Lithium Ion Batteries

Don’t get it wrong – use a professional

The installation of lithium ion batteries and battery systems should be carried out by competent persons, and to suitable industry standards.

Only use the right kit and read the instructions completely

Specific marine lithium ion batteries and electrical system components should be used, they are designed for the change in risk associated with installation in a marine environment.

Make sure they are stored correctly in accordance with the manufacturer’s instructions

Lithium-ion batteries should be installed and/or stored in a well-ventilated, dry area and should be away from direct sunlight, heat and water. They must also be protected from vibration. All battery system design should be done in a way that ensures all installed lithium ion batteries are kept within the battery manufacturers specified safe operating limits.

Don’t mix and match

Different battery chemistries should not be connected in parallel or in series. This is because the load characteristics and capabilities of these batteries are drastically different which can lead to safety issues.

Have the right fire protection system

Traditional firefighting systems may not work on lithium ion battery fires. You should arrange for a risk assessment by a competent professional and follow their recommendations for appropriate fire protection and firefighting systems to be installed for your particular vessel.

Remove damaged batteries immediately

Any batteries showing any form of damage must be placed in a fire proof container and removed from the vessel once identified at the earliest opportunity, be they vessel systems or toys and accessories. Damaged lithium ion batteries are known to combust.

Disconnect when finished charging

Only use manufacturers’ charging devices and do not leave equipment chargers on and charging when away from the vessel and once the equipment is charged, switch it off.

Tell your insurer

If you install lithium ion batteries and/or battery systems on your vessel you must tell your insurer, or risk being left uninsured in the event of an incident.
