General Guidelines and Warnings for Lithium Batteries

* 1) 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.
* 2) 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.
* 3) 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.
* 4) 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.
* 5) 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.
* 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) A battery can still ignite even after 10 minutes.
* 8) 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.
* 9) 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.
* 10) 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.
* 11) Never store or charge battery pack inside your car in extreme temperatures, since extreme temperature could ignite fire.

Lithium Battery Charging Process:

* 1) Never charge batteries unattended.
* 2) Put battery in the fireproof container and charge in an isolated area, away from other flammable materials. Always have fire extinguisher for emergency use.
* 3) Let battery cool down to ambient temperature before charging.
* 4) 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.
* 5) 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.

* 6) Selecting a cell count other than the one printed on the battery (always confirm label is correct), can cause fire.
* 7) 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
* Examples:
Do not charge a 2-cell pack if below 6.6v
Do not charge a 3 cell pack if below 9.9v

* 8) You must select the charge rate current that does not to exceed 1C (one times the capacity of the battery). A higher setting may cause fire. The below chart is calculated at 1 x capacity of pack. Example 2000 mAh: Charge below 2.0 Amps. We strongly recommend using our Li-ion battery charger to charge our batteries.
4800 mAh: Charge below 4.8 Amps
5500 mAh: Charge below 5.5 Amps
