HOW TO SELECT THE
PROPER BATTERY
One of the very special features of this model boat is its
ability to properly and safely use the latest in LiPo battery
technology. Your boat will be lighter, faster and handle better
using this style of battery. If you do choose to use NiMH
battery packs in your UL-1 Superior you will experience a
decrease in overall performance.
WARNING: Please read and heed all warning information
that comes with your LiPo batteries.
Your UL-1 is designed to use two 7.4V LiPo packs. A 7.4 volt
LiPo battery pack is typically called a 2S pack, 2S meaning
two cells in series. Our UL-1 is designed to use two 2S packs.
The ESC connects the two 2S packs into a total of 4S or four
(4) cells in series for a total voltage supply of 14.8V.
IMPORTANT:
You are going to need to purchase batteries
that will be able to supply at least 60 amps average. If you
multiply the mAh (capacity) of the battery by the C (current)
rating you can determine the duration amperage the battery.
It’s easy. Here’s how. Lets do a sample calculation based on
the Great Planes Electrifl y 7.4V 3200mah 20C LiPo battery
(GPMP0622). 3200mAh is really 3.2 milliamps hour (mAh)
so, 3.2 x 20 (20 is our C rating on the pack) = 64 amps.
We have up to 64 usable amps average for the duration of
our run. Most LiPo batteries will allow the amps (current) to
spike above this rating but only for very short periods of time.
DO NOT USE A BATTERY PACK THAT CAN NOT DELIVER
THE MINIMUM REQUIRED AMPERAGE.
Also note that the ESC in your UL-1 is rated at 60AMPs.
This is ULTIMATELY the AMP rating you DO NOT want to
exceed regardless of the current rating of the packs. The
ESC will handle amperage spikes up in the 70amp range but
if operated continually at or above the recommended rating
you will damage the ESC. Your UL-1 Superior Hydroplane
(in stock confi guration) safely draws under the ESC current
rating. With higher pitch or oversize propellers your motor
and batteries can surpass the rating of the ESC and the ESC
can be damaged.
We do not recommend using more than
18 volts in your UL-1 Superior.
STORAGE AND SAFETY REGARDING LIPOS:
It’s a good idea to charge and store LiPo batteries in a
safe area or container. NEVER leave your LiPo batteries
unattended while charging. A metal surplus ammo box
makes a great storage and charge container. A LiPo sack
also works quite well.
If you have a bad crash and the battery has seen a hard
impact, set it on the ground and let it sit for 20 minutes before
charging it and placing it back in your safe storage container.
For best performance and safety, never discharge your LiPos
to below 2.9V per cell. Always use a balancer when charging
and store your packs fully charged.
If your LiPos sit charged for a long time you might fi nd that
running this charge out can cause the stutter warning system
to kick in during the fi rst minute or so of the run. It’s a good
idea to cycle your batteries the day before to reach maximum
power from the batteries.
EXTRA SUPPLIES
As with any hobby, it is a good idea to assemble a useful collection
of tools and accessories to bring along when you head to the
pond. Here are some items you will want to keep handy.
• Extra “AA” Batteries
• Rubber boots
• Spare prop
• Paper Towels
• Hobby knife
• Spray-On Cleaner
• Metric Allen Key
• Sunglasses
• Metric nut drivers
• Sun block
• Servo tape
• Folding table
• Extra hook and loop
• Lawn chair
• First-Aid kit
• Canopy or shelter
• Standard and phillips head screwdrivers
• WD-40 or other water displacing fluid
• Cooler with plenty of ice and water
