”louis rossman” (whoever that is?)
Rossman is a Youtuber, Electrical repair man. He is somewhat skilled in electronics, has a youtube channel, and a big following. I have watched a few of his vieos, and do not really like the dialog. The dialog is boring to me, with my skill set. Caters to limited repair knowledge, but he has carved out a spot in the world of electronic repair. I do not think he has any classic engineering training nor classic electronic engineering training. I do not think he is certified or licensed to engineer.
He made a vid when he caught some ebike batteries on fire, accidental, and blamed it practically entirely on the manufacturer of the battery. I do not go to YT to listen to things I already know, to contribute to ones view count. However, he seems to be jumping very far so the blame does not fall on him, the person who modified the circuits, and places blame solely on the maker of the battery.

I also go over business concepts & philosophy that will be important to running & maintaining a sustainable, profitable business.

This is the circuit he used that burned. Alot of things he says does not make sense, and are blaming the manufacturer, and not allowing the blame to meet his own poor designing .He says "Hall sensor board" when it is really the entire "controller PWM and inverter bridges" , referring to the BBSHD... Items like that lead me to believe he is kinda " flying by the seat of his pants" when he makes assertion ..... He thinks a SammySung 30Q 18650 is " really high output" {sic} He thinks an ebike battery is " a large high capacity battery" {sic} .. Lol. He thinks he did not " get what I paid for" {sic} when he made stupid modifications with inherently unnecessary complication. He did something that is not condoned, and missed in translation, for any of many reasons. He thinks he knows everything. He just trashes UPP and recommends the EM3EV. I kind of think it is a market campaign.
At least I know, I do not know everything.
