Batteries play an important role on all vessels, including yachts. Batteries are the heart of any DC electrical system. Your motor yacht’s batteries will store the electrical power from your yacht’s generators or shore-based charging system, for “on demand” use as needed. Most vessels have a traditional 12 volt system that is made up of one or more “banks” of multiple batteries. The electrical system of larger yachts may have 24 or 32 volt systems.

Marine batteries on your yacht can provide electrical power to everything from starting your engines, to the power for lights, computers, and entertainment systems, to alternative “get home propulsion ” systems.

With marine batteries being so critical to a yacht’s or other large commercial ship’s safe operation, there has been ongoing research and development into creating marine battery systems that can last longer, as well as provide more efficient power. It was only a matter of time before the kinds of battery technologies being successfully used in hybrid and all electric autos, “jumped ship,” to marine applications.

Recently, BMW announced that its very popular “i” battery technology that is used in such cars as the BMW i3 is being used for marine applications. The automaker’s supplier of i-batteries, Torqeedo, has entered into agreement with BMW to provide the high-efficiency batteries for “motor boats, sailing yachts, and commercial marine applications such as water taxis.”

In a statement to the press, the German based battery maker said, “The BMW i3 battery has been adapted to work flawlessly with Deep Blue, Torqeedo’s most powerful solution for inboard, outboard and hybrid systems up to 160 HP.”

In that same company press release, Christoph Ballin, Co-Founder and CEO of Torqeedo, said, “We have made state-of-the-art automotive battery technology available for boats by offering BMW i high-capacity batteries via a recently signed supplier agreement. The first boats equipped with BMW i batteries are already in operation or are close to completion.”

Alexander Kotouc, Head of Product Management BMW i, added, “The selection of BMW i high-capacity energy storage for Torqeedo‘s Deep Blue drive system is further proof that performance, innovation and sustainability are not mutually exclusive. The successful adaptation of state-of-the-art automotive technology to the water is a testament to the comprehensive development priorities of BMW i.”

Innovation in Marine Batteries

Innovation in marine batteries such as adapting BMWi technology for watercraft, is important, since the performance and life expectancy of the batteries used on yachts or other vessels is entirely based on how often they can be charged, depleted, and recharged. That is known as the battery’s “lifecycle.” Anything that can extend a battery’s lifecycle is desirable, particularly to a company that may operate a fleet of commercial ships, or the owner of a large luxury motor yacht.

More Power to You

Regardless of the type of batteries you have aboard your luxury motor yacht, FYM’s On Demand Yachting Solution gives “more power to you.”

Signing up for the program means your yacht will always be carefully monitored and well maintained for any issues with batteries, generators or any part of the electrical system. Should your battery system need upgrading or retrofitting, our skilled marine engineers, will be the first to know it, and you can be confident they will make the right recommendations for your yacht and needs. And, you will be able to monitor the entire process through your own proprietary On Demand dashboard!


Operating a motor yacht can be costly. You can reduce your expenses, and avoid costly repairs by keeping her well maintained. On Demand yachting from FYM can help.
