For commercial operators and green boaters

A class of its own in lithium batteries for boats: 70% more energy density and 50% longer cycle life than typical lithium LiFePO4 batteries.

With the Power 48-5000, Torqeedo brings a new class of lithium batteries to the market. Based on automotive technology and BMW i battery modules, Power 48-5000 delivers industry-leading value with its combination of energy density, long service life, ISO standards compliance, and cost.

  • High-performance lithium battery 5.000 Wh
  • Rated voltage 44.4 V
  • Weight 36,5 kg
  • Including battery management system with integrated protection against overcharging, short circuit, deep discharge, polarity reversal, overheating and submersion
  • Waterproof to IP67

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 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.
