LiPo Battery Charging

  1. Use specific Lithium Polymer charger only! Non-compliance may a cause fire, which may result in personal injury and property damage.
  2. Do not let the voltage on the cells drop more than 2.75v / Cell. It is recommended to unplug the battery after use which would stop any further discharge of the pack!
  3. Never charge batteries unattended. Whenever charging Li-Poly batteries you should always remain in constant observation to monitor the charging process and react to potential problems that may occur.
  4. If at any time you witness a battery starting to balloon or swell up, discontinue charging process immediately, disconnect the battery and observe it in a safe place for approximately 15 minutes. This may cause the battery to leak, and the reaction with air may cause the chemicals to ignite, resulting in fire. Since delayed chemical reaction can occur, it is best to observe the battery as a safety precaution. Battery observation should occur in a safe area outside of any building or vehicle and away from any combustible material.
  5. Use caution to avoid puncture of the cell. Puncture of cells may cause a fire.
  6. Wire lead shorts can cause fire! If you accidentally short the wires, the battery must be placed in a safe area for observation for approximately 15 minutes. Additionally, if a short occurs and contact is made with metal (such as rings on your hand), severe injuries may occur due to the conductibility of electric current.
  7. In the event of a crash, you must remove battery for observation and place in a safe open area away from any combustible material for approximately 15 minutes.
  8. If for any reason you need to cut the terminal wires, it will be necessary to cut each wire separately, ensuring the wires to not touch each other or a short may occur, potentially causing a fire. If you accidentally cause the battery to short, place it in a safe open space and observe the battery for approximately 15 minutes. A battery may swell or even possibly catch fire after a short time.
  9. Never store or charge battery pack inside your car or building in extreme temperatures, since extreme temperature could ignite fire.

Charging Process

  1. Never charge batteries unattended; Charge in an isolated area, away from other flammable materials; Let battery cool down to ambient temperature before charging.
  2. Do not charge batteries packs in series. Charge each battery pack individually. Failure to do so may result in incorrect battery recognition and charging functions. Overcharging may occur and fire may be the result.
  3. When selecting the cell count or voltage for charging purposes, select the cell count and voltage as it appears on the battery label. As a safety precaution, please confirm the information printed on the battery is correct.
  4. Selecting a cell count other than the one printed on the battery (always confirm label is correct), can cause fire.
  5. You must check the pack voltage before charging. Do not attempt to charge any pack if open voltage per cell is less than 3.3v Example Do not charge a 2 cell pack if below 6.6v; 3 cell pack if below 9.9v.
  6. You must select the charge rate current that does not to exceed 1C (one times he capacity of the battery). A higher setting may cause fire. The below chart is calculated at 1 x capacity of pack. Example: 1800mAh: charge below 1.8Amps; 2200mAh: charge below 2.2Amps; 3600mAh: charge below 3.6Amps First Discharge: Keep the run time to 6-minute sessions with 15-minute breaks.
