In the process of returning a 24volt dune buggy for that exact reason my man - so yes. Popped & smoked
If they make something that will grenade the second someone adds 1 more lb of boost, then they didnt make it right. Its called safeguards. Mediocre ratchet straps dont break at 501lbs of force. Tires dont burst at 51lbs of air. TRXs dont implode at 12lbs of boost and dont fall apart at 1101lbs of payload. And if they do, that’s on them to remedy the problem. End users are expected to be stupid, careless, etc. and its the manufacturer’s responsibility to bake a reasonable degree of safety/fluff into the product.
PSA for all dads out there = 12volt electric ride-on cars are good with an 18v ryobi upgrade. 24v cars are NOT good with a 40v upgrade - things will melt & smoke!
