  • Lithium batteries has its cycle life, please replace old battery with new one when it reaches its service life or when it is two years old, whichever comes first.
  • Test battery properties is your own responsibility. Please test Li-Ion battery you bought from us before using or sell to your customer to ensure battery can be operated properly and safely in your device. 
General Guidelines and Warnings
  • Use specific Lithium Polymer/Li-ion charger only. Do not use a NiMH or NiCd charger- Failure to do so may a cause fire, which may result in personal injury and property damage.
  • Never charge batteries unattended. When charging LiPo/Li-ion batteries you should always remain in constant observation to monitor the charging process and react to potential problems that may occur.
  • Some LiPo/Li-ion chargers on the market may have technical deficiencies that may cause it to charge the LiPo/Li-ion batteries incorrectly or at an improper rate. It is your responsibility solely to assure the charger you purchased works properly. Always monitor charging process to assure batteries are being charged properly. Failure to do so may result in fire.
  • If at any time you witness a battery starting to balloon, swell up, smoke or hot, 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. Observation should occur in a safe area outside of any building or vehicle and away from any combustible material.

  • 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.
  • A battery can still ignite even after 10 minutes.
  • In the event of a crash due to bad shipment or other reason, you must remove battery for observation and place in a safe open area away from any combustible material for approximately 15 minutes.
  • 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.
  • To solder a connector: Remove insulating tape of Red wire and solder to positive terminal of a connector, then remove insulating tape of Black wire and solder to the negative terminal of connector. Be careful not to short the wire lead. 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.
  • Never store or charge battery pack inside your car in extreme temperatures, since extreme temperature could ignite fire.
  • Never drop the batteries.
  • We suggest you put the battery in an enclosure to protect it from damages by liquid or dropping from height accidentally.

Charging Process

  • Never charge batteries unattended.
  • Put battery in the fireproof container and charge in an isolated area, away from other flammable materials. Always have fire extinguisher for emergency use.
  • Let battery cool down to ambient temperature before charging.
  • 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.
  • 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.

a. Example: The label on a 2-Cell battery pack in series will read charge as 2-Cell (7.4V), or may cause fire. You must select 2-Cell for charging.

b. Example: The label on a 3-Cell battery pack in series will read charge as 3-Cell (11.1V), or may cause fire. You must select 3-Cell for charging.

  • Selecting a cell count other than the one printed on the battery (always confirm label is correct), can cause fire.
  • You must select the charge rate current that does not exceed the battery's allowed charging current. (Please double check the battery's specification)

Storage & Transportation

  • Store battery at room temperature between 40°F and 80°F for best results.
  • Do not expose battery pack to direct sunlight (heat) for extended periods.
  • When transporting or temporarily storing in a vehicle, temperature range should be greater than 20°F but no more than 150°F.
  • Storing battery at temperatures greater than 170°F for extended periods of time (more than 2 hours) may cause damage to battery and possible fire.

Caring for

  • Charge battery with good quality Lithium Polymer charger. A poor-quality charger can be dangerous.
  • Set voltage and current correctly (failure to do so can cause fire).
  • Please check cell voltage after the first charge.
    • Example
      • 1-Cell: 4.2V (4.15 to 4.22)
      • 2-Cell: 8.4V (8.32 to 8.44)
      • 3-Cell: 12.6V (12.48 to 12.66)
      • 4-Cell: 16.8V (16.64 to 16.88)
      • 5-Cell: 18.5V (18.30 to 18.60)
  • Do not discharge battery to a level below 3V per cell under load. Deep discharge below 3V per cell can deteriorate battery performance.
  • Use caution to avoid puncture of the cell. Puncture of cells may cause a fire.
  • Charging the battery every 2 months to keep it fresh if you don't use it.
Operating Charging Temperature:
