Rental Tug  /  Rental Towboat

Although this 9,500 mAh battery is no longer in stock, the following does illustrate how the tug's capacity can be used to carry additional batteries or equipment.

Thought about adding a rental concession to your museum? Would you like to have long-running low-maintenance boats for guests or students?

12.5 hours of continuous (full-power plus continuous rudder movement) use on one battery. Days of "stand-by" time (Assuming 80 mA receiver+ESC draw while sitting idle.)

It can be done! It has been done!  

Here is a ballast test of a standard Vac-U-Tug with our new battery system installed.
Note the rear water line is just where it should be.
The bow waterline is right in the middle of the keel curve.
Four ounces of ballast are still needed in the stern.
All ballast removed from the bow.
Trim the motor tray and install the optional battery tray with Velcro strips.
Now install the battery. 9,500 mAh NiMH 6-cell custom pack. Put your speed control between the steering servo and the receiver.
Nice and clean on the inside. Perfect ballast and waterline on the outside. This tug can go for MILES.

 The weight of the tug, receiver, ESC, and Servo equals 30 ounces. Install the 34 ounce battery. Total weight will be 64 - 65 ounces, the original stock gross weight for the tug.
