Pacific Yacht Systems and Roton are your source for marine grade Lithium (LiFePO4) batteries and battery management systems

Lithium batteries have many advantages, including:

  • capacity - 80% useable (as compared to 50% for lead acid)
  • lifespan - on average 10x more lifetime power cycles
  • charging speed -  on average10x faster charging
  • weight - 70% lighter than lead acid
  • consistency - holds battery voltage evenly thru discharge


But be aware that "drop-in" lithium batteries are not really "drop-in" ...

There are several considerations to ensure an installation that is safe, and maximizes the life of your new batteries:

  • are your batteries managed by a BMS to avoid dangerous charge/discharge conditions?
  • is your battery charger suitable for the unique requirements of LiFePO4 batteries?
  • is your alternator's regulator set up for charging LiFePO4?
  • is your system managing overheat of your alternator?
  • is your alternator protected from damage during a BMS safety disconnect?
  • is your DC wiring correctly configured to ensure equal charge/discharge of the cells in your battery bank?
  • does your system allow for mixed battery chemistry (LiFePO4 for house, flooded/AGM for engine start?)
