Important LiPo Performance

and Care Information!

To get the most performance and safety from your LiPo 

battery, please read and understand the following information.

  

Always follow the manufacturer’s recommendation for 

charging and maintaining your batteries. We would, however, 
like to expand on this for R/C boating use.

  

Never leave a charger and battery unattended while charging.

  

Use only the recommended batteries and appropriate 

charger.

  

Refer to the instructions included with your charger for 

proper battery charging procedure.

  

For best performance and longest battery life, never charge 
your LiPos at a charge rate higher than 1C. (1000mAh = 

1amp, 2000mAh = 2amps and so on). Remove the battery 

pack from the model and charge in a LiPo Sack (GPMP0751) 
or other safe charge container.

  

We have found it best to use only 80% of the rated mAh of 

the battery pack per discharge (boat run). You will experience 
rapid depletion of battery pack performance if you continue 
to discharge your pack below the 80% usage target. 

NOTE: Your Atlantic II Harbor Tugboat’s ESC has a stutter 
bump warning system that warns you of low battery voltage. 

This system starts its warning at 10.2V total giving you time 

to bring the boat back to shore before the ESC cuts off at 
9.2V. This is a built-in safety system for you, your boat and 
your batteries. It’s important to note that a 2S pack (7.2V) 
will not operate your boat or any battery pack (i.e. number of 
cells) that falls below the listed warning and cut off voltages.

Although this system is in place we still recommend 

adjusting your run times to not exceed 80% battery usage.

Always unplug and remove the battery from the boat 

after use. NEVER leave your battery pack plugged into 
the boat when not in use.

  

Store your battery pack/s in a LiPo Sack (GPMP0751) or 

other battery containment device. It is best to store them in 
a cool, dry place and on a fire-resistant surface. It is also a 
good idea to charge your batteries to either a full charge (if 
you feel you will be using the packs frequently) or at 11.4V 
for a 3S pack (or 3.8V per cell) for longer storage.
