Valence U-Charge Depth of Discharge

Valence is responding to demand for power and reliability not found with other Marine Battery Manufacturers:

Valence marine battery power enables a drive system exceeding core requirements of marine battery manufacturers, and ensuring significant benefits over traditional lead acid type batteries and other lithium chemistry.

Used on open waters, marine drive systems need to be intrinsically reliable. Leading innovation among marine battery manufacturers, Valence’s Lithium Iron Magnesium Phosphate modules offer a reliable power source due to LiFeMgPO4’s excellent cycle life, safety, and battery management system.

Case Study: Utility Boat Manufacturer

Product: U27-36XP Valence U-Charge® 38.6V, 46Ah Lithium Iron Magnesium

Phosphate intelligent battery module assembled into a system

Working with a leading utility tugboat manufacturer, Valence was able to provide the right mix of energy and power for their new hybrid vessel design. Following the successful testing of the Valence modules, Valence’s support engineers assisted with the configuration of 2 systems each containing 120 kWh to be housed in the boat to supply energy to hotel loads as well as propulsion. Both battery banks can be charged from a single charger but can operate independently of each other. The system should provide average fuel savings between 10% and 30% and cut local emissions by 20 to 60%.
