Yes I did, but I’m about to post a bad picture.Has anyone completed this conversion on non-zero turn model?
Bummer.No idea what happened.
Geez. But it ran fine on this model? Did you torque the terminals to spec?No idea what happened. Had been mowing for about 1h, stopped to feed my dog, came back out and was on it 10-15 more minutes when I looked at the bms app and saw way effed up numbers. Was going to get off to see if a monitor wire came off when it started smoking then poof some flames. Didn’t completely go up but this battery pack is pretty much effed. So sad. Not sure what happened. Will look tomorrow after it has tonight to cool off. App is still communicating so the bms appears ok for now. Never drew more than 91 amps. So bummed

I have a couple of extra commercial 60" Xmark zero turn mowers with bad or questionable engines, but the machines are solid otherwise. I don't have the time to reinvent the wheel to try converting them over to all electric
Being able to pick your bms is a huge plus imo. I’m going with the electrodacus once I have to change out batteries. I have one in my van and it’s honestly perfect for me.Hello all thanks for all the infomation. This blog help persuaded me to get the Ryobi 54in 48v, I was on the fence because of the SLA batteries. Now I got a plan to convert it lifepo4. Should arrive on Apr 9 and converted to lithium that weekend. My question is the price of prismatic cell are crazy right now. I am looking and the price will be around 1200-2000 for 16 raw cells, or I can get drop in for around 1400-1600. Is there any advantages to diy my battery vs drop in from good old Amazon? Also if any one has a US raw cell seller that got good prices please share.
I don't know about the Calb cells but the cells I used were 7.9 in high and by the time you added a bit of space for lugs it was a very close vertical fit. My box external dimensions are 8.7 high, 14.1 wide and 20 in long. I had no clearance on the width - just fitted, and almost no clearance on the top after adding a thin acrylic sheet. There was a lot of unused length though.I am looking at calb cells from Battery EVO. Are Calb cells taller that normal prismatic and can anyone tell me if they will fit in the area the old sla battery are, or can I get 2x https://signaturesolar.com/eg4-8-cell-pack-lithium-cells-25-6v-100ah/ and fix sideby side a better option?
Not me, should have thought of that. Most lock nuts are stainless steel, which worry me might significantly reduce conductivity between posts and bus bars. Found these aluminum ones, a bit pricy but might just get them: https://www.amazon.com/Flanged-Nylock-Self-lock-Aluminum-Silver/dp/B07K5CJZKH.So, high vibration application - you guys are using Nylock nuts right?
And possibly braided interconnects instead of rigid bus bars? Depending on how badly your bank is bouncing / allowing for movement...
Me neither, but this is a great idea. I’m going to order these. Anyone have a line on some high gauge m6 ring terminal braided interconnects for cheap, or do I just need to bite the bullet and buy a hydraulic crimper and build them myself?Not

Thanks for the tip. So you don't think hitting the original torque spec using a torque wrench is sufficient? I suppose that might make it slightly under-torqued on the threads which I thought would be a safe bet.Just be careful with Nylock nuts if you have never used them before so you don't over-torque.
