Battery Care

Warning! Always follow manufacturer warning labels when handling Lipo batteries.

In addition there are some common practices a user should follow to not void the warranty:

  • Break-in new packs by gently cycling them 3 to 5 times on a charger/discharger or in the model from full charge to no less then 50%- 60% of full mAh capacity.
  • Always check for excessive heat after a couple minutes of run time depending on the battery mounting location, and power draw of the model.
  • Let battery cool to ambient temperature prior to charging.
  • Always charge on a non-conductive surface to avoid shorting the battery or charging equipment.
  • Avoid running Lipos heavily during hot seasons where the outside temperature exceeds 95F/35C
  • Do not let keep Lipo batteries fully charged while not in use. Always discharge to storage (60%) until the next run time. This avoids premature "aging" of the cells.
  • Avoid discharging below 20% capacity. Doing so degrades the cells leading to high IR and reduces charge capacity.
  • Do not exceed recommended charge rates. A 5C charge rate implies a max input charge current of 25A on a 5000mAh battery regardless of the cell count.
  • Never charge un-attended.
  • Use lipo safe bags for charging/discharging and transportation/storage, and discontinue the use of batteries that are puffing or physically damages no matter how small.
