Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 188 Small craft, in collaboration with the
European Committee for Standardization (CEN) Technical Committee CEN/TC 464, Small Craft, in accordance
with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This edition cancels and replaces the edition (ISO/TS 23625:2021), which has been technically revised.

Small craft — Lithium-ion batteries
1 Scope
This document provides requirements and recommendations for the selection and installation of lithium-
ion batteries for boats. It applies to lithium-ion batteries and battery systems with a capacity greater than
500 Wh used on small craft for providing power for general electrical loads and/or to electric propulsion
systems. It is primarily intended for manufacturers and battery installers.
WARNING — Lithium ion batteries used in direct current (DC) electrical systems on boats that
operate at potentials of 60 V or higher have additional safety requirements not addressed by this
standard. Refer to the battery manufacturer’s recommendations.
