Are Lithium-ion (Li-ion), LiFePO4 or Lithium batteries a good solution for thruster battery banks?1.9.2022
Not necessarily. These systems typically come with a Battery Management System (BMS) that will disconnect the thruster in case of any issue with the battery.
Can I use LiFePO4, Lithium or Lithium-ion batteries for my thrusters?1.9.2022
Yes, you can, but not without taking some precautions. Sleipner produces two product lines of thrusters that will work well with high-capacity batteries and one product line which should be used with caution in combination with LiFePO4, Lithium, Li-ion, or similar batteries, which may be capable of delivering higher voltage under load than traditional batteries (such as lead-acid, AGM, gel or similar).
What is the S-Link™ control system?2.9.2022
S-Link™ is a CAN-based control system used for communication between Sleipner products installed on a vessel. The system uses backbone cables as a common power and communication bus with separate spur cables to each connected unit.
What happens if I connect a Lithium, Li-ion or similar battery to my on/off DC thruster?2.9.2022
A Lithium or Li-ion battery may maintain a significantly higher voltage and higher current under load than a lead-acid, gel, or AGM battery.
Why does Sleipner declare thrust at 10.5 volts whereas others state thrust at 12 volts?1.9.2022
Unlike most thruster manufacturers, Sleipner bases its products' thrust (kgf) on a realistic, achievable voltage in real-life conditions rather than on theoretical thrust measured under ideal laboratory conditions.
My boat has Lithium batteries. Must I replace them?2.9.2022
If you have Lithium batteries powering your thrusters, the best advice we can give you is to check the actual voltage measured on the thrusters during operation.
Can the thruster cause the BMS to disconnect the batteries2.9.2022
Yes. Thrusters are heavy consumers, and they may create sudden peaks in current draw, which again may cause the BMS to disconnect the batteries if the thruster draws more current than allowed. If this happens in the middle of a maneuver, you would be left without thrusters and may lose control of the boat.
What is the recommended battery bank for thrusters?2.9.2022
Sleipner recommends that the thrusters are connected to a battery bank that is not protected by a Battery Management System (BMS).
Thruster operation and troubleshooting
My electric thruster does not operate?2.9.2022
There can be several reasons why a thruster fails to operate, but before contacting a service point, we suggest you check the following:
My thruster control panel will not switch on?2.9.2022
You must simultaneously press both ON buttons to activate the control panel. If your control panel still doesn't switch on, please check if there is electrical power available to the control panel.
I don't get enough power from my thruster - what can be the reason?5.9.2022
The most common reasons for not getting enough power out of your thrusters are:
How to reduce noise from your bow thruster8.6.2021
Does your bow thruster make a lot of noise? Whether there's been a lot of noise from the day it was installed, or if the noise level has evolved over time, there are ways to fix this.
My thruster is cavitating. What do I do?5.9.2022
Cavitation appears when the thruster propeller draws air from the surface, resulting in severely reduced thrust performance and significantly increased noise.
Finding the right thruster
How much power do I need from a boat thruster?15.4.2021
Thruster expert Runar Scott Jensen explains how to calculate the amount of power you will need from your bow and/or stern thruster.
Do I need a bow thruster on a small boat?15.4.2021
Small, shallow draft boats with narrow-angle, v-hull designs with light to moderate displacements are highly responsive, rewarding and great fun to drive at significantly higher than average cruising speed. So do you really need a bow thruster?
Factors that impact thruster efficiency15.4.2021
Using the input power rating as the deciding factor for the right thruster model might leave you with a severely underrated system as there are vast differences between input power and actual thrust output from various manufacturers.
Five benefits with variable speed control15.4.2021
Speed controlled thrusters have been in the wind for a while now. In this article, we break down the benefits of a PRO thruster system even further.
Pros and cons of different thruster solutions15.4.2021
Boats come in many different shapes and sizes. There are now bow and stern thruster solutions for virtually every type of motorboat and sailing yacht ever produced.
How to choose the right thruster for your boat15.4.2021
If you are considering installing a bow thruster on your boat, there are some things to consider before choosing the type and manufacturer. Here are the essential factors to contemplate in your planning.
