2018 Highlight

2018 Highlight

2018 brought some interesting projects for Q-SPD, the main highlight being 3 military patrol boats built in Abu Dhabi. Q-SPD supplied the complete propulsion driveline system along with the full steering package and end to end exhaust systems.

These DV15 Interceptors have become a popular model used by governments around the world as high speed patrol vessels. Previous built models have used trimmable surface drives, with this project the customer wanted a more reliable and user friendly option rather than the typical high maintenance and complex operational needs of trimming surface drives.
Q-SPD are the only non trimming surface drive able to deliver performance across the range as well as being extremely low maintenance and very operator friendly. Being extremely light weight and easy to install being a added bonus.

The DV15 Interceptors are powered by twin Catapillar C13 705hp engines and have a top speed of
52-56 knots (depending on version and payload).

Q-SPD supplied:
QSD130 Surface Drives
5 blade propellers
Full power steering solution
Drive shafts
Complete exhaust systems
Custom risers & mixers (designed in house)

2019 has kicked off with an order for another 3 Q-SPD Surface Drives for the same customer in
Abu Dhabi.

Q-Marine Power and Propulsion are the exclusive NZ distributer of Revolution Power Australia Lithium LiFePo4 Deep Cycle Batteries

Revolution Power Lithium LiFePo4 have been proven in the Australian outback and beyond, by 4WDs, caravans and motorhomes and for long haul trucking, marine and off grid solutions for over 6 years.  Reliability and high quality also see’s Revolution Power Lithium Ion Batteries being used by emergency and rapid response services.Â

Offered in 12V/60Ah, 100Ah, 160Ah and 24V/200Ah and 48V/100Ah, Revolution Power Lithium Ion Batteries offer some significant advantages others cannot equal:

Built in BMS (Battery Management System) -  Revolution Power’s internal battery management system is designed to equalise and balance the cells.  It will also turn the battery off if the voltage is too low or too high or if it short circuits.Â

Usable power – when talking about Amp Hours, Revolution Power talk usable amp hours. A 100Ah Revolution Power Lithium Deep Cycle Battery means 100 usable amp hours vs. only 50% usable with Lead and AGM batteries and typically only 80% usable from other Lithium brands.Â

Quick recharge – Revolution Power Lithium Ion Batteries offer very fast recharge.  With correct charge profile a 100Ah Revolution Power Lithium will fully charge from flat to full in 2 hours using a 40amp charger.

Less weight – lighter than even other Lithium Ion.  The 12V 100Ah Revolution Power Lithium Battery weighs just 11.9kg  vs. 32kg or more for an AGM 100Ah battery.

Constant voltage – Equipment and electronics will run more efficiently, as the voltage sits at 13.4v for 80% of the discharge cycle.  Traditional batteries voltage drops rapidly with high draw.

Longer cycle life – 5000 cycle @ 50% discharge vs. 80 – 500 depending on quality of an AGM.

Waterproof – Revolution Power’s 12V Lithium Battery range are all IP rated.  That means they are sealed in a polycarbonate case that is water proof.Â
