Ordering information

• Equipment included: Power 48-5000 high-performance lithium battery 5,000 Wh (44.4 V), cable for communication with TQ- CAN
• Warranty: 2 years for non-commercial use

• Important Information

  • Gateway TQ-Bus/TQ-Can and On/Off Switch for Power 48-5000

  • At the start of production for the Power 48-5000, Cruise 4.0 and 10.0 motors will be compatible with the new battery
  • Power 48-5000 can be operated and switched on and off with the switch included in the scope of delivery of the new throttles part no. 1949-00,1950-00, 1951-00 and 1952-00. The gateway is also included in the scope of delivery of the new throttles
  • A separate Gateway including the On/Off-Switch (part no. 2217-00) is required, if Power 48-5000 is used with standard Cruise models TQ-Bus and their standard tillers and throttles
  • A separate On/Off-Switch (part no. 2215-00) is required, if Power 48-5000 is used with non Torqeedo consumers
