I am new to the forums and am looking for help with my first conversion. I have a 20" Mclane Reel mower that I pulled the old gas engine off and replaced with a 40v electric scooter motor. I have purchased multiple speed controllers to run this motor, however each controller has failed. Can anyone please direct me in the best option to make my setup compatible.
I am using a 80v 2.5 ah Kobalt Lith-Ion battery as my power source. I have disassembled an extra charging base that I am using as my battery holder. Below are links to the motor and controllers that I have purchased. Ultimately, I believe I will need to run this motor somewhere around 25% of power and I would like to be able to reverse the motor direction when needed to sharpen the blades.
This is the motor I purchased. https://www.amazon.com/gp/product/B073MY6CP5/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1
