The 2 Nm Battery Motor (WSERD30B 2/31) is a ground-breaking solution featuring an advanced coreless DC drive that is significantly more efficient and quieter than traditional battery motors. Powered by an internal rechargeable lithium battery, it provides approximately 12 months of use (based on 750 cycles) on a single charge. This motor is highly versatile, fitting tube sizes from 30mm to 50mm, and can lift blinds up to 10ft x 10ft. With intelligent internal charging management, it prevents overcharging and eliminates the need for unsightly external cables by plugging the ALDC charger directly into the motor head.
