Hi, I see in all the ads and promotional material that the TC 50 has a 1500W motor.

Printed on the VIN plate on the headstock "1,9kW".

Is this peculiar to Spain?

Strange. Here in Belgium they advertise with 3K power ?

60vX30aH = 1800kW
3k can't be possible with a single soco battery.

Not possible but the motor can handle 3000w maybe?

Yep I was talking about the Bosch engine. It's max 3000w.

we have one Spanish TC (from Sumco), "1500 W", 

and another German TC, "3000 W",

they are identical. Both have 1.9 kW (mechanic) rated power, both behave exactly the same. Both have 115 Nm maximum measured torque, 24% max hill climbing power. The 3000 W is a marketing trick: Connect a 3 kW motor to a 40A/60V/2.4 kW (electric input) controller. The controller has ~10% loss, the motor has ~10% loss, so you get 1.9 kW.

(maybe the original design was 45A/3kW - the BMS and the Controller are capable of 45A but software limited... 67V * 45A = 3 kW, at 45A the motor could develop 130 Nm torque as initially claimed)
