Charging Marine Lithium Battery Banks
This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. Lithium iron phosphate (LiFePO4) battery banks are quite different from lead-acid batteries and this is most apparent when it comes to […]
Engine Reliability: A Look at the Volvo Penta MDI Black Box
In this article, we have a look at the Volvo Penta MDI electronic black box while relocating it off the side of a Volvo Penta D2-40B engine in order to protect it from the heat and vibrations. IF YOU OWN A FAILED MDI BOX, PLEASE CONSIDER SENDING US PHOTOS OF THE INSIDE AFTER LIFTING THE […]
Protection and Management of Marine Lithium Battery Banks
This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. This article discusses the protection of lithium battery banks in the context of marine installations. A previous article detailed the design […]
Electrical Design For a Marine Lithium Battery Bank
This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. Integrating a lithium battery bank on board a vessel introduces a few additional constraints and challenges that don’t exist with lead-acid […]
Assembling a Lithium Iron Phosphate Marine House Bank
This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. Here, we detail the hands-on process of building a lithium battery bank from individual single prismatic cells. There is more to […]
Practical Characteristics of Lithium Iron Phosphate Battery Cells
This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. Batteries are about voltage, current and capacity first and foremost. This article discusses the performance characteristics of lithium iron phosphate cells […]
Lithium Battery Banks – Fundamentals
This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. Hundreds, if not more, of research papers have been published about lithium batteries, as well as numerous books. Still, a lot […]
From Lead-Acid to Lithium: New Battery Technology for Power on Board
This article is part of a series dealing with building best-in-class lithium battery systems from bare cells, primarily for marine use, but a lot of this material finds relevance for low-voltage off-grid systems as well. The development and mass-manufacturing in recent years of large-size lithium-ion battery cells for electric vehicles and grid-tied electricity storage has made […]
LED Lighting on Board
One of the largest technological differences between fitting out the sloop Yarra in the early 1990s and launching the Nordkyn design in 2010 was the transition from halogen to LED lighting. The performance and quality of LED lights was evolving so rapidly that I literally deferred purchasing light fittings until the last moment.The following sums […]
