Been following for a while

Hi All, I have been following for a while. Not sure if I have posted yet. I have converted a Grasshopper lawnmower from gas to electric, with the help of a couple friends. I kept the hydrostat and have one motor with a speed control running that and a second motor driving the PTO which runs the mower deck.

I have 15 CALB 180 Amphr batteries. I have also used a snowblower on this setup, but not as effectively.

We also have a 2012 Prius Plug-in, which I realize is not a full electric vehicle, but we drive about 28% on electric over 50,000 total miles.
