Our business is built on two main foundations:

 

  1. 12 & 48v LifePo4 batteries 75, 150, 225, and 300A capacities


Our products are built from recycled Renault/Nissan motor vehicle batteries and come in 3 grades: lithium ion; lithium manganese, and LifePo4. All our housed for additional security in stainless steel containers and are complete with our own BMS.

 

  1. 48 & 96v Electric outboard motors of two types:

    1. simple 5 and 10hp designed for yacht tenders and small fishing boats

    2. oil cooled 20HP units designed for more rugged use.

So that we can offer complete solutions that we know work together, we also offer 
 

  • Solar panels

  • Hybrid controller inverters that we carefully match to your panels and batteries with the 220v capacity that you want to use aboard., and

  • Solar yacht hot water systems that use spare solar capacity to heat the water in your boiler.

What works & what doesn't

Lithium batteries are now the right answer to all battery needs everywhere. The cost per Ah is now less than that of AGM or gel lead/acid equivalents. They are also much lighter on a purely Ah basis. They can be charged from vehicle or boat alternators, solar panels; mains power via a charge controller; or a generator. It is vital to make sure that the charger is compatible with the batteries. Consult Us before making a decision.

Battery Capacity

The first critical question is what battery capacity is needed? That is decided by the speed and operating autonomy required. For instance a 20HP electric outboard will use 13.5KwH at full throttle, but only 4.5 at half throttle. Three hours autonomy needs at least 30Kw of battery power and more like 36Kw. Each battery weighs some 60Kgs, so 6 weigh 360Kgs. Add the 50Kgs of the motor and the installation weighs over 400Kgs - five average passengers!

Battery Charging

Lithium batteries with a suitable charge controller can be charged from the mains, solar panels, or a generator. Mains is fast and easy; good chargers start generators automatically but are not that "green" let alone needing to be housed somewhere; and for solar panels there is always the question of the space available and the fact that they need sunlight so are much less effective in winter. We do not recommend using your boat alternator for charging boat batteries. We advise the use of an alternator/lithium charge controller to avoid the risk of over-heating, or worse.

Charge Controllers

There are hybrid charge controller/inverters for 12, 24, and 48v batteries and 220v output capacities of 1, 3, and 5Kw. Most but not all support lithium batteries. We are distributors for the Chinese giant MUST SOLAR;

Electric propulsion,

Electric motors for inboard or outboard use are inexpensive and powerful. They are slightly more expensive than their internal combustion engine ("ICE") equivalents, but with more instant torque they provide the power at much lower revs.  They are also lighter. 

SUMMARY

Some boats are much better suited to electric power than others!
