Advantages / disadvantages
Acceleration is usually better than thermic model and the speed is sufficient for use on most kart circuits. Torque in electric motors are greater than that of the gas engine. They are ideal for quick take offs and off road climbing.
Electric go-karts are low maintenance, requiring only that the lead-acid batteries of the cars be plugged into an array of chargers after each run. Since they are pollution-free and emit no smoke, the racetracks can be indoors in controlled environments. Most fully charged electric karts can run a maximum of 20 minutes before performance is affected. An expensive alternative is the use of Lithium iron phosphate LiPO4 lithium batteries. They last much longer and carry more power per pound than lead acid batteries.
Electric power Go-Karts do not have hot engines or a tank full of gas which can prove to be safer in an accident.
Batteries are still very expensive and the autonomy is not that good. However, charging can be achieved in about 30 minutes and it is possible to swap batteries.
The ERDF Masters Kart racing event took place at the Paris-Bercy Arena in Paris, France in December 2011. Drivers from different auto racing series such as Formula 1, GP2 Series, WRC, DTM, IndyCar or kart racing got to compete with electric karts powered by a 40 hp brushless type electric motor.
There are a few other events for electric karts such as e-Kart, a university challenge, also in France.
In the US, the Red Line Oil Karting Championship of Northern California started hosting in 2013 a field of Ekarts (Category V, Group 2, Class 1) competing for the Rattlesnake Electric Sport Championship. Most weekends, lap times were within less than a second of the fastest laps, with reliabity much better than their gas cousins.
In Canada, the G-Zero Championship Racing Series is set to start racing on temporary city street circuits in 2016. The G-Zero series uses all-electric zero-emissions karts built by EVC Racing of Indianapolis IN featuring a blend of parts used in motorcycle racing and new innovative battery technology.
Since 2006, an annual electric karting challenge is organized by associations and e-Kart. This Challenge brings together manufacturers, schools, academic institutions (electrical engineering). This competition is played with machines expanding from 10 to 67 kilowatts, it takes place over three days and includes many tests (endurance 4 hours, best lap times, acceleration from stop over a distance of 50 meters, 10-minute races ...).
Latvia, World's First
In 2015, Latvian company Blue Shock Race launched new technology type electric karts. BSR2017 Blue Shock Race kart is first kart in world, which have changeable battery with small, extremely effective lithium battery pack, with one charge can drive 10-15 min. BSR2017 kart is most competitive kart in rental kart sector right now. 
This year BSR launched World's first national electric kart championship in Latvia supported by LMT Autosports Academy and 10 technical schools in Latvia.
it was launched in 1. May 2018 in Latvia, Kandava with 13 pilots.
After Latvian national electric kart championship stage 4 in Kandava Latvian company Blue Shock Race launched new electric sports kart for professionals. This kart are capable to compete with KZ2 division karts. In Latvia have TeK Open class where is allowed to race with 25kW karts and in 2019 will be more electric kart divisions.
