LITHIUM BATTERIES: incendiary flavour of the month

23 Jan 2025 14:09 | Guy Nowell (Administrator)
MarDep have introduced some rather vague regulations for Lithium Ion batteries in Pleasure Vessels. Attached, below.

Members purchasing Li-Ion batteries with a combined rating of above 600Wh should ensure that the batteries, whether they are for propulsion or house use, are rated as IEC 62619 or IEC 62620.

Li-Ion batteries MUST have a battery management system to disconnect the batteries if they reach over-temperature, high/low voltage and charging/ discharging current limits. Batteries should be located away from hot areas, be securely fastened down, be away from water and have a battery disconnect service fitted.

A fire detection system should be fitted when Li-Ion batteries are in an enclosed compartment. Batteries should not be in a habitable space unless they can be vented outside the space.  More information can be found in ISO/TS 23625.
