Marine battery systems, less is more

A common misconception surrounding LTO-based marine battery systems is that they are heavier and require more space than alternative solutions. This perception largely stems from evaluating batteries at cell level, rather than at system level. When assessed from a system perspective, LTO chemistry can in fact enable battery systems that are both smaller and lighter.
