Marine Battery Systems
Reducing the environmental impact associated with pleasure craft and the maritime and river transport of goods has become a priority objective for the marine sector, which is increasingly focussed on power solutions that combine performance with sustainability.
Flash Battery lithium batteries provide crucial assistance for the green development of this sector through safe and efficient electrification solutions. In addition to silent operation and the removal of polluting emissions, the proprietary Flash Balancing System (BMS) electronic management system provides numerous benefits, delivering a high range and long service life, by constantly and comprehensively monitoring the battery pack.

The advantages of using Lithium Batteries for electric boats and other marine and nautical systems
The Flash Battery lithium batteries for electric and hybrid boats are lightweight, compact, and offer a long service life. The advanced BMS and tailor-made approach make Flash Battery the ideal partner for meeting the needs of a wide range of requirements in the marine sector, from sport fishing to environmentally friendly solutions for sailing in protected areas.
A custom lithium battery to meet the needs of your boat
Flash Battery develops custom lithium battery packs to meet the specific needs of every electric boat, beginning with an analysis of the real operating conditions. From the prototype to production, Flash Battery adds value by achieving the perfect match of battery and boat.
