it is same battery voltage as battery 2.
Thanks for your kind reply. My confusion is not at battery terminals. I was talking near Voltmeter connections. One positive seems to be connected to the negative of the next voltmeter and so on. It looks like a series connections . How do you connect voltmeter positive and negative wires? Sorry to bother you just learning. Regards
@@ben-xc9tq I understand your confusion. Myself, I know just enough about electrical to be dangerous. The volt gages are kinda wired in series, but you have to visualize that each volt gage is in fact wired to each battery. Whether the common pos/neg connection is at the battery, or at the gage (like I did)... it doesn't matter. The best thing to do is to do a bench test; actually connect up a couple batteries in series, and use a volt meter to simulate the volt gages.

I AGREE ... STEP BY STEP
Rob, I took your advice and added same but, in my opinion, a better outcome. Trying to figure out how to send a photo of my installation.
No kidding! I think you're the first to actual admit to trying this! And it worked for you?
Send photo to my gmail acct; rveldmangoog@
Do you have links to where you purchased the voltage meters and charging ports?
