"A list of impossible specs at a price that suggests a scam."
'Peak 4000W Power' is a theoretical maximum the motors might hit for a moment before overheating; the real-world sustainable power will be a small fraction of that, assuming the electronics don't fail first.
This product's specifications and price do not align with a real, safe product. No one should purchase this based on the provided information, as it indicates a high probability of being a fraudulent listing or an extremely dangerous item.
Anyone who values their money or physical safety. The listed price is far too low to cover the cost of safe, functional components for a battery and motor system of this claimed power.
