I got the BMS reset. As @fixitbetter noted, a charger won't do as they won't turn on without some nominal voltage to prove that a battery is present. Catch-22.
I thought I'd post the process for amusement purposes. Can you guess from the picture?
Here, in part, is what the photo says...
No idea if this is of any interest but figured I'd come back and update the record here.
I simplified my original hookup today. The one above was my "Murphy build": worked 100% through all my testing right up until I got all the skins back on the mower and a full charge in the belly of the new...
I will do that, likely this weekend.
The mower is still apart while I await a very, very delayed Amazon order, finally arriving sometime today. In the meantime I tested my idea with some spare parts I've got here and it seems to work. The basics involve another relay (I ordered this one) and...
Finally enough stuff came together that I was able to complete this seemingly endless project. The below is what I've wired up:
The idea of the circuit above is to use the capacitors in the mower to delay enabling a relay turning on and off the contactor in the mower. It seems that the key...
I just got mine today and installed it. Easy-peasy. Used some Gorilla tape and a double layer of cellular PVC trim. Let's see how long before I regret that bad decision. ;). Like others it won't "start" due to the need of a bypass so later this I am week I am going to try a quickie...
Thanks for the reference, nice unit. Sadly their website is not cooperating on telling me the shipping charge so I cannot yet see just how many more dollars it is.
Also it may not fit. I notice that it is taller than the Chins at 9.125" (and I don't know how much the posts on top would add)...
Thanks, odd design that it can lock you out of the battery. I'll call Signature Solar tomorrow to see if they can help me with the battery.
My app shows the following:
I worked on this a bit today but it has not gone well. I did but one test and the mower cycled on and off a couple of times and then nothing. The BMS must have cut out again. The Bluetooth app show the battery is in "Protect" mode and there is zero volts across the battery terminals. I've...
I should think that your choices should work, but am new to this myself and far from an expert. Your location says "NY" so I don't know how you store your mower in the winter but be careful not to ever charge these batteries when the temp. dips below freezing. Doing so will likely ruin them...
Like many others, I joined this forum as a result of this thread (via a link on a Home Depot review). I just started a third season of mowing with my Ryobi 75AH ZTF mower and it only did 1/2 the lawn. With two more charges it finished the mow and subsequently got worse. I can now get 5, maybe...
Thanks, I was hoping for something like that when I hooked up the charger. I'm still on the original charger, so maybe something wrong with using that?
