I use EV's because they cost me about 1.5 cents per mile to drive at my current (pun intended) electric rates vs 15 cents a mile for a fuel efficient gas car right now (10 cents a mile for gas one presidential term ago), and for the high performance. My "slow" EV does zero to 60 in 6 seconds...

For those more technically minded here is the test procedure and resulting discharge profile over the 17.5 hours: At the start of my test I plugged in the fridge to the wall to cool it down, and froze 16 half liter bottles of water and put them in the fridge section… this is the same thing I...

Hey guys, Just an update on the "use the old cells as a backup supply" idea. Due to Hurricane season we had a 24 hour power outage at my new home, and I used my Bolt EV as a power source for the essential loads in my house (side by side Fridge / Freezer, modem, router, fan, laptops and cell...

I don't have high expectations for this attempt at restoration, I just figure "why not try"? If I can restore the weaker cells and use them as a home backup in case of power outage (rare here, but they do happen) it is better than just junking them. The batteries don't self discharge, and they...

$1000 in batteries (for me, upgraded from 75 ah to 100 ah) is a lot less than $2,700 for a new electric riding mower... and that is for a 50 ah version. If you can figure out and repair the accelerator problem it is well worth keeping the mower you have now. Now, if you are itching to get a...

Most batteries are not worth the effort of trying to revive. A thousand dollar battery pack with one good unit, one OK unit, and two bad units is worth the attempt. A desk top DC power supply with variable voltage / variable current capability and a built in voltage ramping capability to ramp...

Perhaps a desulfator used from the beginning will prevent sulfate buildup on cell plates, but after weeks of testing a desulfator / charger on the two weak 75 ah cells taken out of my Ryobi 480e (replaced all cells with 100 ah) there was zero improvement. I have purchased a lab power supply...

Off topic: When I had a problem I could not find any help for troubleshooting or repair, can you link to the troubleshooting guide? Thanks, Keith

It is about charge cycles and heat. One of the things I like about EGO equipment is that the battery cells within the battery pack are encased in a phase changing substance that absorbes the heat out of the cells as it melts (undergoes phase change) from solid to liquid so the battery cells are...

Wow, the new 100 ah cells are monsters compared to the little baby 75 ah cells! Using my bathroom scale the old 75 ah cells are 50 lbs. each, so 200 lbs for the whole pack... the new 100 ah cells had a shipping weight of 76 lbs, call it 75 lbs without the packing material and you get 300 lbs...

I found my problem, either when I pulled the battery tray out, or slid it in after individually charging each cell I snagged one of the cables that goes above the battery pack and un-plugged it. After plugging that in the mower worked and mowed!!! But it still had pathetic run time :( Less...

Anyone have Dingo-J's repair manual that they can e-mail me? I messaged him, but he hasn't been on the board in the last 5 months, so I am not hopeful about getting it from him. My issue is different than the common one in this thread, but the repair manual would be a great help. Keith

And I wonder why people don't read a post before they reply to it. I am pretty sure you are giving generic advice most of which was covered in my original post, and some of the advice seems directed at a gasoline or Diesel powered mower rather than an Electric riding mower. The lights (that...

This isn't a "it wont move" or "the blades wont turn" situation, when the key is turned nothing happens. No relay click, no meter response, no nothing. I load tested the batteries when I had them separated for charging. My bad for not mentioning that I had load tested the cells. Keith

Hey guys, this is a long story. I went to use my Ryobi electric riding mower for the first time this spring and found it DOA... initial investigation found that the outlet it was plugged into had failed and was providing no power, no idea how long the outlet was dead... may have been all winter...
