I had success putting a 40v lipo pack into my 24v scooter, and just wiring a switch to it (would've blown the speed controller). Gotta be careful running it uphill, and, the motor would eventually really not appreciate the heat, but, it's doable.
To make a DC motor spin faster you just give it more voltage. This makes it draw more current, spin faster, and accumulate more heat.
The speed controller would need to be upgraded probably, if you wanted to continue to have variable speed.
You'd need to upgrade the charger to charge to the correct voltage.
Cutting some lines carefully into the motor case, or hoseclamping some heatsink to it, or adding a cheap trio of 2" computer fans to it in series would help it from overheating as badly.
But at that point you're just re-using the frame and sort of motor.
For that matter, you could replace the motor too.
You could keep the same motor and change the motor pulley size, this will change the speed it spins.
You could keep the same motor and increase the tire size.
Neither of those two makes the motor more powerful, but it will force the motor spinning at a given speed to make the tire cover more ground in a rotation. This will demand more amps from the controller and battery and motor.
I also did this to a drift cart, and after several adults aggressively raced in in a 100lb max children's vehicle, the motor overheated enough to where it caught on fire.
There are a large variety of solutions depending on your budget vs. bullsh!t continuum.
