We have chosen the electric karts from the Swedish manufacturer Caroli.
Obviously, we chose electric karts for the environment. Then, to avoid exhaust fumes and noise of gasoline engines is something we got the bargain.
The karts have a strong engine of 14 horsepower. (To compare with 6-9 hp of gasolin karts.) Torque is 40 Nm which gives a rapid acceleration. Top speed is approximately 65km / h.
For us to be able to run with the power we need good batteries. So we use 16 pieces 60Ah Lithium-ion cells, 3.2 volts with a capacity of 3.1 kWh per kart.
Everyone who tried our karts have been pleasantly surprised - even the really hardcore racers .......
