Various Lithium-Ion battery systems have been developed for the REMUS series of autonomous underwater vehicles. Ranging is size from 1 to 16 kWh, these systems are built from arrays of smaller batteries. Each component battery provides 250 to 750 Wh, and is equipped with extensive protection, charge, and data functions.

: 7 kWh battery, made from 16, 450 Wh modules, as used in the Tunnel Inspection Vehicle that took 180,000 photographs inside a 70 kilometer long under ground aqueduct for the City of New York (2003). (Ned Forrester)

: 5.5 kWh battery tray for REMUS-600 (12.75 inch diameter) vehicle. One to three trays can be installed, depending on mission requirements and payload. (Ned Forrester)

: Sixteen REMUS-6000 battery modules assembled into two housings. 16 REMUS-6000 battery modules assembled with titanium end caps and electrical penetration for installation into two pressure housings (not shown). (Ned Forrester)

: 750 Wh battery module for REMUS-6000 vehicle. 8 of these are installed in a 1 cm thick titanium housing. Two housings power the REMUS-6000 (SAMS) vehicle to depths of 6000 meters. (Ned Forrester)
