World Class Join thousands of customers around the world who depend on Admiral batteries to power their favorite RC airplanes, boats, helicopters and vehicles. For nearly ten years, Motion RC’s batteries have earned a global reputation for quality, reliability, power, product support, and price. |

Precision Made Admiral batteries are produced in a 100,000sq/ft, ISO 9000 facility by a team of over 700 workers. The highest quality raw materials are crafted with precision machinery to create the foundation of a safe and reliable battery. |

Balanced and Matched Each cell is balanced, aged, graded, and matched when creating a specific battery. This meticulous process allows lower graded cells to be removed from the Admiral production line and instead shuttled to other resellers. Admiral batteries only use the highest grade of cell. |
![]() |
Reliable Power Advanced techniques including atomic absorption spectrometry are used to ensure each battery pack and its constituent cells are produced using materials that meet exact formulas and are free from contamination. |
![]() |
Longer Life Don’t be fooled by other batteries which may arrive with lower graded cells that have been cycled dozens of times to give the illusion of initial power, at the expense of total lifespan. Admiral batteries are not excessively aged at the factory, meaning that they benefit from 5-10 “break-in” cycles to exercise the battery before it is submitted to high discharge conditions. Proper usage extends the effective lifespan of your battery. |
![]() |
Higher Value Admiral batteries feature a lower average cost per recharge, due to their higher performance sustained over a longer number of cycles. Admiral batteries are available in every size to fit your favorite RC car, helicopter, boat, tank, drone, jet, or airplane from Motion RC. |

It keeps the CG centered, but it does not come with any velcro to keep it in place. You can easily get 8+ minutes of flight time, more if the thermal activity is decent.
