How fast can MJX Hyper Go 10210 actually go? Can the stock ESC run 3S batteries directly?

MJX Hyper Go 10210 is extremely fast. With the stock 2S battery, its top speed is about 50–55 km/h, perfect for daily street running.
The original 45A (or higher) brushless ESC fully supports 3S batteries.

When upgraded to a 3S battery, the top speed can easily exceed 80 km/h, and the car will pull wheelies instantly when taking off.
