When most people think of bumper cars, they think of the cars that take their power from overhead wires. These bumper cars are used at big amusement parks, but the installations require a lot of space and have a relatively long setup time. While they can be used at traveling fairs, they are less common than other, more portable attractions.
Battery powered bumper cars are far more flexible and much more convenient. The engines are powered by batteries inside the car, which are charged overnight. The bumper cars can drive in arenas which can be erected in a very short space of time, and the entire attraction is easier to move and manage, not even needing to be near a generator.
The one downside is that there is the risk of the bumper cars running out of power while they are in use. However, in most cases this is unlikely to happen if the cars are tested carefully before being used and the batteries are charged overnight. The cars do not need a lot of power - assuming that they will mostly be ridden by small, young people, they do not carry a lot of weight. In addition, they do not move very fast.
Battery powered bumper cars are safe and generally reliable. There will always be one or two bad batteries that discharge quickly, but the cars can easily be swapped out should this happen.
