After my experience with AI, I couldn't agree with you more. I know nothing and AI clearly steered me wrong. This whole thing started because I have 20v Dewalt batteries and I was tired of the battery on the Dump Truck ride-on dying in the middle of a ride. I wanted to have a full, spare battery in the trunk that we could swap out mid-ride. I purchased this DeWalt adaptor: https://www.amazon.com/dp/B0B4FS1NV1?ref_=ppx_hzod_title_dt_b_fed_asin_title_0_0 It worked fine for months. Only when one of the gears on the OEM motors sheared off, did I then embark on this harrowing exploration of upgrades leading to the OEM board frying. So that's where I'm at.
