Here’s my breakdown of this beta launch kart… taken mostly from the video.
X30 - I am going to assume this refers to the 125cc Euro Senior X30. The specs shown are the IAME website claim:
22.37 kW peak power
19.5 Nm peak torque
EMRAX 188 air cooled
Axial flux external rotor - difficult to cool and mount. To that point I found this:
“For air cooled motors the air speed must be 25 m/s at max air temp 25ºC”
Assuming this is the low voltage (110v) version…
52/23 kW peak/continuous power
90/40 Nm peak/continuous torque
Appears to be using a 428 chain and sprocket
Pricing is hard to find, estimate $3500
Unknown, possibly a Bamocar D3
It is mounted underneath the front cowling and appears to be liquid cooled - although I don’t see a radiator. Possibly using a cool box?
Pricing is hard to find, estimate $3000
Dual - air cooled
I would wire them in series. Best guess is about 3.5 kWh usable each, for 7 kWh of power (per swap).
Estimated minimum cost is $3200 per battery (with internal BMS).
?? Possibly internal to each battery based on the connections shown.
Best guess cost with 4 batteries and charger - around $21,000
