eh, ci deve essere una bella differenza:
xl:
●Input voltage

C11.1-22.2V 3-6cell Li-Po
●
Max continuous current:70A/85A(60sec)
●Max output power:Approx. 1600W/2000W(60sec)
●KV value:1650KV
The KV value is similar to 600L motor, but the performance is much power under 3D flying, features continuously strong torque.

Input voltage: DC25.2V 6cell Li-Po
●
Max continuous current: 65A
●Max output power:1500W(prox.)
●KV value:1620KV
