Lithium Battery Systems

The installation and commissioning of lithium iron phosphate battery systems on board cruising yachts is a subject of great interest for offshore cruising as well as living aboard. Traditional lead-acid battery banks typically exhibit very poor life and performance in this type of service.

The articles published here have been extremely time-consuming to write, due to the volume of research and experimentation involved, but also because of the amount of time required to gain practical experience on board with this technology. It was also necessary to establish a small user base beyond the initial pilot project to obtain feedback and data originating from different energy usage patterns and observe those performing through winter and summer.
The absence of an acceptable and really adequate battery protection/management solution prompted the development of such hardware, which was then followed by extensive testing and validation in the field.

The objective here is providing all the information required for building and commissioning such a lithium house bank, starting from bare lithium battery cells. Completing this task will take a little longer as it is forever competing with other work, but I have now started publishing this material.

Building such systems is the most cost-effective pathway to embrace this new technology, but such installations must be carried out with a great deal of care and attention in order to deliver a good and safe long-term outcome.
